The Dunning-Kruger Effect: The Journey from “I Know It All” to “I Can’t Do Anything”

Imagine a sunny morning in Pittsburgh, 1995. A man named McArthur Wheeler bursts into a bank in broad daylight. And some time later — into another one, with the same confidence in his own invulnerability. He does not wear a mask, does not hide his face, and does not even turn away from the surveillance cameras. Moreover, he looks straight into the lens and smiles. When the police arrest him a few hours later, showing him the recording with his perfectly readable face, Wheeler falls into sincere bewilderment. He is shocked. His face could not have been filmed because… he had rubbed it with lemon juice.

Wheeler knew that lemon juice is used as invisible ink: if you write with it on paper, the writing appears only when heated. He made a simple but fatal logical mistake: he decided that since letters disappear from paper, it means his face would also become invisible to cameras. He was not just mistaken — he was absolutely certain he was right. So certain that he went to rob a bank in broad daylight.

This story is not a joke and not the script of a comedy. It is a real case that inspired two psychologists from Cornell University to conduct a series of experiments that overturned our understanding of human self-assessment. And here is the question that you may have asked yourself at least once in your life, looking at a boss confidently leading a company to collapse, at a relative at the holiday table who talks about politics with the aplomb of a professor without reading the news, or at a colleague who takes on a complex project without having any idea which side to approach it from:

Why do people who understand the least about some subject most often speak louder than everyone else and look at you with superiority, as if they possess the ultimate truth?

This question is not idle. It runs through all areas of our lives — from kitchen arguments to meetings of boards of directors. It explains why the internet is full of couch experts on virology and international relations, why fortune-tellers and astrologers still flourish in the era of telescopes and MRI machines, and why we ourselves sometimes give confident advice on topics where our knowledge is only dust on the cover of a book. This paradox is the very mystery that we will be unraveling today.

Definition of the Dunning-Kruger Effect

Behind this story and this question stands a strict scientific concept known as the “Dunning-Kruger effect.” The essence of the phenomenon can be put into one short but very capacious paradox that turns our usual idea of confidence upside down:

People with a low level of competence systematically overestimate their abilities, while people with a high level of competence, on the contrary, tend to underestimate their abilities.

Let’s take this definition apart piece by piece, like a clockwork mechanism.

The first part is the most dangerous: “People with a low level of competence systematically overestimate their abilities.”

This does not mean that they are simply bragging or want to seem smarter. It means that they sincerely believe in their own genius. Their brain does not see the difference between what they know and what they do not know. They are so bad in some area that they do not even have the tools to assess their own badness.

Imagine a person who gets behind the wheel of a car for the first time in his life. He watched a two-minute video on YouTube, learned where the gas pedal is and where the brake is, and drove out onto a busy highway. He is sincerely sure that he will manage: “What is so difficult about it? Turn the steering wheel, press the gas — and that’s it.” He does not even suspect that there is a blind spot, that the car can skid on a wet road, that you need to look not only ahead but also in the mirrors, and that a distance of two car lengths is seconds away from a collision. He does not just drive badly — he does not suspect that there are many important skills he has not even heard of. He is happy and confident precisely because his horizons are too narrow to see his own ignorance.

Or another example — much more everyday. Imagine a person who heard the term “inflation” and read two posts on social media. Now he explains, foaming at the mouth, in any company why the economy will collapse tomorrow morning. He throws around smart words, draws graphs on napkins, and sincerely considers himself an economic guru. He does not even know that there are such concepts as the key rate, money supply, multiplier, or consumer price index. He does not know what he does not know. His confidence rests not on knowledge, but on absolute blindness to his own lack of awareness.

In psychology, this state is called “unconscious incompetence.” This is the first and most insidious stage. It is when you not only do not know how — you do not even suspect that there is something to learn. You are standing on top of a small hill of your superficial knowledge and mistake it for Everest because you have never seen real mountains. The scariest thing about this stage is not the lack of skills, but the lack of a meta-skill: the ability to look at yourself from the outside and admit: “Wait, it seems I understand nothing about this.”

The second part is the most tragic and paradoxical: “People with a high level of competence tend to underestimate their abilities.”

This is where the real irony begins. Imagine a professor who has been studying quantum physics for 30 years. He knows everything about it. But precisely because he knows so much, he realizes more sharply than any amateur how much he still does not know. He sees the boundless ocean of the unknown, sees tons of the most complex mathematical derivations that he has not yet mastered, and it seems to him that his own knowledge is only a pathetic drop in this ocean. He begins to doubt: “Did I understand this equation correctly? Am I worthy of my department? Or maybe I am simply pretending, and real scientists are much smarter than me?”

This phenomenon is called the “curse of knowledge.” The more you know, the more difficult the task seems to you, because you take into account thousands of nuances that a beginner does not even suspect. That is exactly why many brilliant specialists are terrible speakers. They painfully choose their words, make reservations, say “on the one hand… but on the other…”, and against their background, a lively beginner who does not know a single nuance looks much more convincing and confident.

So, the Dunning-Kruger effect is not about stupidity and not about intelligence. It is about blindness to one’s own blind spots. It is a cognitive distortion, that is, a systemic error in the work of our own brain. Our brain is arranged in such a way that, first of all, it strives to protect our self-esteem. And often it does this by distorting reality: it slips us a convenient “illusion of competence” so that we feel more confident, even if objectively we are drifting with the current of ignorance.

Now that we know what kind of beast this is, let’s formulate the main idea that will run like a red thread through our entire article. And it sounds encouraging, although at first glance it may seem frightening.

The Dunning-Kruger effect is not just an amusing psychological phenomenon that explains the behavior of eccentrics or ignoramuses. It is not a sentence and not a characteristic of “stupid people.” It is a universal law of learning that acts on each of us absolutely equally, regardless of IQ level, education, or social status.

Think about it: have you never felt like a complete idiot when starting to learn a new language, mastering the guitar, or figuring out programming? And do you remember the time when, after reading one book, you considered yourself an expert and gave advice left and right, and a year later, having gone deeper into the topic, suddenly realized how little you knew back then?

So, this is normal. It is not your personal flaw — it is an evolutionary mechanism. It works like a safety device: if at the beginning of any learning we saw the whole abyss of ignorance, we would be paralyzed by fear, and we would never learn anything. The Dunning-Kruger effect gives us the necessary “rose-colored glasses” at the start so that we at least dare to begin.

But! And here lies the main key to personal growth: the problem arises only when we get stuck at this starting stage. When we refuse to take off these rose-colored glasses, when we do not notice that we have passed the “entry” point, and continue to consider ourselves gurus without developing further. Self-deception becomes dangerous when it begins to interfere with learning.

The History of the Discovery: How Two Psychologists Exposed Self-Deception

In the late 1990s, at Cornell University, one of the most prestigious research centers in America, there worked a young social psychologist, already known for his meticulousness, named David Dunning. He was fascinated by how people make mistakes, and, more importantly, by how they do not notice their mistakes. Together with his graduate student, Justin Kruger, they constantly discussed one and the same mystery: why are there so many people around who are confident that they are right, but at the same time objectively talk complete nonsense?

Their insight did not happen in a laboratory or while reading scientific works. It came from a newspaper crime report, which they read completely by chance. It was the already familiar story of McArthur Wheeler — the robber who rubbed his face with lemon juice, sincerely believing that surveillance cameras would not film him.

Dunning and Kruger did not laugh at this case, as most people would have done. Instead, they asked themselves a fundamental scientific question, which sounded like this:

“If this person is so stupid that he does not understand elementary things, then how is he even capable of assessing his own stupidity? How did he decide that his plan was good? What happens in the head of a person who does not know obvious things, but at the same time is absolutely convinced of the opposite?”

It was then that they formulated a hypothesis that later turned psychology upside down: the skills necessary to perform a task correctly are the very same skills needed to understand that the task has been performed badly.

It sounds complicated, but the essence is simple. To realize that you are a bad chess player, you need to understand chess at least a little. To understand that your business plan is a hole, you need to understand how finance works. And if you are a complete zero in the subject, you simply do not have the tools to see your zero. You look at your result and see not mistakes, but “genius moves,” because the standard of the correct answer is simply inaccessible to you.

This brilliant guess became the starting point for their famous experiment, the results of which were published in 1999 in the most prestigious journal Journal of Personality and Social Psychology. And from that moment, the effect they described received their names and forever entered the golden fund of psychological science.

The Experiment: Students, Logic, Grammar, and a Sense of Humor

So, Dunning and Kruger had a hypothesis. But in science, a beautiful guess is not enough — it must be tested in practice. And they came up with an elegant, almost detective-like experiment that was built on four simple steps.

Step one: recruiting participants. They invited a group of students from Cornell University. These were ordinary young people — not geniuses and not failing students, but average students who agreed to participate in the study for credit or a small reward.

Step two: testing. The researchers divided the students into groups and gave them three completely different tests to rule out chance:

1. A test of logical thinking. Students were shown series of tasks for finding patterns, syllogisms (for example: “All cats are animals. All animals are mortal. Therefore, all cats are mortal? True or false?”), and tasks on deduction. This tested their ability to reason strictly and consistently.
2. A test of grammar and style. Participants were given texts with serious errors that had to be found and corrected, and they were also asked to assess the correctness of complex grammatical constructions. This tested their linguistic competence.
3. A test of sense of humor. This was the trickiest and most unusual point. Students were shown dozens of cartoons and jokes from well-known humor publications. Their task was to evaluate how funny and witty each joke was. But most importantly: the researchers had previously surveyed professional comedians and editors of humor magazines in order to determine the “standard” rating of what was funny. In this way, they could objectively compare the students’ ratings with the ratings of professionals.

Step three: self-assessment. After each student had completed all three tests, the most important moment came. The scientists asked each participant to evaluate their own results. But not abstractly, very specifically: they had to predict how many correct answers they had given (as a percentage) and what place they occupied among all the other participants in the experiment.

Step four: the most interesting part — comparison. Dunning and Kruger took two columns of numbers. In one column were the students’ real results (objective competence). In the second were their own predictions (subjective self-assessment). And they began to compare these columns in different groups of students.

They divided all participants into four groups according to the level of their real achievements:

• The bottom 25% — those who showed the worst results (the most incompetent).
• The second group — slightly better.
• The third group — good.
• The top 25% — those who showed the best results (the most competent).

It was precisely in this comparison that the very shocking picture appeared, which no one expected to see.

