Whether we talk about those in the corporate sphere or people who talk about social or political issues without having a solid grounding of the subject, individuals demonstrating the Dunning-Kruger effect will be unaware that their knowledge and skills are less complete than they think.
The classic test of the Dunning-Kruger Effect, as performed by Dunning and Kruger themselves, was an examination of the self-assessment skills of undergraduate psychology students.
These self-assessments were then compared to objective tests of their logical reasoning, grammar, and humor. It was found that highly skilled students underestimated their capacities while less skilled students overestimated their own capacity.
Four different studies were conducted, and in each, those in the bottom 12 th percentile of the study group assessed their own skills in the top 38 th percent.
One of the key considerations of the Dunning-Kruger effect is that it requires a certain degree of knowledge and awareness to accurately self-assess.
This same knowledge and awareness is what is required to perform well. So, poor performance in a certain sphere will accompany the lack of awareness about what is needed for achievement and excellent in that sphere.
However, by refining our skills and learning more about a particular area, we are better able to see where we went wrong and perform more effectively in the future.
At the same time, we will be better able to see where this knowledge has been lacking and self-assess. Finally, we will be able to see how our previous knowledge has been lacking, and project this forward into the future, recognizing that even future learning will not give us a comprehensive and unassailable understanding of any given topic.
The most important aspect to remember about this is that the Dunning-Kruger effect is not the province of a few, less skilled or intelligent individuals.
Every single person in the world is subject to this effect. We all have some areas where we are knowledgeable and other areas where we are relatively inexperienced or uninformed.
When people do not recognize their own mental illness, this is known as "anosognosia"; this is common for people with bipolar disorder or schizophrenia.
The inverse also applies: the unusually competent people tend to underestimate their ability compared to others; this is known as impostor syndrome.
The Dunning-Kruger effect is a slightly more specific case of the bias known as illusory superiority , where people tend to overestimate their good points in comparison to others around them, while concurrently underestimating their negative points.
The effect has been shown by experiment in several ways, but in this case Dunning and Kruger tested students on a series of criteria such as humour , grammar, and logic and compared the actual test results with each student's own estimation of their performance.
Those who scored well on these tests were shown, consistently, to underestimate their performance. This can be explained as a form of psychological projection : those who found the tasks easy and thus scored highly mistakenly thought that they would also be easy for others.
This is similar to the aforementioned "impostor syndrome" — found notably in graduate students and high-achieving women — whereby high achievers fail to recognize their talents as they think that others must be equally good.
Those who scored lowest on the test were found to have "grossly overestimated" their scores, thus displaying what became known as the Dunning-Kruger effect.
And what about the underachievers who overestimated their performance? In the words of Dunning and Kruger:. This overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it.
The original study was focused specifically on competence , as opposed to intelligence — Dunning and Kruger were more concerned with the empirical , measurable factors of how well a person could perform a task even "simple" or "stupid" tasks and that person's perception of how they performed that task, rather than the more nebulous concept of comparative " intelligence " or " education.
Dunning-Kruger-Effekt bezeichnet die kognitive Verzerrung im Selbstverständnis inkompetenter Menschen, das eigene Wissen und Können zu überschätzen.
Der Begriff geht auf eine Publikation von David Dunning und Justin Kruger im Jahr zurück. Die beiden Sozialpsychologen hatten in vorausgegangenen Studien bemerkt, dass etwa beim Erfassen von Texten, beim Schachspielen oder Autofahren Unwissenheit oft zu mehr Selbstvertrauen führt als Wissen.
In this convention, negative numbers signify erring toward underconfidence, positive numbers signify erring toward overconfidence, and zero signifies accurate self-assessment.
A study by Joyce Ehrlinger  summarized the major assertions of the effect that first appeared in the seminal article and continued to be supported by many studies after nine years of research: "People are typically overly optimistic when evaluating the quality of their performance on social and intellectual tasks.
In particular, poor performers grossly overestimate their performances". The effect asserts that most people are overconfident about their abilities, and that the least competent people are the most overconfident.
Support for both assertions rests upon interpreting the patterns produced from graphing the paired measures,. The most common graphical convention is the Kruger—Dunning-type graph used in the seminal article.
