Big-brained people are smarter: A meta-analysis of the relationship between in vivo brain volume and intelligence
Michael A. McDaniel
Abstract
The relationship between brain volume and intelligence has been a topic of a scientific debate since at least the 1830s. To address the debate, a meta-analysis of the relationship between in vivo brain volume and intelligence was conducted. Based on 37 samples across 1530 people, the population correlation was estimated at 0.33. The correlation is higher for females than males. It is also higher for adults than children. For all age and sex groups, it is clear that brain volume is positively correlated with intelligence.

oh that is interesting, the correlation is stronger for woman. the reason i find it interesting is i observe a correlation between smaller skulled woman and patriarchal cultures. it would be only natural that this all to common phenomenon would induce a stronger capacity and relation per cc for woman.
(since no matter that small headed woman may appear girlish and 'nice and stupid' (ie easily dominated) there would be strong limitation in survivability for the children if a smaller head translated in a much more stupid woman that easily.) very nice to see evolution counter machismo.
