One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision - Bertrand Russell As Bertrand Russell noted, those most confident in their level of expertise and skill are not necessarily those who should be.

These biased self-evaluations are not only seen in the laboratory, but also arise in important real world settings. Academics are not immune. Absent Self-Insight Among the Incompetent Why are people typically so convinced that they are more capable than they, in fact, are?

In recent years, an active and emerging literature has grown to explain errors in self-assessment. One strategy for understanding the sources of error in self-assessment is to identify those individuals who make the most mistaken self-judgments.

By examining how these error-prone individuals differ from their more accurate peers, one can identify sources of error in general. Adopting this approach, Kruger and Dunning suggested that, across many intellectual and social domains, it is the poorest performers who hold the least accurate assessments of their skill and performances, grossly overestimating how well their performances stack up against those of their peers.

Kruger and Dunning argued that this gross overconfidence occurs because those who lack skill simply are not in a position to accurately recognize the magnitude of their deficits.

Their incompetence produces a double curse. First, their lack of skill, by definition, makes it difficult to produce correct responses and, thus, they make many mistakes. Second, this very same lack of skill also deprives them of success at the metacognitive task of recognizing when a particular decision is a correct or an incorrect one. For example, to produce a grammatically correct sentence, one must know something about the rules of grammar.

Thus, those who lack grammatical expertise are not in a position to accurately judge the quality of their attempts or the attempts of other people. Consistent with this argument, poor performers are significantly worse at distinguishing between correct and incorrect responses than are their more competent peers for a review, see Dunning, This is true when judging their own responses e.

To be sure, the incompetent are not alone in their difficulty with accurate self-assessment. These same studies suggest that top performers consistently underestimate how superior or distinctive their performances are relative to their peers. Kruger and Dunning suggested that this underestimation stems from a different source — because top performers find the tests they confront to be easy, they mistakenly assume that their peers find the tests to be equally easy.

As such, their own performances seem unexceptional. Supporting this proposal, Kruger and Dunning found that exposing top performers to how their peers performed on the same task caused them to recognize, in part, just how exceptional their performances were relative to their peers see Hodges et al. Goals of the Present Research The primary aim of this manuscript is to advance an understanding of why the incompetent, in particular, tend to lack self-insight.

Although a growing body of evidence has provided support for the claim that incompetence hinders self-insight e. These critiques argue that the self-assessment errors observed by Kruger and Dunning can be largely reduced to statistical or methodological artifacts rather than to an absence of metacognitive competence among poor performers.

Metacognitive Error or Statistical Artifact? Two alternative accounts have been published to explain the pattern of over- and underestimation of performance observed by Kruger and Dunning Central to these critiques is the notion that top and bottom performers actually do not differ in their ability to evaluate the quality of their own performances.

Instead, it is argued, people of all skill levels have equal difficulty estimating the quality of their performance — and it is this shared difficulty, coupled with statistical or methodological artifacts, that account for the observed patterns of over- and underestimation. Instead, they argued, the pattern was produced by regression to the mean coupled with the fact that people tend overall to rate themselves as above average Alicke, ; Brown ; Krueger, Because perceptions of performance correlate imperfectly with actual performance, it was nearly inevitable that the self-assessments of bottom performers would regress back to toward an average self-assessment, thus ensuring that their estimates would be higher than the performance they achieved.

Similarly, the performance estimates made by top performers would regress back toward the average, ensuring that their true performance would be higher than their corresponding estimates. According to Krueger and Mueller this regression to the mean phenomenon arises, in part, because measures used to assess the skill level of participants are statistically unreliable and, thus, fraught with measurement error.

This unreliability would ensure a smaller correlation between perceptions and the reality of performance, leading to more regression to the mean and greater levels of over- and underestimation. If one measured and then corrected for that lack of reliability, they argued, a good deal of over- and underestimation would evaporate. Their argument, drawing upon Kruger , noted that above average effect frequently occurs for tasks that people perceive to be easy but that tasks perceived to be difficult can produce below average effects.

When faced with great difficulty in completing a task, individuals believe that they are performing poorly and, failing to properly account for the degree to which others also experience this difficulty, assess their relative performance as worse than average. Burson and colleagues argued that, if everyone produces similar estimates estimates that are high for tasks perceived to be easy but low for tasks perceived to be difficult what dictates accuracy is less a matter of greater insight on the part of some participants and more a matter of perceived difficulty.

When a test seems easy, everyone will believe they have performed well relative to their peers but only top performers will be accurate, leaving bottom performers overconfident. When the test is construed to be hard, however, everyone will think they have done poorly relative to the peers and bottom performers will be more accurate than their more competent peers.

In short, whether top or bottom performers are most inaccurate is an artifact of the perceived difficulty of the task. Indeed, Burson and colleagues presented participants with tasks perceived to be difficult in three studies and found support for their assertions.

Participants estimated how well they had performed on tasks e. Across these studies, Burson and colleagues found that estimates of performance did not correlate well with actual performance but correlated highly with difficulty condition. After completing an easy task, participants of all skill levels estimated that they had performed well relative to their peers, such that top performers looked relatively accurate and bottom performers were grossly overconfident.

However, after completing a difficult task, participants of all skill levels estimated that they had performed quite poorly relative to their peers, making poor performers look quite accurate and top performers vastly underconfident. Although Burson and colleagues largely focused this critique on comparative and not absolute estimates of performance, they took their results as evidence that the Kruger and Dunning pattern of over- and underestimation of relative performance was simply a function of using seemingly easy tasks and, as such, did not provide evidence of a relationship between skill level and accuracy in self-assessments.

