About IQ Differences Between Men and Women
Research on IQ distributions by gender consistently finds that average general intelligence (g) scores are very similar for men and women. Most large, well-standardized test batteries show little to no reliable mean difference (around 2 points or less).
However, while the averages are similar, male IQ scores tend to show slightly larger standard deviations. Statistically, this produces greater male representation at both the lower and upper ends of the distribution, which can be visualized with the calculator above.
Differences are more noticeable in certain specific cognitive abilities. On average, females perform somewhat better on verbal fluency and processing speed tasks, while males show advantages in visuospatial tasks.
