As far as I know I’m the only one arguing that the autistic spectrum should be described as the “solipsistic-autistic spectrum”, but I might argue that I’m just using loaded language to demonstrate and allow us to criticize the failure of the female side of the spectrum as well as the male. That is because women are are as comfortable using solipsistic arguments as we are using autistic. However, I’m pretty sure that the basic thesis is correct. That is, that most of these brain states are produce by in-utero chemistry.
