Are Men Smarter Than Women?
The Myth: Men are smarter than women, or women are smarter than men.
The Reality: Average IQ is identical between men and women. Men show slightly more variance (more at both extremes), but average ability is equal.
What the Science Says
Decades of research consistently show that average IQ scores are essentially identical between men and women. The difference in means is less than 1 point — statistically and practically zero. Where gender differences do appear is in the distribution: men show slightly higher variance, meaning there are somewhat more men at both the very high and very low extremes of the IQ distribution. Men tend to score slightly higher on spatial rotation tasks, while women tend to score slightly higher on verbal fluency and processing speed. These differences are small (typically 0.1-0.3 standard deviations), overlapping enormously between genders, and may be partially explained by socialization rather than biology. The claim that either gender is 'smarter' is not supported by evidence. Any observed differences in representation at the extremes reflect a combination of variance differences, socialization, and systemic factors.

Frequently Asked Questions
Are men smarter than women?
No. Average IQ is essentially identical between men and women (less than 1 point difference). Men show slightly more score variance (more at both extremes), and small differences exist in specific subtests, but overall intelligence is equal between genders.
Why are there more male geniuses?
Men show slightly higher IQ variance, meaning more men at both the highest and lowest extremes. This statistical difference, combined with historical barriers to women's education and professional participation, explains most of the observed gender gap at the highest levels. The gap is closing as barriers diminish.
Do men and women have different types of intelligence?
Small average differences exist in specific cognitive domains: men slightly favor spatial rotation, women slightly favor verbal fluency and processing speed. But these differences are tiny compared to individual variation — the smartest women outscore the vast majority of men on spatial tasks and vice versa.