The Key Result: The Abyss Between Reality and Illusion

When Dunning and Kruger overlaid the students’ self-assessment onto their real results, they saw not just a scatter of data. They saw a systematic, mathematically expressed catastrophe of self-perception.

Here is what the numbers showed — numbers that forever changed psychology.

Shocking fact number one: “Blind leaders.”

Students from the bottom quartile — those who showed the worst results in all three tests — rated their skills significantly above average. For example, those who were objectively at the 12th percentile (that is, 88% of participants performed better than they did) believed, on average, that they were at the 62nd percentile (that is, that they were better than 62% of the others). Do you understand what this means? The weakest participants were confident that they were in the upper half of the group, almost at the top!

They were not mistaken by a couple of points — the gap between their real position and their belief in themselves was more than 50 percentile points. They were so bad at logic, grammar, and even at evaluating humor that they simply could not understand how bad they really were. They looked at their answers and saw brilliant solutions, because they did not have the standard of the “correct answer” in their heads. They were sure they had done everything brilliantly.

Shocking fact number two: “Modest geniuses.”

The opposite picture was observed among students from the top quartile — those who really showed brilliant results. They, on the contrary, underestimated themselves. Those who were objectively at the 88th percentile (that is, were better than 88% of participants) believed that their results were somewhere around the level of the 70th percentile.

Why did this happen? Because smart people see complexity. They solved the tasks, saw nuances, noticed that some tasks were tricky, and thought: “If this was difficult for me, then it must surely be difficult for others too. So I probably did about average.” They projected their own difficulty onto others. They did not understand that for the others these tasks were not simply difficult, but unsolvable. Experts simply could not believe in their own exceptionality, because it seemed to them that if they had managed — then it was easy, and everyone else had managed in the same way.

And the most amazing discovery awaited them at the end, when they offered the most incompetent students additional training. After the weakest participants were shown the correct answers and had it explained to them where they had made mistakes, what happened? These students did not fall into denial. They honestly said: “Oh, so that is how it should have been solved. Now I understand. I really was wrong.” And, most importantly, after this brief training, their self-assessment sharply dropped to an adequate level. For the first time in their lives, they realized their incompetence.

This was the triumph of Dunning and Kruger’s hypothesis. They proved that the problem is not that people are stupid. The problem is that incompetence deprives a person of the ability to realize their own incompetence. It is a double blow: you make mistakes and you are unable to notice them.

The “Double Burden” of Incompetence

It was precisely this paradox that Dunning and Kruger called the most important conclusion of their study. They formulated it as the “double burden” of incompetence.

What does this mean? Let’s break it down.

The first burden is the direct mistakes. A person does not cope with the task. He makes wrong decisions, commits logical failures, writes illiterately, does not feel humor. This is the first, obvious problem. He cannot.

The second burden is the absence of metacognition. A person not only cannot do something correctly. He cannot even understand that he is doing it incorrectly. His brain does not give him feedback. He looks at his work — and sees a masterpiece. He looks at an expert — and sees a bore who “overcomplicates things.” He is firmly convinced that everything is fine.

It is precisely this second burden that is the most dangerous. Because the first burden (mistakes) can be corrected through learning. But in order to start learning, you first need to admit that you are mistaken. And how can you admit a mistake if your own brain tells you that there are no mistakes? This is a closed circle.

Imagine a person who picks up a guitar for the first time in his life. He strikes the strings, a terrible roar comes out, but he says: “Cool! I am almost like Hendrix!” His neighbor, who has been playing for 20 years, hears this roar and grimaces. Which of them is closer to the truth? The beginner is confident in his talent because he does not know what correct music sounds like. He does not distinguish notes from noise. He has no standard. And the expert has a standard, and therefore he hears every false note and sometimes is even embarrassed to play in public.

Dunning and Kruger placed a scientific foundation under this everyday wisdom. They showed that:

1. Incompetent people not only come to wrong conclusions, but their incompetence also deprives them of the ability to realize it.
2. This effect manifests itself not in some one narrow area, but in the most diverse spheres — from solving logical tasks to sense of humor and grammar.
3. And most importantly: this effect is not a sentence. As soon as a person receives feedback and their knowledge expands to a minimal level, their self-assessment becomes adequate.

It was precisely this conclusion that gave hope. The Dunning-Kruger effect is not about the world being divided into “smart” and “stupid.” It is about the fact that all of us are potential victims of this effect in those areas where we are amateurs. And the key to getting out of the trap is not the denial of our incompetence, but the honest admission: “I may be mistaken. And right now, perhaps, I am mistaken. Let’s check.” It is precisely with this admission that real wisdom and real learning begin.

The Essence of the Effect: At the Center Is Metacognition

Now that we know the history of the discovery and have seen the shocking numbers of the experiment, let’s look into the very depth of the mechanism. Why does the brain deceive us so cruelly? Why does it allow us to feel like geniuses when we are objectively failing at a task?

The answer lies in one smart word that sounds like “metacognition.” Do not be frightened — behind this terminology is hidden an amazingly simple and important thing that you encounter every day.

Let’s take the word apart piece by piece. The prefix “meta-” translated from Greek means “above,” “higher,” “about itself.” And “cognition” is everything connected with knowing: thinking, memory, attention, understanding, decision-making. Therefore, metacognition is thinking about one’s own thinking. It is the ability of your brain to rise one floor higher and look at itself from above. It is the inner observer who sits in your head and comments: “So, right now I am thinking about this task. But am I solving it correctly? Have I forgotten something? Do I really understand this?”

Metacognition is your personal built-in radar that scans the quality of your own thoughts. It is the difference between simply thinking and thinking about how you think.

I will give an example from life so that it becomes completely clear. Imagine that you are learning a foreign language. You have learned 50 new words and feel like a good fellow. This is cognition (the process of memorization). But when you catch yourself thinking: “Hmm, I am not sure that I remembered the pronunciation of this word correctly. It seems I am confusing the stress,” — this is already metacognition. This is your inner critic evaluating the quality of your memorization.

Or another example — you are reading a difficult article. Cognition is when you simply run your eyes over the text. Metacognition is when you stop and ask yourself: “Did I even understand what is written here? Or am I just looking at letters? Maybe I should reread the paragraph once more?”

It is precisely this ability — to look at one’s own thoughts from the outside and evaluate their accuracy — that is the key mechanism that either saves us from the Dunning-Kruger effect or throws us into its trap.

Why Beginners Overestimate Themselves

Now that we know what metacognition is, let’s look at what happens when this inner radar is absent or works with interruptions. And we will start with the most dramatic group — beginners who overestimate themselves by dozens of percentile points.

Why are they so confident in their genius? The reason is not malicious intent and not arrogance. The reason is much deeper and more insidious.

Reason one: they lack the knowledge to understand what exactly they do not know.

This is the main paradox that Dunning and Kruger discovered. Imagine that you have never seen a chessboard. You only know that there are pieces and they need to be moved somehow. You sit down to play with a grandmaster and make the first move. You made a move. The grandmaster thinks. You think: “Well, there, I puzzled him! I am probably a brilliant strategist!” In reality, the grandmaster is thinking not because your move was brilliant, but because he is trying to understand how it was even possible to make such a meaningless move. But you do not know this. You do not have the standard of a “correct move” in your head. You look at your board, at your pieces, and see not chaos, but a field for maneuver. Your ignorance is your rose-colored glasses. It hides from you the whole depth of your own lack of talent.

And here is what is important: this is not about low IQ. This is about the absence of information. If you do not have a map of the area, you cannot understand that you are lost. If you do not have the standard of the correct answer, you cannot understand that you answered incorrectly. You simply do not know what competence looks like. Therefore your self-assessment is formed not on the basis of objective criteria, but on the basis of an inner feeling: “I tried, I made an effort, so I did well.”

Reason two: the absence of a “standard” — they simply do not know what competent work looks like.

Let’s imagine another situation. You have never seen or baked bread in your life. You went into the kitchen, mixed flour, water, salt, and yeast “by eye,” put it into the oven, and took out a burnt brick that was raw inside. But! You do not know what a real, ideal baguette should look like. You do not know what kind of crust it should have, what kind of crumb, what kind of aroma. You look at your brick and think: “Well, bread is bread. Hard, but edible. I probably did not do badly.” And next to you stands a professional baker who has been baking crispy croissants for 20 years. He takes your “bread” and simply falls silent from horror. But you do not see this horror. You do not know the standard, you have never tasted real bread, and therefore your internal standard of quality is catastrophically lowered.

This is that very “blindness to one’s own blindness.” A beginner does not simply not know how to do something correctly. He does not know how it should be correctly. Therefore any craft of his seems to him a masterpiece. He compares his result not with an abstract ideal, but with emptiness. And in comparison with emptiness, any mistake looks like an achievement.

That is exactly why it is so difficult to argue with a person who is sure that he has understood a topic after reading one article on the internet. He does not have the volume of knowledge that would allow him to see all the nuances, all the “underwater stones,” all the exceptions to the rules. He sees only the tip of the iceberg and thinks that this is the whole iceberg. His confidence is not insolence. It is a sincere but tragic delusion generated by the absence of metacognitive skills.

Why Experts Underestimate Themselves

And now let’s turn the medal over. We have dealt with those who overestimate themselves. But the second part of the Dunning-Kruger effect is about those who underestimate themselves. Why do the smartest and most competent people often doubt themselves, sit quietly in the corner, and feel embarrassed to express their opinion?

Here the exact same mechanism of metacognition works, but in the exact opposite way. In an expert, the radar works too well, and he sees not only his competence, but also its boundaries. And this immediately gives rise to three powerful effects that make geniuses doubt themselves.

Effect one: “The curse of knowledge.”

This is a psychological phenomenon that sounds beautiful and tragic at the same time. Its essence is that the more you know, the harder it is for you to imagine that other people do not know this.

Imagine that you are a professional pianist. You have played since the age of five, you have perfect pitch, you know where every note is on the keyboard without even looking. For you, taking a C major chord is as natural as breathing. You look at a beginner who is trying to press three keys at the same time and think: “Well, is this really difficult? It is elementary!” You forget that 30 years ago you also could not do this. You project your knowledge onto others. And when you solve a difficult professional task, you think: “I solved it. So it was easy. So anyone else would have solved it too. So I am not so brilliant after all.”

