Dunning-Kruger Effect: Intuitive Errors Predict Overconfidence on the Cognitive Reflection Test

The Cognitive Reflection Test (CRT) is a measure of analytical reasoning that cues an intuitive but incorrect response must be rejected for successful performance to attained. CRT yields two types errors: Intuitive errors, which are attributed Type 1 processes; and non-intuitive result from poor numeracy skills or deficient reasoning. Past research shows participants who commit the highest numbers errors on overestimate their most, whereas those with lowest error-rates tend slightly underestimate. This example Dunning-Kruger Effect (DKE). present study examined how vs. contribute overestimation in at different levels performance. Female undergraduate students completed seven-item test subsequently estimated raw score. They also filled out Faith Intuition (FI) questionnaire, dispositional thinking. Data was separated into quartiles based level CRT. results demonstrated DKE. Additionally, predicted miscalibration among low, not high performers. However, were stronger predictor miscalibration. Finally, FI positively correlated self-estimates miscalibration, indicating perceived themselves more worse estimating These taken together suggest perform poorly score higher thinking disposition susceptible influences heuristic-based cues, such as answer fluency, when judging
