I started collecting the studies of sex differences in the summer of 2017 during the Damore-Google debacle. Over two years later I have over 70 pages of links and abstracts of such studies, both sociological and biological, ranging from moderately-strong studies to powerful meta-studies. Such knowledge is desperately needed in this day and age of rank gaslighting on the issues of sex differences, even within the church, yes, conservative churches.

Differences, of course, are not absolute and vary among individuals. But in sufficiently large group settings or in the right circumstances they can and do make a difference.

That the brain is sexed has been known for a while. This study shows the differences in gray and white matter, suggesting that brain processing is different between the sexes.

The study, Intelligence In Men And Women Is A Gray And White Matter, summarizes their findings thusly:

In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men. Gray matter represents information processing centers in the brain, and white matter represents the networking of – or connections between – these processing centers.

The study unpacks the real-world implications:

“This, according to Rex Jung, a UNM neuropsychologist and co-author of the study, may help to explain why men tend to excel in tasks requiring more local processing (like mathematics), while women tend to excel at integrating and assimilating information from distributed gray-matter regions in the brain, such as required for language facility. These two very different neurological pathways and activity centers, however, result in equivalent overall performance on broad measures of cognitive ability, such as those found on intelligence tests.”
