3 studies: poor control sample, small sample, no ID of social factors, no analysis of indirect effects of T (mood swings, increased sex drive) that could drive behavior changes that translate to changes in brain.

But given that the same sex differences in verbal and mental rotation skills are found in many replicated studies outside the trans field, this seems like corroboration that hormones directly impact the brain. Why wouldn't they? They do in every other animal.

Not saying hormones don't affect the brain. They affect emotional stability, particularly when artificially manipulated. That may have an indirect affect on verbal processes.

Why is in the only possibility that the effect is "indirect"? What if the effect is also direct? Why is that not possible?

There are very good reasons why there would be selective evolutionary pressure on females to have superior communication skills.

There is evidence that we select for superior communication based on female socialization. Enough to explain the difference. There may be a small innate difference between boys and girls, but I don't see why it matters, when socialization is such a huge factor.

Except that socialization and culture (of course they matter!) didn't appear in a vacuum--or on a blank slate, if you prefer. We are primates, and like our cousins, evolution exerted selective pressure on us, as on all animals, from the beginning.

Social behavior is a part of evolution, especially for gregarious species such as ours. I don't understand why the need to identify a possible .001% innate difference in boy/girl brains is so important, unless it's to justify "man in his sphere, woman in hers" thinking.

Scientific inquiry is pursuit of understanding. Misusers w/an agenda gonna misuse. Example: If women **ON AVERAGE** prefer "people jobs" such work should be valued & better paid, not denigrated as less than "thing" jobs--while STILL encouraging girls who want to to be engineers.

Scientific inquiry is usually political and agenda driven. Asking what the purpose is of assigning continued resources in this area is valid. What is the agenda?

I'm not prepared to agree any scientist who studies something that could be used for a nefarious purpose is driven by a hidden agenda. There are many scientists with integrity. Not everyone is an ideologue. In fact, those trying to shut down inquiry seem more agenda-driven to me.