You do not see your own exceptionality because your internal standard of “normal” is yourself. You forget that what is “normal” for you is “the highest level of skill” for another person. That is exactly why many professors are terrible lecturers. They speak in complex terms, make quick logical jumps, and are sincerely surprised when students understand nothing. They cannot get into the beginner’s head and remember what it is like not to know.

Effect two: they overestimate the competence of those around them.

An expert has a clear picture of the world. He sees how many shades, nuances, and complex interconnections exist in his field. And he sincerely believes that if he knows these nuances, then most people around him know them too. He thinks: “Well, this is obvious. All normal people should understand this.”

And when he looks at his achievements, he compares them not with the real level of the average person, but with that high ideal level that exists in his head. And compared with this ideal level, his own knowledge seems modest to him. “I know that there are still thousands of articles I have not read. There are dozens of theories I have not fully mastered. So I am still not competent enough.” He underestimates himself because his internal standard of “good” is extremely high.

Effect three: impostor syndrome as a logical continuation.

When a competent person faces a task where there is even the slightest uncertainty, he begins to doubt. His brain tells him: “Stop, I see that there are underwater stones here. I am not completely sure. What if I make a mistake? I am probably just pretending that I understand this.” He has an incredibly developed inner critic because he sees all his mistakes, even the smallest ones. A beginner simply does not notice them.

The result: the expert looks at his brilliant work, sees in it one tiny blot that is noticeable only to him, and thinks: “I am good for nothing.” And the beginner looks at his terrible result, does not see a single mistake, and thinks: “I am magnificent.” Such is the cruel irony of the human psyche.

The Irony of the Effect: The Circle Has Closed

Now let’s gather all the puzzle pieces into one picture. Look at what a deadly irony is hidden in the Dunning-Kruger effect. An irony that the researchers themselves call “the main paradox of incompetence.”

It sounds like this:

The very skills necessary for the high-quality performance of a task are the very same skills that are needed in order to understand that the task has been performed badly.

To write a good text, you need to feel the language, know grammar, understand the logic of narration. But exactly those same skills — a feel for language, knowledge of grammar, understanding of logic — are needed for you to read your own text and understand: “But it is terrible. The grammar limps, the logic jumps, the style is clumsy.”

If you do not have these skills, you will write a bad text and will not notice it. You will sincerely consider it a masterpiece. If you have these skills, you will write a good text, but you will notice that it is not ideal (because your taste is already more refined), and you will consider it mediocre.

Here it is, the main irony: to see your incompetence, you already need to be competent enough. And if you are incompetent, you cannot see your incompetence, because you do not have the tools for it. It is like trying to repair a watch without having a screwdriver. And you do not even know that a screwdriver is needed. That is exactly why the Dunning-Kruger effect is so difficult to defeat “from the inside.”

But there is also good news. Awareness of this irony is already half the way to salvation. When you understand that your brain can deceive you, when you realize that your confidence may be an illusion, and your doubts may be a sign of depth, you receive the key.

The Competence Curve: A Map of the Path from Ignorance to Wisdom

Now that we have examined the mechanics of the effect and understood why the brain so insidiously deceives us, let’s look at how this deception unfolds over time. The Dunning-Kruger effect is not a static characteristic that is forever stuck to a person. It is not a diagnosis of “stupidity” and not a label of “genius.” It is a process that each of us lives through again and again every time we take on a new task.

And like any process, it can be depicted on a graph. This graph is one of the most famous pictures in modern psychology. It is called the “Dunning-Kruger curve” or simply the “competence curve.”

Let’s imagine this graph. Let’s draw two axes in our imagination.

• The horizontal axis (the X axis) is your real knowledge and experience. It goes from left to right: from zero (“I have never touched this topic”) to maximum (“I have spent thousands of hours on this”).
• The vertical axis (the Y axis) is your self-confidence. It goes from bottom to top: from complete uncertainty (“I know nothing, I am a nothing”) to euphoric self-confidence (“I am a genius, I know everything”).

Now on this graph, if we start marking how a person’s confidence changes as he accumulates real knowledge, the result will be neither a straight line nor a smooth curve. The result will be a bizarre loop, resembling a mountain ridge with a cliff. And in this loop there are four key points that psychologists call:

1. “The peak of stupidity” — the place where confidence goes off the scale, while knowledge is almost absent.
2. “The valley of despair” — the place where confidence falls to zero, while knowledge is still small, but the person has already understood how much he still has to learn.
3. “The slope of enlightenment” — a long and difficult ascent where confidence slowly grows together with real knowledge.
4. “The plateau of stability” — the place where knowledge is enormous, and confidence is calm, measured, and adequate.

Each of these points is an entire universe of experiences through which any person passes, from a child who is learning to tie shoelaces to a scientist who is mastering a new area of physics. And the most important thing to understand is this: there is nothing shameful in being at any of these stages. What is shameful is only getting stuck in them or denying that you are there.

And now let’s go through each of these stages in detail, as if along a map.

Stage 1. “The Peak of Stupidity”

So, you take on a new task for the first time. You have never played tennis, never written code, never cooked soup, never understood politics. You are an absolute zero in this topic. But your consciousness does not know this. And it is here, at the very beginning of the path, that the most amazing and most dangerous psychological trick happens.

Your confidence soars to the skies. You feel almost like a genius.

Why does this happen? Remember what we talked about in the previous section. You have no standard of the correct answer. You do not know what competence looks like. You read one article on the internet, watched a five-minute video on YouTube, tried to do something once — and it seemed to you that you understood everything. Your brain tells you: “Well, it is logical! Everything is simple! I figured it out! It is elementary!”

At this stage, you are not simply confident — you are aggressively confident. You are ready to argue with experts, correct professionals, give advice left and right. You do not perceive criticism because your brain does not see mistakes in your actions. You look at your results and see brilliant success.

What does this look like in life?

• Example 1: Cooking. A person boiled a hard-boiled egg for the first time in his life. The egg is overcooked, rubbery, with a blue rim around the yolk. But the person says: “Delicious! I am a born cook! Tomorrow I will open a restaurant!”
• Example 2: Programming. A beginner developer wrote his first “Hello, World!” — the simplest program that displays two lines of text on the screen. He already mentally imagines himself as Steve Jobs. He believes that he understands how computers work and is ready to give advice to senior developers with 20 years of experience.
• Example 3: Psychology (meta-irony!). A person read one article about the Dunning-Kruger effect and is now sure that he has “figured out psychology” and can diagnose everyone around him. He points his finger at colleagues and says: “You all have this effect! But I have understood everything!”

At this stage, a person DOES NOT KNOW what he does not know. He stands on the top of a small hill of his superficial knowledge, but it seems to him that this is Everest. He is happy, he is energetic, he is full of enthusiasm. And that is exactly why this stage is so dangerous. Because if you get stuck at the “peak of stupidity,” you stop learning. Why learn if you already know everything? You close off access to real knowledge for yourself.

An important nuance: the “peak of stupidity” is not about a person being bad or stupid. It is about the fact that he has just begun. This is a natural, normal, and even useful stage. Without this starting self-confidence, we would never dare to begin something new. If we saw the whole abyss of ignorance from the very beginning, we would be paralyzed by fear. So the “peak of stupidity” is our biological “bumper” that gently pushes us forward. But you cannot stay on it.

Stage 2. “The Valley of Despair”

And then what people call a “collision with reality” happens. You continue to learn, try, make mistakes. And at some point — bam! — an insight happens.

You accumulate enough knowledge to understand: you know nothing. Your internal radar (metacognition) has finally switched on. You begin to see mistakes that you did not notice before. You encounter experts, read complex books, try to solve a real task — and fail with a crash. And here there is a sharp collapse of confidence.

From the “peak of stupidity,” you fly downward, into the “valley of despair.”

This is the most painful, the hardest, the most demotivating stage on the entire path. You feel like a complete nothing. You look at your previous achievements (which seemed genius to you) and understand that they were funny and pitiful. You feel shame, disappointment, anger at yourself. It seems to you that you will never learn, that you are “not made for this,” that everyone around you is smarter and more talented.

Here is what you think at this stage:

• “I am a complete idiot. How could I think that I understood anything?”
• “Everyone succeeds, but I do not. I am hopeless.”
• “I will never be able to learn this. It is too difficult for me.”

What does this look like in life?

• Example 1: Learning a foreign language. You learned 200 words, felt like a good fellow. And then you tried to speak with a native speaker and did not understand a single word of his fast speech. You could not build an elementary sentence. And you think: “I am terrible. I will never learn this language. Why did I even start?”
• Example 2: Sports. You went to the gym for a month, felt almost like an athlete. And then a professional trainer came and showed that you are doing absolutely all the exercises incorrectly, with terrible technique that can harm you. And you think: “I do not know how to do anything. I am just wasting time.”
• Example 3: Professional growth. You have just graduated from university, received a diploma, and felt like an expert. And then you got your first job and understood that 90% of what you studied does not work in real life, and 80% of the necessary skills you were not taught at all. And you feel not like a specialist, but like a frightened child.

The most important thing to understand about the “valley of despair”: this is not a failure. This is a sign of growth. This is the moment when you moved from “unconscious incompetence” to “conscious incompetence.” You stopped being blind to your blindness. You finally saw the real picture. This is not a step backward — this is a giant step forward. This is the most important turning point on the entire path. If you have reached the “valley of despair,” you are no longer a beginner. You have become a student.

But the most dangerous thing at this stage is the risk of giving up. Many people, finding themselves in the valley, think: “If I am this bad, why continue?” And they abandon the matter forever. They remain at the bottom. True mastery begins precisely with the fact that you decide: “I am terrible at this. And I will continue despite this.”

Stage 3. “The Slope of Enlightenment”

You have survived the valley of despair. You did not give up. You accepted your incompetence as a fact and decided to move on. And here the most interesting thing begins — a slow, difficult, but incredibly valuable ascent.

On the “slope of enlightenment,” you begin to accumulate real knowledge. Now you already know what the correct answer looks like, you see your mistakes, you learn from them, you read, practice, make mistakes again, correct yourself. Your confidence begins slowly, centimeter by centimeter, to rise upward.

But there is an important nuance: at this stage, your confidence grows more slowly than your real knowledge. Why? Because you are no longer that naive person from the “peak of stupidity.” You have seen the abyss. You know how many difficulties exist. You have become more modest. You know that even what you have learned is only the tip of the iceberg. You no longer shout “I am a genius!” but say: “Hmm, I am beginning to understand something, but I still have a lot to learn.”

