The Chateau’s response to the brain study is about as calm and understated as one would expect….

As is so often the case, though, there is something hard and logical beneath the savage provocation. I very strongly suspect, as, I think, Heartiste does as well, that the wiring of Gamma brains will show up differently on brain scans than other male brains.

Here is my scientific hypothesis: The reason Gamma male thought processes and conclusions tend have more in common with female thought processes and conclusions than with normal male thought processes and conclusions is because they have more of the inter-hemisphere connections and less of the intra-hemisphere connections than normal men.
