Why are transgender people immune to optical illusions? (2017)

Autistic readers were only slightly more likely to report a weak reaction to the mask illusion than neurotypicals (17% vs. 14%), but thanks to our big sample size we could be pretty confident that this was a meaningful difference (p = 0.004). But one stood out: transgender people had an altered response pattern on both illusions, stronger than the alteration for autism and almost as strong as the one for schizophrenia (mask: cis 14% vs. trans 21%, p = 0.003; dancer: cis 58% vs. trans 71%, p = 0.001). They cite one study showing 8% autism rate in trans people (compared to 1-2% in the general population), and another showing that autistic people were 7.5x more likely to express “gender variance”.
