Question

Quizplus · Accepted Answer

Contemporary neuroscientific research suggests that there may be some differences in brain structure between groups of individuals, such as between women and men. However, these differences are generally smaller than popular theories suggest. Studies have shown that there is much more variability in brain structure within groups than between groups, and that the differences between individuals within a group are often larger than the differences between groups.