Researchers adopted that convention in subsequent studies of the effect. Additional graphs used by other researchers, who argued for the legitimacy of the effect include y — x versus x cross plots  and bar charts.
Recent researchers who focused on the mathematical reasoning  behind the effect studied 1, participants' ability to self-assess their competence in understanding the nature of science.
These researchers graphed their data in all the earlier articles' various conventions and explained how the numerical reasoning used to argue for the effect is similar in all.
When graphed in these established conventions, the researchers' data also supported the effect. Had the researchers ended their study at this point, their results would have added to the established consensus that validated the effect.
To expose the sources of the misleading conclusions, the researchers employed their own real data set of paired measures from 1, participants and created a second simulated data set that employed random numbers to simulate random guessing by an equal number of simulated participants.
The simulated data set contained only random noise, without any measures of human behavior. The researchers   then used the simulated data set and the graphical conventions of the behavioral scientists to produce patterns like those described as validating the Dunning—Kruger effect.
They traced the origin of the patterns, not to the dominant literature's claimed psychological disposition of humans, but instead to the nature of graphing data bounded by limits of 0 and and the process of ordering and grouping the paired measures to create the graphs.
These patterns are mathematical artifacts that random noise devoid of any human influence can produce. They further showed that the graphs used to establish the effect in three of the four case examples presented in the seminal article are patterns characteristic of purely random noise.
These patterns are numerical artifacts that behavioral scientists and educators seem to have interpreted as evidence for a human psychological disposition toward overconfidence.
But the graphic presented on the case study on humor in the seminal article  and the Numeracy researchers' real data  were not the patterns of purely random noise.
Although the data was noisy, that human-derived data exhibited some order that could not be attributed to random noise. The researchers attributed it to human influence and called it the "self-assessment signal".
The researchers went on to characterize the signal and worked to determine what human disposition it revealed. To do so, they employed different kinds of graphics that suppress or eliminate the noise responsible for most of the artifacts and distortions.
The authors discovered that the different graphics refuted the assertions made for the effect. Instead, they showed that most people are reasonably accurate in their self-assessments.
About half the 1, participants in their studies accurately estimated their performance within 10 percentage points ppts. All groups overestimated and underestimated their actual ability with equal frequency.
The Dunning-Kruger effect is also related to difficulties with metacognition, or the ability to step back and look at one's own behavior and abilities from outside of oneself.
People are often only able to evaluate themselves from their own limited and highly subjective point of view. From this limited perspective, they seem highly skilled, knowledgeable, and superior to others.
Because of this, people sometimes struggle to have a more realistic view of their own abilities. Another contributing factor is that sometimes a tiny bit of knowledge on a subject can lead people to mistakenly believe that they know all there is to know about it.
As the old saying goes, a little bit of knowledge can be a dangerous thing. A person might have the slimmest bit of awareness about a subject, yet thanks to the Dunning-Kruger effect, believe that he or she is an expert.
Other factors that can contribute to the effect include our use of heuristics , or mental shortcuts that allow us to make decisions quickly, and our tendency to seek out patterns even where none exist.
Our minds are primed to try to make sense of the disparate array of information we deal with on a daily basis. As we try to cut through the confusion and interpret our own abilities and performance within our individual worlds, it is perhaps not surprising that we sometimes fail so completely to accurately judge how well we do.
So who is affected by the Dunning-Kruger effect? Unfortunately, we all are. This is because no matter how informed or experienced we are, everyone has areas in which they are uninformed and incompetent.
You might be smart and skilled in many areas, but no one is an expert at everything. The reality is that everyone is susceptible to this phenomenon, and in fact, most of us probably experience it with surprising regularity.
People who are genuine experts in one area may mistakenly believe that their intelligence and knowledge carry over into other areas in which they are less familiar.
A brilliant scientist, for example, might be a very poor writer. In order for the scientist to recognize their own lack of skill, they need to possess a good working knowledge of things such as grammar and composition.
Because those are lacking, the scientist in this example also lacks the ability to recognize their own poor performance. The Dunning-Kruger effect is not synonymous with low IQ.
As awareness of the term has increased, its misapplication as a synonym for "stupid" has also grown.
