Unskilled and unaware of it: How difficulties in recognizing one's own incompetence lead to inflated self-assessments

Kruger, Justin, Dunning, David·1999·Journal of Personality and Social Psychology

Abstract

People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that 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. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd. Several analyses linked this miscalibration to deficits in metacognitive skill, or the capacity to distinguish accuracy from error. Paradoxically, improving the skills of participants, and thus increasing their metacognitive competence, helped them recognize the limitations of their abilities.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Kruger and Dunning (76) demonstrated that individuals with limited competence in a given domain tend to lack awareness of that very limitation, resulting in systematic self-assessment inflation.

    “This pattern is consistent with the metacognitive model formulated by Kruger and Dunning (76), who demonstrated that individuals with limited competence in a given domain tend to lack awareness of that very limitation, resulting in systematic self-assessment inflation.”
  • The finding that middle performers show the largest metacognitive disconnect is inconsistent with previous studies that identified low-performing students as demonstrating the most significant metacognitive disconnect due to the Dunning-Kruger effect.

    “which is inconsistent with previous studies that have identified low- performing students as demonstrating the most significant metacognitive disconnect due to the Dunning- Kruger effect (Kruger & Dunning,1999; Ehrlinger et al.,2008; Sawdon & Finn,2014; Steuber et al.,2017).”

  • The decline in performance of human-AI teams when tackling tasks of medium complexity suggests that users may have faced challenges in accurately assessing their own abilities and the capabilities of AI systems, primarily by overestimating their own abilities.

    “The decline in performance of human-AI teams when tackling tasks of medium complexity suggests that users may have faced challenges in accurately assessing their own abilities and the capabilities of AI systems, primarily by overestimating their own abilities [64].”
  • Psychological evidence suggests that individuals who do not know much about a subject tend not to recognize their ignorance and therefore typically fail to seek better information.

    “By contrast, this literature suggests that individuals who do not know much about a subject tend not to recognize their ignorance and therefore typically fail to seek better information (Kruger and Dunning 1999).”

  • Media literacy has long focused on personal responsibility, which can imbue individuals with a false sense of confidence in their skills and put the onus of monitoring media effects on the audience rather than media creators, social media platforms, or regulators.

    “Media literacy has long focused on personal responsibility, which can not only imbue individuals with a false sense of confidence in their skills (Sanchez & Dunning, 2018; Kruger & Dunning, 1999), but put the onus of monitoring media effects on the audience, rather than media creators, social media platforms, or regulators.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
