Gender and task confidence as predictors of the Domain-Masculine Intelligence Type (DMIQ)

•Males rated their mathematical and spatial intelligence higher than females before and after an IQ test.•Males estimated their probably success higher than females.•There was no sex difference on the ability test.•Gender and actual task success scores were predictors of self-estimates, with the former being twice as powerful as the latter.

This study investigated the relationship between gender, ability tests and task confidence as predictors of self-estimated intelligence. Participants estimated their mathematical and spatial intelligence before and after completing various ability tests which they also rated for their probable success. Males rated their intelligence higher than females on both before and after measures, as well on their task estimated probably success. There was no sex difference on the ability test. Gender and actual task success scores were predictors of self-estimates, with the former being twice as powerful as the latter. The results are discussed in terms of gender differences in confidence and expectations when approaching ability tests and their effect on self-estimated intelligence.
