Dunning Krueger Effekt Why do we believe we are good at something when we actually aren’t? VideoWhy incompetent people think they're amazing - David Dunning
A lot of the time, we lack the self-awareness to notice about ourselves what we so easily notice about others.
Thinking about and questioning yourself takes time and energy. So, assumptions about our competence in certain situations could be a shortcut to solving them quickly.
Another reason why we sometimes experience the Dunning-Kruger effect is that it protects our self-esteem.
No one likes feeling bad about themselves — and realizing that we are bad at something can have this effect because it may suggest that we lack intelligence.
This response can be conscious or subconscious. It has been suggested that our mind creates a natural defense to respond in this way to these situations that we can be unaware of.
When we think we are at our best is sometimes when we are at our objective worst. That being said, we should be aware of the Dunning-Kruger effect because of the negative influence it can have over our decision-making.
But if someone is unaware of their shortcomings, they make such decisions irrespective of the negative implications they will likely have.
Moreover, because people subjected to the Dunning-Kruger effect are confident in their abilities, significant resources and energy can be invested in the success they believe that poorly informed decision will bring.
This is less than ideal at best and dangerous at worst. Consider the scenario in which a young driver is so confident in their driving abilities that they decide to go on the highway in the midst of a dangerous snowstorm.
It is also worth noting that overconfidence usually does not bode well with others— especially if it is misplaced.
Dunning and Kruger suggest that the overestimation of our competence is greatest when we have a narrow understanding of a topic.
Our confidence finds its lowest point when we have no understanding, but trails down from its mistaken peak when we gain a fuller understanding that reveals the gaps in our knowledge.
Here, we display a lower, but more realistic level of confidence in our abilities. As we gain expertise, we also gain confidence — but now it is well placed.
Indeed, experts should display a high degree of confidence in their ability because they usually truly are capable.
This chart demonstrates the U-shaped relationship between confidence and competence that characterizes the Dunning-Kruger effect.
But what does this have to do with avoiding the potentially damaging implications of the Dunning-Kruger effect? Well, if our perceived ability of a subject is brought inline with our actual ability through increased knowledge, then one strategy would seem to be deepening our understanding.
Rather than assuming you know all there is to know about a topic, explore it further. As you have a better grasp on a subject, you will probably realize there is still much to learn.
Another strategy is to ask other people to evaluate your performance. Remember, we often struggle to consider ourselves from an outside.
As Charles Darwin wrote in his book The Descent of Man , "Ignorance more frequently begets confidence than does knowledge. This phenomenon is something you have likely experienced in real life, perhaps around the dinner table at a holiday family gathering.
It may be plainly evident to everyone in the room that this person has no idea what he is talking about, yet he prattles on, blithely oblivious to his own ignorance.
The effect is named after researchers David Dunning and Justin Kruger, the two social psychologists who first described it.
In their original study on this psychological phenomenon, they performed a series of four investigations. People who scored in the lowest percentiles on tests of grammar, humor, and logic also tended to dramatically overestimate how well they had performed their actual test scores placed them in the 12th percentile, but they estimated that their performance placed them in the 62nd percentile.
In one experiment, for example, Dunning and Kruger asked their 65 participants to rate how funny different jokes were.
Some of the participants were exceptionally poor at determining what other people would find funny—yet these same subjects described themselves as excellent judges of humor.
Incompetent people, the researchers found, are not only poor performers, they are also unable to accurately assess and recognize the quality of their own work.
This is the reason why students who earn failing scores on exams sometimes feel that they deserved a much higher score. They overestimate their own knowledge and ability and are incapable of seeing the poorness of their performance.
Low performers are unable to recognize the skill and competence levels of other people, which is part of the reason why they consistently view themselves as better, more capable, and more knowledgeable than others.
This effect can have a profound impact on what people believe, the decisions they make, and the actions they take. In one study , Dunning and Ehrlinger found that women performed equally to men on a science quiz, and yet women underestimated their performance because they believed they had less scientific reasoning ability than men.
The researchers also found that as a result of this belief, these women were more likely to refuse to enter a science competition. Dunning and his colleagues have also performed experiments in which they ask respondents if they are familiar with a variety of terms related to subjects including politics, biology, physics, and geography.
Along with genuine subject-relevant concepts, they interjected completely made-up terms. In one such study, approximately 90 percent of respondents claimed that they had at least some knowledge of the made-up terms.
Consistent with other findings related to the Dunning-Kruger effect, the more familiar participants claimed that they were with a topic, the more likely they were to also claim they were familiar with the meaningless terms.
As Dunning has suggested, the very trouble with ignorance is that it can feel just like expertise. So what explains this psychological effect?
Are some people simply too dense, to be blunt, to know how dim-witted they are? Dunning and Kruger suggest that this phenomenon stems from what they refer to as a "dual burden.
Incompetent people tend to:. Dunning has pointed out that the very knowledge and skills necessary to be good at a task are the exact same qualities that a person needs to recognize that they are not good at that task.
So if a person lacks those abilities, they remain not only bad at that task but ignorant to their own inability. Dunning suggests that deficits in skill and expertise create a two-pronged problem.

Are you ever overly optimistic when planning your day? In the grammar study, for instance, 84 Cornell undergraduates were asked to complete a test evaluating their knowledge of American Standard Written English ASWE.
They were then asked to rate their own grammar ability and test performance. Those who scored lowest on the test 10th percentile tended to drastically overestimate both their perceived grammar ability 67th percentile and test score 61st percentile.
In contrast, those who scored highest on the test tended to underestimate their ability and test score.
In the decades since this study was published, numerous other studies have reproduced similar results. The Dunning-Kruger effect has been documented in domains ranging from emotional intelligence and second-language acquisition to wine knowledge and the anti-vaccination movement.
Imagine taking a multiple-choice test on a topic you know next to nothing about. You read the questions and choose the answer that seems the most reasonable.
How can you determine which of your answers are correct? Psychologists call the ability to evaluate knowledge — and gaps in knowledge — metacognition.
Our brains are hardwired to look for patterns and take shortcuts, which help us to quickly process information and make decisions.
Often, these same patterns and shortcuts lead to biases. Most people have no trouble recognizing these biases — including the Dunning-Kruger effect — in their friends, family members, and co-workers.
But the truth is that the Dunning-Kruger effect affects everyone, including you. No one can claim expertise in every domain.
You might be an expert in a number of areas and still have significant knowledge gaps in other areas.