At this stage, the most significant discoveries and the deepest insights happen. It is here that you:

• Begin to see connections where before you saw chaos.
• Can explain complex things in simple language.
• Realize that even experts make mistakes, and this is normal.
• Stop being afraid of mistakes and begin to use them as a learning tool.
• Feel that the learning process is becoming not a struggle, but a fascinating journey.

What does this look like in life?

• Example 1: Learning a language. You still do not speak fluently, but you can already maintain a simple conversation, understand the main idea of your interlocutor, and do not panic when you hear an unfamiliar word. You know that in a year you will speak better, and this does not frighten you, but inspires you.
• Example 2: Profession. You are no longer that “green beginner,” but you are not a “seasoned expert” either. You confidently solve standard tasks, know how to find answers to non-standard questions, and colleagues begin to turn to you for advice. You feel that you are growing, and this brings you pleasure.
• Example 3: Creativity. You write texts, draw, or compose music. Your works no longer make professionals laugh, and sometimes even receive praise. But you yourself see hundreds of flaws in each of your works and strive for perfection, understanding that it is unattainable, but that one must strive toward it.

On the “slope of enlightenment,” you enter a state that psychologists call “flow.” You are fully immersed in the process, time flies unnoticed, you get pleasure from overcoming difficulties. This is the most productive and happiest stage of your path.

Stage 4. “The Plateau of Stability”

And finally, you reach the top. No, this is not the “peak of stupidity.” This is a completely different peak. It is not so high, it is not so bright and euphoric. It is calm, steady, and firm. This is the “plateau of stability.”

What happens here? Your real knowledge has reached a high level. Your confidence has finally caught up with it. You have reached balance. You no longer overestimate or underestimate yourself. You know what you can do, you know what you cannot do, and you know where the boundaries of your competence are. And you calmly, without excessive pride and without false modesty, use your skills.

On this plateau, an expert differs from a beginner not only in the fact that he knows more. He differs in his attitude toward his knowledge:

• He does not shout about his genius. He does not need constant confirmation that he is right. His confidence is internal; it does not depend on praise from those around him.
• He calmly admits his mistakes. He says: “I can be wrong,” — and this does not lower his authority, but, on the contrary, raises it. Because a real expert is not afraid to show that he is human.
• He knows the boundaries of his knowledge. He does not give advice in areas where he is incompetent. If he is asked about something he does not know, he answers: “I am not a specialist in this matter.”
• He treats other experts with respect. He knows that even in his field there are people who know more. He does not compete, but cooperates.
• He continues to learn. The plateau is not the end of the path. The expert understands that even on the plateau there are new horizons. He continues to develop, but already without panic and without euphoria. Calmly, methodically, with pleasure.

What does this look like in life?

• Example: An experienced doctor. He can make a complex diagnosis, but always double-checks his assumptions. He reads new studies, attends conferences. He tells patients: “I think that this is so, but let’s do additional tests to make sure.” He is not afraid to admit if he does not know something and to refer the patient to another specialist. His colleagues and patients trust him boundlessly because he combines knowledge, experience, and wisdom.

“The plateau of stable competence” is the state of a master. It is not about pride, but about dignity. It is when you stop fighting ignorance and simply begin to live in harmony with your knowledge. You have become what is called “a true professional.”

Important Afterword: This Path Is Endless

And finally, the most important thought to take away from this chapter. The path from the “peak of stupidity” to the “plateau of stable competence” does not end on any plateau.

Life is constant movement. We constantly take on new tasks, master new areas, face new challenges. Every time you begin something new, you again find yourself at the “peak of stupidity.” And this is normal! It does not mean that you have rolled back. It means that you are growing.

A true master is not the one who has reached the top and stopped. It is the one who knows how to:

1. Realize which stage he is at at the current moment.
2. Accept this stage without shame and self-abasement.
3. Not get stuck at the “peak of stupidity” and not give up in the “valley of despair.”
4. Continue moving forward, knowing that the “slope of enlightenment” leads to a new “plateau,” and from there — to a new challenge and a new “peak of stupidity” in another area.

This is the main skill of the twenty-first century — the skill of learning and relearning. And the Dunning-Kruger curve is not an enemy that must be defeated. It is a map that will help you not get lost in your own learning and not leave the path when it becomes difficult.

The Dunning-Kruger Effect in Action: Where We Encounter It Every Day

If there is a place where the Dunning-Kruger effect manifests itself most destructively and expensively, then it is, without a doubt, the world of business and corporate management. Here the price of a mistake is measured not in a spoiled mood, but in millions of dollars, lost profit, destroyed careers, and bankruptcies.

The most dangerous character in any office is the confident incompetent manager.

Such a manager has read two books on management, watched several motivational TED videos, and now firmly believes that he is the reincarnation of Steve Jobs. He gives instructions without getting into the essence of the processes. He makes strategic decisions based on intuition, which upon closer inspection turns out to be simply a lack of knowledge. He does not listen to experts because he believes that he understands better himself.

What does this look like in practice?

• Example: The “genius” strategist. A company leader who understands nothing about marketing decides to launch a large-scale advertising campaign. He chooses promotion channels because he “likes them,” assigns a budget based on his “gut feeling,” and sets unrealistic KPIs. The marketers try to explain that it does not work that way, that hypotheses need to be tested, the audience analyzed, and unit economics calculated. But the leader brushes them off: “You are just jealous of my genius! I understand everything! We do it the way I said, period!” The campaign fails, the money burns up, the company loses its position. But the leader does not admit his mistake. He blames the marketers, the market, the economic situation — anyone but himself. He continues to be confident that he is right because he does not have the metacognitive skills to see his incompetence.
• Example: Hiring employees. An HR specialist or manager who does not understand the subtleties of a profession conducts interviews. He looks at a candidate who speaks beautifully, carries himself confidently, uses fashionable terms (which the manager heard at the last conference). The manager thinks: “Oh, this guy is fire! He is confident, he makes an impression! I am taking him!” But a real professional, who knows all the nuances, is careful in his wording, talks about risks, about complexities, and looks less impressive. And the manager does not hire him. As a result, a handsome talker appears in the company who cannot do anything, while a real expert passes by. This is a classic example of how the Dunning-Kruger effect in hiring leads to catastrophic personnel mistakes.
• Example: Startup failure. A huge number of startups fall apart not because of a lack of money, but because of the “founder syndrome” of someone who is on the “peak of stupidity.” A young entrepreneur comes up with a “genius idea” that has already been implemented 10 times and failed, or that does not solve any real problem. He does not conduct market research because “he already knows everything anyway.” He does not consult experts because “experts are conservatives, they understand nothing about innovation.” He invests all the money into a product that nobody needs and discovers with surprise that nobody buys it. His confidence is not a strategy, it is a cognitive distortion.

Why does this happen so often in business? Because at the top of the corporate hierarchy there are not only the most talented people, but also the most ambitious. And ambition often interferes with a sober assessment of one’s skills. It seems to a leader that since he managed to rise to the top, it means he understands everything. This is a dangerous delusion — the “effect of transferring competencies.” The ability to manage people does not automatically make you an expert in marketing, finance, development, or law.

What should you do if you are a manager? The most important thing is to stop being the smartest person in the room. Surround yourself with people who know more than you in their field. Learn to listen and ask questions. Learn to say the phrase, “I am not a specialist in this matter, let’s listen to the expert.” This is not a sign of weakness, it is a sign of wise leadership.

In Politics and Public Discussions

If business is the place where the Dunning-Kruger effect hits the wallet, then politics and public discussions are the place where it hits our common sense and our ability to reach agreements with one another. This is perhaps the most toxic and visible arena for this cognitive distortion.

Why are political debates so aggressive? Why do people who understand absolutely nothing about economics, geopolitics, or medicine speak as if they are the main experts of the planet? The answer is the Dunning-Kruger effect.

Polarization of opinions: confidence is inversely proportional to knowledge.

Studies show that people with the strongest political convictions often know the least about the subject of their convictions. They do not read primary sources, do not study statistics, do not analyze context. They watch one channel, read one Telegram channel, communicate with people from their own bubble — and on this basis build an unshakable picture of the world.

They do not even suspect that there is an alternative point of view that also has the right to exist. They do not know about the complexities and compromises that exist in real politics. They do not know how the state machine actually works. But they are 100% confident. Their confidence is not knowledge, it is identification: “I think this way, which means I belong to this group. And this group is right. Everyone else is the enemy.”

That is exactly why it is difficult to have a constructive dialogue with a person who is on the “peak of stupidity” in politics. He does not perceive facts that contradict his picture of the world. He does not hear arguments. For him, discussion is not a search for truth, but a battle for victory. He does not allow the thought that he may be wrong, because his self-esteem is too strongly tied to his political views. To show that he is wrong means to destroy his personality. Therefore, he will defend himself with fury.

The Spread of Fake News: Who Believes Disinformation?

One of the most important discoveries of recent years in social psychology is connected with how the Dunning-Kruger effect influences the spread of fakes. It turns out that people who are worst at distinguishing truth from lies are most inclined to trust disinformation and spread it further.

Why? Because they do not have those very media literacy skills that are needed to critically evaluate information. They do not check sources, do not compare facts, do not analyze logic. It seems to them that “if it is written on the internet, then it is true.” They repost a fake, confident that they are doing a good deed — “warning” others. They do not even suspect that they are being used.

Studies show that the less a person knows about a topic (for example, about virology during a pandemic), the more confidently he gives advice — “wear masks!”, “do not wear masks!”, “it is just the flu!”, “it is a biological weapon!” Their confidence has nothing to do with real knowledge. They sincerely believe that they have figured out the issue because they read three posts on social media. And real scientists, who studied viruses for decades, spoke carefully, with reservations, with references to research — and their voices drowned in the chorus of couch experts.

How not to become a victim of this in politics? First, honestly admit to yourself that you do not understand most complex issues. Second, stop getting information from one source. Third, learn to ask yourself the question: “Where do I know this from? How can I check this information? And what do experts in this field say?”

In Medicine and Education

These two spheres — medicine and education — are especially sensitive to the Dunning-Kruger effect because people’s health and future are at stake here. And here, paradoxically, both beginners and those who should be the support of the system can suffer.

Medicine: interns and amateur patients.

