It's a blog! Mainly of book reviews.
Brief over-view of "Sex Differences in Cognition and Behaviour": too brief to say anything about the validity of the studies mentioned.
"Sex Differences in the Brain" is more detailed: Differences in the amagdala, hypothalamus and cortex. When mentioned the sample sizes are v.small (<20).
I ask: do we know enough about intra-sex variation from such small samples to be able to genuinely say anything about inter-sex variation?
