Unskilled and unaware: Misjudgments rise with overconfidence in low performers

Overestimation and miscalibration increase with a decrease in performance. This finding has been attributed to a common factor: participants’ knowledge and s...

For instance, Miller and Geraci (2011) asked participants to predict their performance in an exam and then rate how confident they were that their self-estimates were well calibrated using a 5-point Likert scale. It was hypothesized that high levels of miscalibration would be associated with lower SOJs for students who performed well in the exam replicating Nederhand et al.’s (2020) findings. A quartile ANOVA on SOJs was conducted to evaluate whether low performers differed from more proficient peers on how confident they were that their estimated scores were well calibrated.
