Sex Differences in Cognitive Reflection: A Meta-Analysis

Abstract

The current study presents a meta-analytic review of the differences between men and women in cognitive reflection (CR). The study also explores whether the type of CR test (i.e., numerical tests and verbal tests) moderates the relationship between CR and sex. The results showed that men score higher than women on CR, although the magnitude of these differences was small. We also found out that the type of CR test moderates the sex differences in CR, especially in the numerical tests. In addition, the results showed that the length of numerical tests (i.e., number of items) does not affect the differences between men and women in CR. Finally, the implications of these results are discussed, and future research is suggested.
