In their study , Dunning and Kruger found that training enabled participants to more accurately recognize their ability and performance.
Be open to learning new things. Curiosity and continuing to learn may be the best ways to approach a given task, topic, or concept and avoid biases like the Dunning-Kruger effect.
Everyone experiences it at some point or another. Curiosity, openness, and a lifelong commitment to learning can help you minimize the effects of Dunning-Kruger in your everyday life.

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.
Er erklärte:. The psychological phenomenon of illusory superiority was identified as a form of cognitive bias in Kruger and Dunning's study "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments".
This belief was based on his misunderstanding of the chemical properties of lemon juice as an invisible ink.
Other investigations of the phenomenon, such as "Why People Fail to Recognize Their Own Incompetence",  indicate that much incorrect self-assessment of competence derives from the person's ignorance of a given activity's standards of performance.
Dunning and Kruger's research also indicates that training in a task, such as solving a logic puzzle, increases people's ability to accurately evaluate how good they are at it.
In Self-insight: Roadblocks and Detours on the Path to Knowing Thyself ,  Dunning described the Dunning—Kruger effect as "the anosognosia of everyday life", referring to a neurological condition in which a disabled person either denies or seems unaware of his or her disability.
He stated: "If you're incompetent, you can't know you're incompetent The skills you need to produce a right answer are exactly the skills you need to recognize what a right answer is.
In , Dunning wrote about his observations that people with substantial, measurable deficits in their knowledge or expertise lack the ability to recognize those deficits and, therefore, despite potentially making error after error, tend to think they are performing competently when they are not: "In short, those who are incompetent, for lack of a better term, should have little insight into their incompetence—an assertion that has come to be known as the Dunning—Kruger effect".
Dunning and Kruger tested the hypotheses of the cognitive bias of illusory superiority on undergraduate students of introductory courses in psychology by examining the students' self-assessments of their intellectual skills in inductive , deductive , and abductive logical reasoning , English grammar, and personal sense of humor.
After learning their self-assessment scores, the students were asked to estimate their ranks in the psychology class.
The competent students underestimated their class rank, and the incompetent students overestimated theirs, but the incompetent students did not estimate their class rank as higher than the ranks estimated by the competent group.
Across four studies, the research indicated that the study participants who scored in the bottom quartile on tests of their sense of humor, knowledge of grammar, and logical reasoning, overestimated their test performance and their abilities; despite test scores that placed them in the 12th percentile, the participants estimated they ranked in the 62nd percentile.
Moreover, competent students tended to underestimate their own competence, because they erroneously presumed that tasks easy for them to perform were also easy for other people to perform.
Incompetent students improved their ability to estimate their class rank correctly after receiving minimal tutoring in the skills they previously lacked, regardless of any objective improvement gained in said skills of perception.
The study "How Chronic Self-Views Influence and Potentially Mislead Estimates of Performance"  indicated a shift in the participants' view of themselves when influenced by external cues.
The participants' knowledge of geography was tested; some tests were intended to affect the participants' self-view positively, and some were intended to affect it negatively.
The participants then were asked to rate their performances; the participants given tests with a positive intent reported better performance than did the participants given tests with a negative intent.
To test Dunning and Kruger's hypotheses "that people, at all performance levels, are equally poor at estimating their relative performance", the study "Skilled or Unskilled, but Still Unaware of It: How Perceptions of Difficulty Drive Miscalibration in Relative Comparisons"  investigated three studies that manipulated the "perceived difficulty of the tasks, and, hence, [the] participants' beliefs about their relative standing".
The investigation indicated that when the experimental subjects were presented with moderately difficult tasks, there was little variation among the best performers and the worst performers in their ability to predict their performance accurately.
With more difficult tasks, the best performers were less accurate in predicting their performance than were the worst performers.
Therefore, judges at all levels of skill are subject to similar degrees of error in the performance of tasks. In testing alternative explanations for the cognitive bias of illusory superiority, the study "Why the Unskilled are Unaware: Further Explorations of Absent Self-insight Among the Incompetent"  reached the same conclusions as previous studies of the Dunning—Kruger effect: that, in contrast to high performers, "poor performers do not learn from feedback suggesting a need to improve".
One recent study  suggests that individuals of relatively high social class are more overconfident than lower-class individuals.
When we know only a very little bit about a subject, we lack awareness of how much more there is to learn about the subject.
This means that we have no way to evaluate our level of knowledge against the total knowledge available in that subject. When we have just learned about something, we may erroneously come to the conclusion that what we have learned is all there is to learn about it.
There is another aspect to this effect which affects experts and the well-informed. While the unskilled and uninformed tend to overestimate their skills, those who are highly skilled and well-informed will tend to underestimate their knowledge and abilities.
After we have begun to explore a subject more deeply, we see how much more there is to know. At the core of the Dunning-Kruger effect is self-assessment, our capacity to judge our own abilities and skills.
This is a form of metacognition, or thinking about how we think, knowledge about how much — or how little — we know. What the Dunning-Kruger effect hinges upon is the opposite of metacognition — meta-ignorance.
This is the degree of ignorance we have regarding our own ignorance. Dunning and Kruger explained this effect with the following statement:.
The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.