The Present Investigations The following studies were designed to address the above critiques and, more generally, provide a better understanding of the relationship between level of skill and accuracy in self-assessment.

We have organized the studies described in this manuscript in three sections, each with a separate aim. Section 1 Section 1 was designed to directly address the claims that apparent over and underestimation among bottom and top performers can be reduced to statistical and methodological artifacts.

We did this in several ways. To address the claims made by Krueger and Mueller , we explored the accuracy of self-assessments after correcting for lack of statistical reliability in our datasets. Second, given the Burson et al. Burson et al. As such, they showed what could happen at the extremes of human performance. In addition, they also chose tasks that participants were likely not to have much experience or familiarity with, such as trivia questions or a word game, which meant that participants faced a notable degree of uncertainty about how they or their peers would perform.

Those choices left open the question of what patterns of assessments people would make if they dealt with a type of task they were very likely to face in real life—with which they had some familiarity about how they and their peers would performed.

A quick look at overall performance levels attained by participants in Kruger and Dunning suggests that the patterns of over and under-confidence would look quite different from what Burson et al.

According to Burson et al. The tasks used in Kruger and Dunning, however, look anything but easy. The average performance participants attained ranged from Bottom performers answered between Yet, even facing these difficult tasks, poor performing participants still grossly overestimated their performance relative to their peers. Thus, in Part 1, we looked at real world cases in which people approached often challenging tasks that they would encounter anyway in their everyday lives, rather than ones managed by experimenters to seem either easy or difficult.

In these ecologically valid circumstances, would we tend to find the pattern of self-assessments observed by Kruger and Dunning or would the pattern look different? We took this direction because we thought it would be critical to explore error in self-assessment on ecologically representative and familiar tasks in real-world settings. In particular, we asked undergraduate students to estimate how well they had performed on course exams and asked members of college debate teams to evaluate their tournament performance.

These tasks were chosen because they were ones that individuals approached out of their own volition as opposed to having the task imposed by an experimenter , they were devised by naturally-occurring agents e. In addition, Burson et al inspired us to explore a wider range of self-assessment measures. Their argument about task difficulty rested largely on the use of comparative measures in which people evaluated their performance relative to their peers.

They argued that people would underestimate themselves on difficult tasks and overestimate themselves on easy tasks because of the inherent difficulty of knowing how their peers had done, regardless of the skill level exhibited by the person making the evaluation. But what about estimates that do not involve comparisons with peers? We predicted that poor performers would overestimate their performance on absolute as well as relative measures, with top performers being largely accurate in their assessments.

Section 2 In Section 2, we examined a third plausible alternative explanation of the pattern of over- and underestimation observed by Kruger and Dunning One could argue that a goal to preserve a positive, if not accurate, view of the self may be particularly strong among those who have performed poorly precisely because these are the individuals who might suffer the most from admitting the reality of their poor performance. Those who score very well, in contrast, would have considerably less motivation to glorify the quality of their performance.

Indeed, they may be motivated instead to be overly modest about their achievement. Under this analysis, those who are unskilled can and will recognize how poorly they have performed if properly motivated.

Thus, in the three studies comprising the second section, we offered incentives to encourage participants to provide accurate self-assessments. If the unskilled are truly unable to evaluate the quality of their performances, their performance estimates should remain inflated even in the face of strong incentives to be accurate.

Section 3 The first two sections of this paper speak primarily to factors that do not influence performance estimates, while simply referring back to previous literature to clarify what does influence estimates.

This focus stems directly from the alternative explanations provided in critiques of Kruger and Dunning In Section 3, however, we provide a meta-analysis of existing data to look directly at the specific errors leading to overestimation of comparative performance among poor performers and underestimation by top performers. According to Kruger and Dunning , poor performers overestimate their abilities because they do not have the metacognitive skill to know that they themselves are doing poorly.

The major problem is one of self-estimation, not estimation of peers. Top performers, on the other hand, may underestimate how well they are doing relative to their peers because they overestimate how well their peers are doing. That is, mistaken assessments of peers become a more substantive portion of why top performers fail to recognize the rarity of their competence.

Our analysis in Section 3 directly explored the influence of these differing sources of error on self-assessments made by top and bottom performers.

In doing so, it served as a response to both the Krueger and Mueller and Burson et al. If we could tie patterns of over- and underestimation more closely to the types of specific errors predicted by Kruger and Dunning , we would then provide evidence in support of or against their account.

Section 1: Correcting for Reliability in Self-Assessments for Real World Tasks All too often, social psychological research remains in the laboratory and we are left to infer that the same phenomenon routinely occur in the real world. For this reason, the discipline is often open to the criticism that what we find is limited to particular contrived laboratory situations or to particular demographics e.

Real world demonstrations are particularly important in this case because critiques of Kruger and Dunning have centered on whether their findings are limited to particular types of tasks e.

Thus, in this section, we examined the accuracy of self-assessment among top and bottom performers on real world tasks.

Why the Unskilled Are Unaware: Further Explorations of (Absent) Self-Insight Among the Incompetent

This belief was based on his misunderstanding of the chemical properties of lemon juice as an invisible ink. The skills you need to produce a right answer are exactly the skills you need to recognize what a right answer is. 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. 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.