• Problem number one: young doctors. Imagine an intern who has just graduated from medical university. He knows the theory, he passed the exams, he feels like a real doctor. He encounters a patient with strange symptoms, and the intern instantly makes a diagnosis. He is sure that this is a rare disease that he learned from a textbook. He does not pay attention to details, does not conduct differential diagnosis, does not order additional tests, because he is 100% sure. But an experienced doctor with 30 years of experience would look at the same patient and say: “Stop, the symptoms look like a dozen different diseases. We need to check everything. Let’s not rush.” The intern rushes. The intern is on the “peak of stupidity” — he does not know how many exceptions to the rules exist. And his self-confidence can cost the patient their health.
• Problem number two: amateur patients. In the age of the internet, every second patient comes to the doctor and says: “I read on the internet that I have cancer” or “I read that this is treated only with garlic, and I refuse your pills.” They have neither medical education nor even basic knowledge of how the body works. But they are sure that they know their diagnosis better than a professional doctor who studied for many years and has thousands of hours of practice behind him. This is a classic example of the “peak of stupidity”: the patient learned one symptom, it matched one article, and now he is an “expert.” He does not know what he does not know — about hundreds of other diseases that produce the same symptoms, about side effects, about contraindications, about the subtleties of dosages.
• The doctor’s paradox: Interestingly, experienced doctors, on the contrary, often suffer from impostor syndrome (which we will talk about later). They doubt, double-check, consult with colleagues. They never say “I am 100% sure,” because in medicine anything can happen. But a patient who does not know medicine does not see these doubts and may think that the doctor is “incompetent.” And a self-confident intern who “knows everything” seems more convincing to the patient. This is a tragic irony.

Education: pupils, students, and teachers.

• Problem: “I know everything” among students. A student who has just listened to a lecture thinks that he has understood the topic. He does not open the textbook, does not solve problems, does not ask questions. He goes to the exam absolutely confident in his knowledge — and gets a bad grade. Why? Because he confused the illusion of understanding with real understanding. His confidence was the result of hearing familiar words and thinking: “Ah, I know this!” But in reality he could not apply this knowledge in practice, could not explain it to others, could not answer clarifying questions. This is the classic Dunning-Kruger effect: the student was so incompetent that he could not understand that he had understood nothing.
• Problem: teachers on the “peak of stupidity.” There is also the opposite situation: a teacher who has been teaching a subject for 20 years has become so used to his material that he forgets what it is like not to know. He cannot explain the topic in simple words, because he himself is already so deep in the subject that he does not see where the student may stumble. This is the “curse of knowledge” in action. The teacher is irritated: “How can you not understand? It is elementary!” And the student is confused because for him it is not elementary. The teacher is not on the “peak of stupidity,” but on the “plateau of stable competence,” but he has forgotten how to descend from this plateau to beginners.

The solution in education: The best teachers and lecturers are those who remember their own “peak of stupidity.” They do not say “this is easy.” They say: “It was also difficult for me to understand this, let’s try to figure it out together.” They use metacognitive strategies: “Now check yourself — can you retell this in your own words? Can you apply this to another task?” They teach students to evaluate not their confidence, but their ability to apply knowledge.

In Everyday Life

And now turn off “professional mode” and look at your ordinary life. The Dunning-Kruger effect does not hide in conference rooms and parliaments — it lives in our kitchen, in the parking lot, in family chats, and on summer cottage plots. It is what we see every day, often without even realizing that behind it stands a powerful psychological mechanism.

The most widespread example: drivers.

Surveys show that from 70 to 90% of drivers believe that they drive better than average. Think about this figure. Statistically, it is impossible for 90% of people to be better than average. Someone must be worse. But almost each of us sincerely believes that he is a good, careful, attentive driver, and everyone else is an idiot who gets in the way on the road.

Why does this happen? Because we evaluate ourselves according to internal criteria (“I try, I am careful, I do not violate the rules”). And we evaluate others according to external signs (“This one cut me off, that one did not turn on the turn signal, those ones drive like madmen”). We do not have an objective tool to compare ourselves with others. We do not see our own mistakes because, behind the wheel, we are busy controlling the car, not observing ourselves.

We are confident in our driving skill, but we do not know what we do not know about driving. We do not know how ABS actually works, what stopping distance our car has on a wet road, how to properly recover from a skid. We simply “feel” that we will manage. And this “feeling” turns out to be an illusion as soon as a real emergency situation arises.

Example: couch experts in everything.

Sit at any family holiday or in a group of friends, and you will hear confident advice on topics that nobody understands:

• “You urgently need to buy these stocks, they will grow a hundred times!” says a person who has never read a financial report.
• “Your child sleeps badly because you ruined his schedule, you need to do this, this, and this,” says someone who has no children.
• “This film is terrible, I would have shot it better, they should have done it like this there…” says a person who has never held a camera in his hands.
• “If I were in the president’s place…” — what follows is a 10-minute lecture on how to run a country, from a person who does not know how the budget works.

We have all heard this. We have all done this. It is not because we are evil or arrogant. It is because we are on the “peak of stupidity” in this specific topic. We learned something superficially, it seemed to us that we understood it, and we feel obliged to share our “genius” thought.

The most dangerous thing in everyday life is categoricalness.

Pay attention: the more confident the advice sounds, the more often it comes from an amateur. Experts speak carefully: “On the one hand…, on the other hand…, depending on the situation…”. And amateurs speak categorically: “It is always like this!”, “Only this way and no other way!”, “Works 100%!” This is a marker of the “peak of stupidity.” The more categorical the statement, the higher the probability that its author is incompetent. Because the more you know, the more you see exceptions, nuances, context. And the harder it is for you to say “always” or “never.”

How to recognize the Dunning-Kruger effect in everyday life?

1. Ask yourself: “What do I really know about this topic, apart from general words?”
2. Check whether the person (or you) has education, experience, practice in this area. Or is this simply “an opinion based on a post that was read”?
3. Pay attention to marker words: “always,” “never,” “obvious,” “every fool knows” — this often says that a person does not know alternative points of view.
4. If you catch yourself giving confident advice in an area where you are not a professional, freeze for a second. Ask: “Do I really understand this? Or do I just want to seem smart?”

And the last, most important thing to take away from this chapter: the Dunning-Kruger effect is not about “others.” It is about us.

We are all amateurs in most areas of life. We all from time to time fall into the “peak of stupidity.” We all give advice where we are incompetent. And we all suffer from not seeing our mistakes. But this is the main task — to see. To admit that our confidence may be an illusion. To stop, listen to experts, ask questions, double-check ourselves. This is the path from the “peak of stupidity” to real wisdom. And this path begins with a simple admission: “I can be wrong.”

The Double of the Effect: Impostor Syndrome and the Polarity of Self-Assessment

Until now, we have been talking about people who overestimate themselves. About those who stand on the “peak of stupidity” and sincerely believe in their own genius while being absolute amateurs. But there is another side of the coin. There are people who suffer from the directly opposite problem — they underestimate themselves. And this problem has its own name, which sounds beautiful and tragic at the same time: “impostor syndrome.”

If the Dunning-Kruger effect is when an incompetent person thinks he is a genius, then impostor syndrome is when a competent person thinks he is a fraud.

Imagine this picture: a professor who has been teaching at a university for 30 years, has published hundreds of scientific articles, received prestigious awards, and raised dozens of students. And this professor wakes up at night in a cold sweat with the thought: “Today they will expose me. Everyone will find out that I actually know nothing. I have simply been lucky so far, I have deceived everyone, my achievements are an accident, I do not deserve my place.”

This is not a joke and not an invention. Impostor syndrome is a real psychological condition that was first described by psychologists Pauline Clance and Suzanne Imes in 1978. They studied successful women — professors, doctors, lawyers, managers — and discovered that many of them, despite outstanding achievements, live with the constant feeling that they are “impostors,” that they accidentally ended up in their place and that sooner or later their “deception” will be exposed.

Impostor syndrome spares no one. It is suffered by straight-A students who are afraid that their admission was a mistake. It is suffered by top managers who attribute their success to a “combination of circumstances” rather than to their talent. It is suffered by famous actors who, before every appearance on stage, think: “Today I will fail, everyone will understand that I am talentless.” Impostor syndrome occurs in people of all ages, all professions, and all income levels.

How does this happen? Why can a person with objectively high achievements doubt himself so painfully? The answer lies in the mechanism we have already examined — in metacognition. But here it works in the exact opposite way compared with the Dunning-Kruger effect.

A person with impostor syndrome has a hypertrophied inner critic. He sees all his mistakes, all gaps in his knowledge, all moments of uncertainty. He knows about a thousand nuances that he has not yet understood. He compares himself not with real people around him, but with the unattainable ideal of a “perfect specialist” that exists only in his head. And compared with this ideal, he seems pathetic and unworthy to himself.

He does not notice his successes. If he solved a difficult task, he thinks: “It was easy, anyone would have managed.” If he received an award, he thinks: “I was just lucky, the judges made a mistake.” If his colleagues praise him, he thinks: “They are just being polite, they do not know the whole truth.” He devalues his achievements and attributes them to external factors: luck, chance, a combination of circumstances, the fact that “the task was simple” or that “others simply did not figure it out.”

And what is most paradoxical: impostor syndrome often becomes a self-supporting mechanism. A person is afraid of being exposed, so he works even harder, spends even more energy, reaches even greater heights. And each new success only worsens his anxiety: “They think I am a genius. If they knew the truth, they would be disappointed. I need to keep pretending.” This is an endless race that exhausts and brings no satisfaction.

Characteristic of Those Who Are on the “Slope of Enlightenment”

Now let’s connect two maps: the Dunning-Kruger curve and impostor syndrome. It turns out that these two phenomena are not accidental and not independent. They have a clear geographical attachment on our competence curve.

Impostor syndrome is characteristic of those who are on the “slope of enlightenment” or at the first stages of the “plateau of stability.” This is not accidental. Think about who suffers most from the feeling “I know nothing”? The one who is just beginning and remains in blissful ignorance on the “peak of stupidity”? No, that one is generally sure that he knows everything. The one who is in the “valley of despair”? There a person also suffers, but his suffering is the acute awareness of his complete incompetence. And impostor syndrome is a more insidious state. It is when you already know enough to see the abyss, but are not yet confident enough to feel safe.

Let’s examine this dynamic in more detail.

On the “slope of enlightenment,” a person has already accumulated a lot of knowledge. He can solve complex tasks, his colleagues value him, he sees real progress. But precisely because he knows a lot, he sees how much still remains beyond the limits of his knowledge. He looks at world-class experts and compares himself with them. He sees that they know even more, and thinks: “I am nobody compared with them. My knowledge is baby talk.”

