Two related studies investigated sex differences in self‐ and parental estimates of IQ scores on specific scales derived from standardized and validated IQ tests. In the first study 210 participants were asked to estimate their scores on the 11 WAIS‐R subtests as well as their overall general IQ. Results showed males estimated their overall score, plus their total WAIS score, significantly higher than females, with effect sizes around 0.5. Factor analysis showed participants did differentiate between verbal and performance subscale scores on this test. In the second study 117 participants performed a similar task, but this time on the 12 subscales of the Stanford‐Binet test. Males estimated their overall score higher than females. Factor analysis also showed 2 clear factors that reflected exactly the verbal and performance subscale scores.
