“We would also expect the more masculine-looking person to have higher levels of autism traits. High functioning autism (or Asperger’s) is characterised by a very strong ability to systematize (create and work out systems) but a very weak ability to empathise. Autistics are socially unskilled, obsessed with detail, and have little interest in other people. These characteristics are associated with high testosterone. Autistics are subject to elevated fetal steroidogenic activity, including elevated levels of testosterone, as evidenced by tests of their amniotic fluid (Baron-Cohen et al., 2015). Dawson and colleagues (2007) have shown that autism is associated with a distinct intelligence profile. Autistics score strongly on the Ravens test (which strongly tests systematizing) relative to scores on broader IQ tests, which include vocabulary tests, for example. They score on average 30 percentile points higher, and in some cases 70 percentile points higher, on the Ravens than they score on the Wechsler, which is a broader test. So,”