He does not see that these world experts are also people who were once in his place. He does not see that they also made mistakes, also doubted, also felt like impostors. He sees only the final result — their brilliant confidence and reputation. And he projects this picture onto himself.

At the same time, the person on the “slope of enlightenment” already has developed metacognition. His inner radar works perfectly. He sees every mistake of his, every gap, every inaccuracy. And this radar creates constant background noise: “You are not good enough. You are making mistakes. You are not worthy.” He stops noticing his victories because his brain is focused on searching for flaws.

And here is what is interesting: impostor syndrome often intensifies precisely when a person reaches a new level of success. Got a promotion? “They made a mistake, I will not cope.” Published an article? “It is weak, they will criticize me.” Received good feedback from a client? “He was just kind.” Each new level of success raises the bar of expectations and intensifies the fear of “being exposed.”

This inner conflict — “I know enough to see my flaws, but I am not confident enough to accept my strengths” — is the essence of impostor syndrome on the slope of enlightenment.

Comparison table

To fully understand these two poles of self-esteem, let’s present them in the form of a clear comparative table. This will help you see the differences and perhaps recognize yourself or someone you know in one of these portraits.

A common problem

Now that we’ve seen these two poles—overestimation and underestimation—a logical question arises: what do they have in common? Why are they “doubles”? Why are we considering them together in one chapter?

The answer is simple and deep at the same time: both distortions interfere with adequate self-assessment and personal growth.

Both the person on the “peak of stupidity” and the person with impostor syndrome live in an illusion. The first lives in the illusion of his greatness. The second — in the illusion of his worthlessness. And both of these illusions are equally far from reality.

Both of these states prevent a person from moving forward and developing.

• A person with the Dunning-Kruger effect does not develop because he thinks that he has nothing left to learn. Why read books, listen to experts, take courses, if you already “know everything” anyway? He closes the door to new knowledge and remains forever in his small world of incompetence.
• A person with impostor syndrome does develop, but with enormous effort and at the cost of his own health. He continues to learn, work, achieve — but not for pleasure or self-realization, but out of fear of being “exposed.” He does not get satisfaction from successes because he cannot own them. He spends an incredible amount of energy on anxiety and self-flagellation, not on creation.

And here is the main paradox: both of these people suffer from the same problem — from the inability to see their real self. One does not have the tools (metacognition) to see his shortcomings. The other has the tools, but they are aimed only at searching for shortcomings and ignore strengths.

But there is also good news. Understanding this polarity is already halfway to healing. When you know that these two traps exist, you can:

1. Check yourself for the “peak of stupidity”: “Am I not too confident in this topic? Does it not seem to me that I know everything, although I have only just begun to study this question? What do experts say?”
2. Check yourself for impostor syndrome: “Am I not too harsh on myself? Am I not devaluing my achievements? What do I really know how to do, what have I done, what have I achieved?”

And most importantly — learn balance. Real, adult, stable self-assessment is not “I am a genius” and not “I am a nothing.” It is calm, firm knowledge: “I am good at this, but I am not ideal. I make mistakes in this, but I am learning. I know what I know, and I know the boundaries of my knowledge. And this is normal.”

The ideal portrait is the “plateau of stable competence.” This is when you do not fall into euphoria from victory and do not fall into panic from a mistake. You simply accept yourself as a whole — with your strengths and with your areas of growth. You are not afraid to admit that you do not know something, but you are also not embarrassed to admit that you are good at something.

This is exactly the balance worth learning. Not to be an “impostor” and not to be a “guru.” To simply be an adequate, mature, competent person who knows how both to learn and to accept his achievements.

Criticism and Discussions: Is Everything Really So Unambiguous?

Until now, we have been talking about the Dunning-Kruger effect as an unshakable law of psychology, almost like the law of universal gravitation in the social sciences. And this is right — the effect has indeed become one of the most famous and cited phenomena in modern psychology.

But science is not a collection of sacred truths. Science is a living, breathing, eternally doubting organism. And any phenomenon, even the most beautiful and popular one, sooner or later faces criticism. The Dunning-Kruger effect is no exception. Moreover, a real methodological battle has flared up around it, which has been going on for more than two decades.

The main and most serious blow to the effect was struck from an unexpected side — not from the field of psychology, but from the field of statistics. Critics declared that the Dunning-Kruger effect is not a psychological phenomenon at all, but merely a statistical artifact. Or, more simply, a mathematical trick that arises because of the way researchers process data.

Let’s figure out what the essence of this criticism is, because it is not only interesting in itself, but also helps us understand the nature of self-assessment more deeply.

What Is the Problem: Regression to the Mean.

Critics pointed to one subtle but fatal methodological error in Dunning and Kruger’s original experiment. Its essence is that the researchers took people with extreme results — the weakest (the bottom quartile) and the strongest (the top quartile) — and compared their self-assessment with their real results.

And here a statistical law comes into play, which is called “regression to the mean.” This law says: if you choose a group of people with extremely low or extremely high scores, then upon repeated measurement, their results will most likely “shift” toward the average value. This is not magic; it is pure mathematics, connected with the fact that extreme results always contain a large share of randomness.

How does this work in practice in the case of the Dunning-Kruger effect?

1. The weakest participants showed very poor results. But part of this “badness” may be connected with chance: they did not get enough sleep, got distracted, did not understand the instructions, or simply had bad luck with the questions. If they were tested again, their results would most likely be slightly better (closer to the mean). But when they are asked to assess themselves, they assess not their “accidentally poor” result, but their “average” level of ability. And this assessment turns out to be higher than their real result in the experiment. The result is overestimation — the Dunning-Kruger effect.
2. The strongest participants showed very good results. But part of this “goodness” is also connected with chance: they got familiar questions, they were on a roll, they were lucky. If they were tested again, their results would most likely be slightly worse (closer to the mean). But when they are asked to assess themselves, they assess their “average” level. And this assessment turns out to be lower than their real result in the experiment. The result is underestimation — also part of the Dunning-Kruger effect.

Critics say: “Look! You do not need any psychology, any metacognition, any ‘double burden of incompetence.’ Everything you are observing is simply a mathematical trick. If you take random data and perform the same procedure with it — divide it into extreme groups and compare real results with self-assessment — you will get exactly the same picture!”

And, what is most surprising, they are right. If you take completely random numbers and process them according to the same scheme as Dunning and Kruger, you really will get a similar graph: the “worst” numbers will be overestimated, and the “best” ones will be underestimated. This is a mathematical fact that cannot be argued with.

Does This Mean That the Dunning-Kruger Effect Does Not Exist?

This is where the most interesting part begins. The answer to this question is both yes and no.

“Yes” in the sense that part of the effect, especially under experimental conditions, can indeed be explained by statistical regression. This means that perhaps Dunning and Kruger somewhat exaggerated the scale of the phenomenon. They saw a pattern that was partly “native” (psychological) and partly “introduced” (mathematical). And their critics were right to point this out.

“No” in the sense that the effect exists independently of statistical tricks. And here is why.

Dunning’s Counterarguments

When the criticism reached its peak, David Dunning did not hide behind his diploma and ignore his opponents. He and his colleagues conducted a series of additional studies to figure out whether their effect really was just statistical noise, or whether there was something real behind it.

And they presented convincing counterarguments that restored the effect’s scientific weight.

Counterargument One: the effect remains even when independent indicators of competence are used.

In the original study, Dunning and Kruger asked people to assess their skills in the very same area in which they were tested (logic, grammar, humor). Critics said: “You simply created an artificial situation. People cannot assess their results because they do not know how to assess them. In real life, people assess themselves better.” Dunning answered: “Fine, let’s check in real life.”

They conducted studies in which they assessed how well people in real life (and not in a laboratory) knew, for example, geography or politics. And what did they find? Those who knew the least still overestimated their knowledge. They sincerely thought that they knew where a particular country was located, or that they understood political processes, although objectively their knowledge was at a schoolchild’s level. The effect persisted.

Moreover, Dunning went further. He and his colleagues conducted a study in which people were assessed by other people, not by tests. For example, they asked students to assess how well their classmates understood mathematics, and then checked their real grades in mathematics. And what did they see? The weakest students overestimated themselves in the eyes of other people. They sincerely thought that they appeared competent to others, although in reality others saw their weakness. And vice versa, the strongest students underestimated how others perceived them.

These experiments showed that the effect does not disappear if the “statistical artifact” is removed. It persists under different conditions, with different tasks, with different methods of measurement. This indicated that there was something real behind the phenomenon, and not simply mathematical randomness.

Counterargument Two: studies with large samples (more than 3,500 people) confirm the metacognitive explanation.

To finally dispel doubts, Dunning and his colleagues conducted a large-scale study with a huge sample — more than 3,500 people. These were people of different ages, professions, and levels of education. They took tests and assessed themselves.

And here is what the results showed: even in such a large sample, where the effect of regression to the mean should have “smoothed out” (because randomness averages out), the effect persisted. The most incompetent people systematically overestimated themselves, and the most competent systematically underestimated themselves.

Moreover, the researchers used special statistical methods that correct for the effect of regression to the mean. They literally “subtracted” the mathematical component from the data to see whether the psychological component would remain. And it remained. The gap between self-assessment and reality was real, not illusory.

Counterargument Three: the effect appears not only in the assessment of “me vs others,” but also in absolute self-assessment.

Critics said: “People simply assess their place in the group incorrectly because they do not know how others performed. But they may be able to correctly assess how many correct answers they gave in absolute terms.” Dunning checked this too.

He asked participants to assess the absolute number of correct answers they had given (for example, “How many tasks out of 20 did you solve correctly?”). And again: the weakest participants significantly overestimated the number of correct answers. They thought they had solved 15 out of 20, when in fact they had solved 5. They simply did not know what a “correct answer” was and thought that their erroneous solutions were correct. The effect persisted in absolute assessment as well.

Thus, Dunning convincingly showed that although statistical regression can indeed explain part of the effect, it does not explain it completely. Behind the phenomenon there is a real psychological mechanism — the lack of metacognitive skills among the incompetent and hypertrophied metacognition among the competent.

A Nuance That Is Often Missed

But even after all the counterarguments and mathematical clarifications, one extremely important nuance remains, which is most often missed in popular articles, memes, and conversations about the Dunning-Kruger effect. And this nuance radically changes how we should understand and apply this phenomenon in life.

