Warum haben oft gerade inkompetente Menschen das größte Selbstbewusstsein? Das liegt am Dunning-Kruger-Effekt. Eine kurze Erklärung. Der Dunning-Kruger-Effekt ist ein populärwissenschaftlicher Begriff, der die maßlose Selbstüberschätzung inkompetenter Menschen beschreibt. Dunning-Kruger-Effekt: Je unfähiger desto selbstsicherer. Die Psychologen Dunning und Kruger erhielten den Ig-Nobelpreis für ihre Entdeckung, dass.

Erfahren Sie leicht verständlich, wie Sie bewusste von unbewusster Inkompetenz unterscheiden können und was der Dunning-Kruger-Effekt besagt. Dahinter steckt der Dunning-Kruger-Effekt, bei dem insbesondere inkompetente Menschen die Grenzen ihrer Kompetenz nicht erkennen.
Dunning-Kruger-Effekt. Navigation menu VideoThe Dunning-Kruger Effect John’s inability to recognize his incompetence, and the resulting overconfidence, is what is known as the Dunning-Kruger effect.

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 has kept him busy.

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.
Anchoring bias is a cognitive bias that causes us to rely too heavily on the first piece of information we What is the Framing Effect?

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. First, these deficits cause people to perform poorly in the domain in which they are incompetent.
Secondly, their erroneous and deficient knowledge makes them unable to recognize their mistakes. 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.
El efecto se debe a la incapacidad de los individuos incompetentes para reconocer su propia ineptitud, y a que los individuos muy competentes tienden a subestimar su competencia relativa.
El efecto se debe a que los sujetos afectados por este sesgo carecen con diferentes niveles de intensidad de la capacidad metacognitiva para el autoconocimiento , con lo que tiene dificultades para evaluar objetivamente su habilidad o ineptitud.

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.
No marked tendency toward overconfidence, as predicted by the effect, occurs, even in the most novice groups. In , with an updated database of over 5, participants, this still held true.
Groups' mean self-assessments prove more than an order of magnitude more accurate than do individuals'.
The discovery that groups of people are accurate in their self-assessments opens an entirely new way to study groups of people with respect to paired measures of cognitive competence and affective [ clarify ] self-assessed competence.
A third Numeracy article by these researchers  reports from a database of over participants to illuminate the effects of privilege on different ethnic and gender groups of college students.
The article confirms that minority groups are on average less privileged and score lower in the cognitive test scores and self-assessed confidence ratings on the instruments used in this research.
They verified that women on average self-assessed more accurately than men, and did so across all ethnic groups that had sufficient representation in the researchers' database.
Studies of the Dunning—Kruger effect usually have been of North Americans, but studies of Japanese people suggest that cultural forces have a role in the occurrence of the effect.
