I don’t understand why you need to invoke testosterone. Transgender brain is special, for example, transgender women have immunity to visual illusions. Anecdotally, I have friends with gender identity problems who do not make gender transition because it’s costly and they don’t have it this hard, they are STEM-level smart and they are not susceptible to visual illusions. So, assuming that this phenomenon exists (I don’t quite believe your twitter statistics), it’s likely explainable by transwomen innate brain structure.
The other weirdness in your hypothesis is that puberty blockers is a quite recent therapy and it’s not ubiquous—most intellectually accomplished transwomen are likely to have standard male puberty. Even low-T male have mindboggingly large amount of testosterone compared to female, which implies really weird dose-dependency between testosterone and IQ in puberty.
There are plenty of stupid and/or distracting behaviors testosterone can push you for without any kind of “chemical brain damage”, not only sex. Testosterone is likely to make you seek social status and status-seeking is notoriously incompatible with intellectual pursuits. I don’t know my testosterone levels, but I have plenty of concussions due to my tastes for physical activity and I consider myself pretty average, stereotypical male. I suspect that concussions is the first direct source of male brain deterioration and testosterone is related here because it induces risk-seeking. The second and third, I think, smoking and drinking, and non-surpisingly, it’s another sort of typical risky teenage male activity.
transgender women have immunity to visual illusions
Can you source this claim? I’ve never heard it and GPT-4 says it has no scientific basis. Are you just referring to the mask and dancer thing that Scott covered?
Whoops, it’s really looks like I imagined this claim to be backed more than by one SSC post. In my defense I say that this poll covered really existing thing like abnormal illusions processing in schizophrenics (see “Systematic review of visual illusions schizophrenia” Costa et al., 2023) and I think it’s overall plausible.
My general objections stays the same: there is a bazillion sources on brain differences in transgender individuals, transgenderism is likely to be a brain anomaly, we don’t need to invoke “testosterone damage” hypothesis.

This is the strongest alternative explanation by far. I wonder what to look for to check this...