The nuance: the Dunning-Kruger effect is not about “stupid people.” It is about all of us in situations where we are incompetent.

On the internet and in everyday consciousness, the Dunning-Kruger effect often turns into a weapon. It is used to point a finger at an opponent: “You just have the Dunning-Kruger effect! You think you are smart, but in reality you are a fool!” This turns the phenomenon into a label, into a way of humiliation.

But this is an absolutely incorrect and harmful use.

Let’s remember the essence of the effect. It appears when a person is in an area where he is incompetent. And each of us has hundreds of such areas. You can be a brilliant physicist, but a complete amateur in cooking. You can be an outstanding surgeon, but understand nothing about cars. You can be a talented writer, but get lost in financial questions.

And when you enter any of these “foreign” areas, you automatically become a potential candidate for the “peak of stupidity.” You will overestimate your knowledge because you have no standard. This does not make you a “stupid person.” It makes you a person who has just begun to understand a new topic.

The same applies to impostor syndrome. You may be a recognized expert in your field, but when you face a new, more complex task, you may feel like an “impostor.” This does not make you a “modest genius” or a “true professional.” It makes you a person who realizes the scale of complexity.

The second most important nuance: this is not a permanent state. It changes with learning and experience.

The Dunning-Kruger effect is not glued to a person forever. It is not a “personality type.” It is a situational reaction to the level of knowledge in a specific area.

A person who today is on the “peak of stupidity” in programming (he wrote “Hello, World!” and considers himself a hacker) tomorrow, after a month of intensive learning, will slide into the “valley of despair” (he tried to write a real application and realized that he knows nothing). And in a year he may find himself on the “slope of enlightenment,” and in three — on the “plateau of stable competence.” The same person, in the same area, but at different stages — and his self-assessment changes radically.

This means that no one is protected from the Dunning-Kruger effect at any moment of their life. And this is normal! We cannot be experts in everything. We constantly enter new areas — master a new profession, a new hobby, a new language, new relationships. And each time we go through this path: from a self-confident beginner to a modest student, and then, if we are lucky, to a confident master.

That is exactly why it is important not to use the Dunning-Kruger effect as a label, but to use it as a tool for self-knowledge and compassion.

• A tool for self-knowledge: “Aha, I feel very confident in this question. Perhaps I am on the ‘peak of stupidity’? Maybe I should check my knowledge, read experts, ask questions?”
• A tool for compassion: “This person is aggressively confident that he is right and does not listen to others. Perhaps he is simply on the ‘peak of stupidity’ in this topic. He is not evil and not stupid — he simply does not know what he does not know. Maybe I can help him see this with kindness, not with judgment?”

And when we stop using the Dunning-Kruger effect as a club for beating opponents and begin using it as a mirror for self-reflection, it becomes not just an interesting psychological fact, but a powerful tool for personal growth. It reminds us of our shared human vulnerability: all of us, absolutely all of us, are sometimes blind to our blindness. And it is precisely this awareness that makes us wiser, more tolerant, and more open to learning.

How to Overcome the Dunning-Kruger Effect: A Practical Guide

We have examined the mechanics, considered examples, discussed the criticism. Now comes the most important moment — practice. What should be done? How not to become a victim of your own brain? How to protect yourself from the insidious traps of self-assessment and at the same time not slide into impostor syndrome?

I have good news for you: the Dunning-Kruger effect can not only be realized, but also successfully bypassed. For this, you do not need superpowers or years of psychotherapy (although it sometimes helps). All you need are simple, concrete, everyday habits that you can begin to introduce today.

Here is a step-by-step instruction for those who want to get out of the trap of unconscious incompetence and not remain stuck in it forever.

Regularly Check Your Knowledge with Objective Tests

The most important thing to understand is this: your inner feeling (“I feel that I know”) and objective reality (“I can really apply this in practice”) are two different things. And they very often do not coincide. Your brain loves to create the illusion of understanding: you read an article, hear familiar terms, and it seems to you that you are “in the know.” But this feeling is deceptive.

What to do in practice:

• Do not trust your intuition, check it. If you are studying a new topic, do not ask yourself: “Do I feel confident?” Instead, ask: “Can I answer test questions on this topic?” Find tests, quizzes, practical assignments, and check yourself. Do not look at the answers in advance. Try to solve the task from scratch. If you cannot — you do not know. Period.
• Example from life: You are studying a foreign language. You have learned 50 new words and feel like a good fellow. Instead of rejoicing in the illusion, close the textbook and try to write a dictation using these words or compose 10 sentences with them. If you stumble, make mistakes, confuse articles — it means you do not know yet. This is not a failure, this is diagnostics. This is your map of what needs to be learned next.
• Use the principle of “active recall.” This is one of the most effective learning methods proven by science. Instead of rereading the material (this creates a false feeling of familiarity), close the book and try to recall everything you have just read in your own words. Write it down. Then open the book and check. The difference between what you “remembered” and what was written is your real lack of knowledge.

Seek Feedback from Competent People

The Dunning-Kruger effect is, in essence, the effect of “the absence of a mirror.” You cannot see your mistakes because you have no external reference point. You need someone who knows more than you and can honestly, but kindly, point out your blind spots.

What to do in practice:

• Find a mentor or adviser. This does not necessarily have to be an official “guru.” It can be a colleague with more experience, a teacher, a friend who understands the topic better than you. Regularly show him your work, ask questions, ask for criticism.
• Do not be afraid to look stupid. The biggest mistake of people on the “peak of stupidity” is the fear of showing their incompetence. They avoid questions, pretend that they understand everything, and thereby close off access to real learning for themselves. A real student is the one who asks “stupid” questions. Because he knows: there are no stupid questions, there are only stupid answers that you avoid out of pride.
• Ask for specific, not general, feedback. Do not ask: “So how is it? Is it normal?” This is useless. Ask: “What exactly can I improve in this section? Where did I make a logical mistake?” The more specific your request, the more useful the answer will be.
• Learn to accept criticism without defending yourself. This is the most difficult point because criticism hits our ego. But remember: criticism is not an attack on you as a person. It is information about how to improve your product, your skill, your knowledge. If you feel that you are beginning to defend yourself and justify yourself, pause. Say: “Thank you, I will think about this.” And really think about it.

Analyze Your Mistakes Instead of Ignoring Them

Mistakes are not a failure. Mistakes are data. They are your personal textbook, written by life itself. But only under one condition: if you analyze them. If you simply brush off mistakes (“Well, it happens,” “Everyone makes mistakes”), you miss a golden opportunity for growth.

What to do in practice:

• Keep a “mistake diary.” This can be a notebook, a note on your phone, a document in the cloud. Write down every mistake you have made in the field you are studying, and, most importantly, why you made it. Not simply “I made a mistake in the calculation,” but “I made a mistake in the calculation because I confused the order of operations. Next time I will check the order of operations first.”
• Conduct a “debriefing.” Once a week or once a month, return to your mistake diary and look: which mistakes repeat themselves? What is the systemic problem? What do I need to improve in order to stop making this mistake?
• Mark not only mistakes, but also “successful” mistakes. Sometimes a mistake leads you to an unexpected insight or a new solution. Mark such cases too. This helps you stop being afraid of mistakes and begin using them as a creative resource.

Develop Metacognitive Skills: Ask Yourself the Question “Where Do I Know This From?”

This is the most powerful exercise of all. This is your personal shield against self-deception. You can develop the habit of constantly doubting the reliability of your own knowledge — not destructively, but constructively.

What to do in practice:

• Every time you assert something, stop for a second and ask yourself: “Where do I know this from?” If the answer is: “Well, I read it on the internet,” “It seems to me,” “I think so,” “Everyone says so” — this is a red flag. This is a signal that your knowledge is superficial.
• If the answer is: “I checked this in three independent sources,” “I conducted the experiment myself,” “I can explain the logic of this statement step by step,” — your knowledge has a foundation beneath it.
• Use the “rule of three sources.” Before forming a firm opinion on a complex question, find three different, independent sources of information, preferably with different points of view. Compare them, find contradictions, ask questions. This will protect you from information bubbles.
• Practice “teaching.” One of the best ways to check whether you really know something is to try to explain it to another person. If you can explain a complex concept in simple words so that a 10-year-old child understands it, you really understood it. If you begin to get confused, use complex terms that you yourself cannot decipher, you have not understood it yet.

Learn in Areas Where You Feel Uncertain — This Is the Zone of Growth

One of the most dangerous strategies in life is to remain only in the comfort zone, never trying anything new. We love doing what we are good at. It is pleasant, it raises self-esteem, it is safe. We get used to this state like to an old, cozy armchair. We know every turn there, every difficulty, we feel like masters of the situation. But if we never go beyond the limits of this armchair, we stop growing. New skills, new knowledge, new horizons remain closed to us.

But here a critically important caveat is needed, which is often missed.

In modern psychology and neuroscience, the rigid imperative “Leave your comfort zone — it is always useful” has long been abandoned. Such an approach can be not only useless, but also harmful, especially for people with anxiety, perfectionism, impostor syndrome, or in a state of chronic stress.

Why is this so:

• The comfort zone is not an “enemy,” it is your resource. It is a place where you restore your strength, feel safe, accumulate energy. If you are constantly under stress from “the new and difficult,” your nervous system becomes exhausted. The result is not growth, but burnout, anxiety, and the desire to do nothing at all.
• Stress can be different. There is “good” stress (eustress) — short-term tension that mobilizes and ends with success and satisfaction. And there is “bad” stress (distress) — chronic, unbearable, which destroys the body. Your task is to be in the zone of productive tension, not in the zone of panic.
• Leaving the comfort zone must be voluntary and dosed. No one is saying: “Jump with a parachute and it will upgrade you if you are afraid of heights.” If you are afraid of public speaking, you do not need to speak in front of an audience of a thousand people right away. You can start by telling a joke in a circle of three friends. In small steps.

