Dunning-Kruger Effect: New study says ignorance and overconfidence affect intuitive thinking

In a newly published study, researchers say the Dunning-Kruger Effect can cause low-performers to overestimate their judgments during the intuitive decision-making process. According to the study published in the journal Frontiers in Psychology on April 8, 2021, researchers found that persons with the highest number of errors demonstrated the highest degree of miscalibration, or overconfidence, in their actual performance on the cognitive reflection test. Researchers say study results have potential implications for the theoretical cognitive bias that persons with low abilities tend to overestimate their actual capabilities, also known as the Dunning-Kruger effect. Speaking with The Debrief, Dr. Justin Couchman, professor of psychology at Albright College and co-author of the recent study, says the ability to make correct intuitive decisions is increasingly becoming one of the most critical skills to have in the modern information-technology age.
