Sex differences in brain size and mental abilities: comments on R. Lynn and D. Kimura

Herein, I 1. (1) show that Lynn (Personality and Individual Differences, 17, 257–271, 1994) somewhat misinterpreted my hypothesis that the relatively larger brains of men are related to their, on average, superior spatial and mathematical reasoning abilities,2. (2) argue that Lynnʹs findings strongly support this hypothesis, and3. (3) suggest that Kimura (Personality and Individual Differences, 17, 53–60, 1994) ‘missed the obvious’ while attempting to explain sex differences in spatial (and other) abilities.
