Gender differences in creativity: Examining the greater male variability hypothesis in different domains and tasks

The Greater Male Variability Hypothesis (GMVH) suggests that males demonstrate greater variability than females and are overrepresented in the lowest and highest ranges of cognitive ability. Several studies have found evidence for the GMVH in creative performance, yet nearly all have used the same task (i.e., Test of Creative Thinking Drawing-Production) limiting inference to a single domain and modality of creative ability. In two studies, we examine the GMVH in relation to performance by adults (Study 1; N = 120) on a creative writing task and by adolescents (Study 2; N = 529) on a creative drawing task, as well as figural and verbal divergent thinking tasks. The variability of scores did not differ substantively between males and females on any of the tasks in either study and the pattern of the proportions of males and females in different regions of the distribution of scores was inconsistent across tasks. Although males received significantly greater mean scores than females on the verbal divergent thinking task in Study 2, no significant mean differences were found for any other task. Overall, our results do not support the GMVH and suggest that, if any, gender differences in creative variability are likely inconsistent across domains and tasks.