What to do in practice (taking these caveats into account):

• Use the concept of the “zone of proximal development.” This is not the zone of panic and not the zone of boredom. This is a task that is slightly above your current level. One that you cannot solve immediately, but can solve with a little effort, with a hint, with a mistake that can be corrected. If the task causes horror and paralysis in you, you have gone too far; take one step back.
• Start with the small, not with the grandiose. Want to learn to cook? Do not immediately take on a Napoleon cake or Peking duck. Start with scrambled eggs or a simple soup. Want to learn a language? Start with 5 minutes a day, not with a 300-page textbook. Small victories strengthen confidence; big failures destroy it.
• Listen to yourself, not to external slogans. If you feel scared, uncomfortable, and sick at the thought of a new task, this is not a “zone of growth,” this is a “zone of trauma.” Perhaps you need more time to prepare, more resources, more support. Or perhaps this task is simply not for you right now — and that is normal. Not all “exits from the comfort zone” are mandatory. You have the right to choose what and when to learn.
• Alternate “challenges” and “rest.” It is impossible to constantly be in a state of learning. After every significant effort, give yourself time to “roll back” into the comfort zone, recover, digest the experience. It is like in sports: muscles grow not during training, but during rest after it. The psyche works exactly the same way.
• Learn in areas that are really interesting to you. You are not obliged to become an expert in everything. If you do not like programming, do not learn it only because “it is useful.” Find what lights you up. In an interesting topic, even “leaving the comfort zone” feels like an adventure, not like hard labor.

The main principle of modern psychology of growth:

Not “leave your comfort zone at any cost,” but “expand your comfort zone gradually, with care for yourself.”

This is not about a leap. It is about taking a small step toward the unknown with curiosity and caution, stopping in time and giving yourself rest. Such an approach does not traumatize the psyche, but strengthens it. It makes you not “hardened and enduring” at the cost of a nervous breakdown, but stable and flexible — capable both of new challenges and of calm rest.

For Managers and Teachers: How to Work with Someone Else’s Effect

If you are responsible for other people — manage a team, teach, raise children — you face an even more difficult task. You need not only to protect yourself from the Dunning-Kruger effect, but also to help other people get out of its trap. And to do this in such a way as not to humiliate them and not make them defend themselves.

Here are practical principles for working with someone else’s incompetent confidence.

Give Clear, Measurable Criteria for Success

One of the main reasons why people end up on the “peak of stupidity” is the vagueness of criteria. They do not know “how it should be done correctly” because no one has explained it to them. Their self-assessment is built on feelings, not facts. Your task is to give them facts.

What to do in practice:

• Create a “frame” for evaluation. Instead of abstract phrases (“Do it well,” “Be professional”), use specific, verifiable criteria. For example, not “Write a good report,” but “The report must contain the following sections: introduction, data analysis, conclusions, recommendations. Length — no more than 5 pages. Use at least three data sources.”
• Show examples. Give the person an example of “good work.” Show what “done correctly” means. This gives him a standard for comparison, that very “external standard” he lacked.
• Clearly mark the boundaries. Explain what is an acceptable margin of error and what is a critical mistake. When a person knows where the “red line” is, it is easier for him to assess his results.

Hold Regular One-on-One Meetings with Feedback

Feedback should not be a one-time event (when everything has already burned down and it is necessary to “debrief”), but a regular process. People should get used to receiving information about their work and stop perceiving it as a threat.

What to do in practice:

• Schedule regular short meetings. For example, once a week or once every two weeks for 15–20 minutes. Discuss not only the final result, but also the process.
• Use the “sandwich” rule with caution. The classic advice “say something good first, then criticism, then something good again” is often perceived as manipulation. It is better to use the “Situation — Action — Impact” model: describe the specific situation, the specific behavior of the person, and the specific impact of this behavior on the result. Without evaluations of “good” or “bad,” only facts. Example: “Last week (situation), in the report you used unverified data (action). This led to the fact that we made a decision based on unreliable information (impact). Let’s think about how we can check data next time.”
• Ask, do not only speak. Ask questions: “How do you assess your work yourself? What did you do best? What was difficult? Where do you see areas for improvement?” This develops a person’s metacognitive skills.

Do Not Encourage Confidence, Encourage Accuracy and Reflection

This is the most difficult and most important point for any manager. In most cultures, especially corporate ones, we unconsciously encourage confidence. We like people who speak loudly, categorically, with aplomb. We take them for leaders. And we often do not notice modest, doubting, reflective people or even consider them “weak.”

But if you are a manager who wants to develop competence, not just “loud voices,” you must rebuild the reward system.

What to do in practice:

• Praise not for “confidence,” but for “accuracy.” Note those who give accurate forecasts, who argue their decisions with data, who admit their mistakes and learn from them. Do not encourage “briskness” and “self-confidence” if they are not backed up by real results.
• Create a culture of “safe admission of mistakes.” When a person admits a mistake, do not scold him. On the contrary, thank him for his honesty and together examine what went wrong. If you punish mistakes, people will hide them and get stuck on the “peak of stupidity.” If you encourage analysis of mistakes, people will learn faster.
• Ask “provocative” questions. Instead of immediately making a decision, ask: “What if we are wrong? What alternative options are there? What arguments might the opponent have?” This accustoms the team to reflection and reduces the risk of self-confident decisions.
• Lead by personal example. The most effective thing is when the manager himself says: “I am not sure about this question, let’s ask the expert,” or “I was wrong in this decision, here is how I understood it and what I will do differently.” This gives the whole team permission to be imperfect and to learn.

The Main Recipe

And at the end of this practical guide, I will give you the most important recipe, which unites everything said above. It is simple, but it is precisely the hardest one to carry out.

The Dunning-Kruger effect is overcome in only one way — real deepening into the topic. The more you know, the more accurately you assess what you do not know.

There is no magic pill. There are no shortcuts. The only way to get off the “peak of stupidity” and go through the “valley of despair” to the “slope of enlightenment” is to continue learning. Persistently, patiently, regularly, despite disappointment, shame, boredom, and fear.

Here is what “real deepening” means:

• Read not superficial articles, but fundamental books. Study not only the “tops,” but also the “roots.” Learn the history of the question, alternative theories, complex cases.
• Practice systematically. Not “when there is a mood,” but a little every day. Learning a language is not two hours on Saturday, but 15 minutes every day. Music is not “I will play when I have time,” but 20 minutes of daily scales.
• Communicate with those who know more than you. Go to conferences, interest clubs, professional communities. Listen, ask questions, absorb. An environment of expert people is the best catalyst for growth.
• Review your old work. Take what you did a year ago and look at it with fresh eyes. If you see mistakes, it means you have grown. If you see a masterpiece, it means you are stuck on the “peak of stupidity.”

And remember: the more you learn, the more you realize how much you still have to learn. This is not disappointment; it is a sign that you are on the right path. It is a sign that you have moved from “unconscious incompetence” to “conscious incompetence,” and from there, with persistence and time, to “conscious competence.”

No one becomes an expert in one day. But everyone who does not give up in the “valley of despair” one day reaches the “plateau of stability.” And this plateau is worth it.

Conclusion and Main Takeaway

And now — the most important thing. The thing for which I wrote all of this. One thought that is worth all the pages, all the examples, and all the exercises.

Here it is:

The path from “I know everything” to “I cannot do anything” is not a sentence, not a failure, and not a diagnosis. It is the normal, natural, inevitable trajectory of any learning. Every time you begin something new, you go through this path again. And there is nothing shameful in this.

Think about these words.

When you feel confident in a new topic — it is not because you are a genius. It is because you are on the “peak of stupidity.” And this is normal. This is your biological “bumper” that gives you the courage to begin.

When you fall into the “valley of despair” and feel like a complete nothing — it is not because you are hopeless. It is because you have finally seen the real picture. This is not a step backward, it is a giant step forward. It is a moment of awakening.

When you slowly, with difficulty, climb the “slope of enlightenment” — it is not because you are stupid. It is because you are growing. Every new skill, every new piece of knowledge is a little brick that you place in the foundation of your competence.

When you reach the “plateau of stability” — this is not the finish line. It is simply a new point of support from which you can set off on a new journey, begin a new task, enter a new field, and go through this whole path again.

And this is the main wisdom. You are not obliged to be an expert in everything. You are not obliged to know the answers to all questions. You are not obliged to be confident always and everywhere. You have the right to be a beginner. You have the right to make mistakes. You have the right not to know. You have the right to doubt.

But you also have an obligation — to yourself. Not to get stuck on the “peak of stupidity.” Not to give up in the “valley of despair.” To continue moving forward. To learn. To ask. To listen. To try again. And again. And again.

The Final Question for You

And now, when you have read this article to the very end, I want to ask you one question. Do not rush to answer. Feel it. Give yourself time to think.

In what area of your life are you now on the “peak of stupidity”? And are you ready to descend into the “valley of despair” so that one day you can rise to real wisdom?

This is a difficult question. Because an honest answer to it requires courage. The courage to admit that perhaps you are too confident in something that, in reality, you understand nothing about. The courage to admit that your categoricalness is not strength, but blindness. The courage to admit that you still have a lot to learn.

But this very admission is the first step. The most important step. The step that separates a person who will learn and grow from a person who will remain on the “peak of stupidity,” confident in his own rightness until the end of his days.

What does it mean to “descend into the valley of despair” in your life?

It means:

• Instead of giving advice, start asking questions.
• Instead of teaching others, start learning yourself.
• Instead of defending your point of view, start looking for alternatives.
• Instead of pretending that you know everything, admit: “I do not know. But I want to know.”
• Instead of hiding your mistakes, start analyzing them.
• Instead of being afraid to look stupid, start asking “stupid” questions.

Yes, it is scary. It is uncomfortable. It is painful for pride. But it is precisely there, in this pain and in this fear, that real growth is born. It is precisely there, in the “valley of despair,” that you stop being a naive beginner and become a student. And a student is the one who will one day become a master.

And one more question, no less important:

In what area do you feel like an “impostor”? Where you actually already know a lot and can do a lot, but are afraid to admit it?

Because perhaps you are already standing on the “plateau of stability,” but your inner critic does not let you see it. Perhaps it is time to stop devaluing your achievements and start accepting them. To recognize that you have the right to your success. That you have earned it. That you are not a fraud, but a professional.

The Final Thought:

The Dunning-Kruger effect is not an enemy. It is a teacher. It shows us our blind spots, points to our weak places, suggests where we need to grow. It reminds us of our shared human vulnerability. And it gives us a map by which we can walk the path from ignorance to wisdom.

But a map is only a map. The path must be walked by oneself.

And this path begins with one simple, but most difficult phrase.

The phrase we are so afraid to say.

The phrase that opens doors.

“I do not know.”

Say it to yourself today. Say it to others. And you will see how the world around you begins to change. How people will begin to reach out to you, how they will begin to respect you for your honesty, how you will begin to learn faster and more deeply than ever before.

Because only the one who admits his ignorance is capable of truly knowing.
