Why Are Transgender People Immune To Optical Illusions?

A flagged-as-'so, so speculative' synthesis chaining a striking set of connections around the NMDA glutamate receptor. From his own 5,000-response blog survey, Scott reports that schizophrenics, autistics, and -- most strikingly -- transgender readers show altered responses to the Hollow Mask and Spinning Dancer illusions (less 'glitching'). He then builds a predictive-coding story: NMDA receptors carry top-down priors (Corlett's model), so NMDA hypofunction means the prior loses and you see through the illusion; schizophrenia and autism both involve NMDA hypofunction; dissociation (high in trans people, per Zinnia Jones's prompt) is reliably NMDA-antagonist-induced (ketamine, DXM); estrogen enhances NMDA function and treats dissociation/schizophrenia/autism-in-models -- so perhaps NMDA hypofunction underlies trans identity, tying the whole web together. Crucially, the post is a model of epistemic hygiene: a closing six-point skeptical section flags that NMDA research 'explains everything' (red flag), the multiple-comparisons problem, the non-correlating Spinning Dancer, the failed ketamine prediction, the trans-men-use-testosterone problem, and the 'trans people have elevated rates of every illness' confound. Idea-dense, intellectually courageous on a fraught topic, and a clear precursor to his later predictive-coding/trapped-priors psychiatry. REPLICATION CAVEAT: the empirical core is an underpowered, multiple-comparisons-laden blog survey that (to my knowledge) was never independently replicated, and the central thesis is explicitly tentative -- so quality-as-it-reads-now is docked and confidence set to Med, though the synthesis and self-skepticism remain genuinely valuable.

Quality 70 · Strong. Strong (70): high originality, idea-density, and exemplary self-skepticism, with a predictive-coding framing that prefigures his influential later work -- but docked out of the Excellent band because the empirical foundation (the survey illusion-correlations) is shaky/unreplicated and the thesis is, by Scott's own framing, very speculative. Credit for the synthesis and hygiene; debit for the fragile data.

Claude’s paradigm shift 52 · Moderate. Moderate-to-Notable (52): the NMDA / predictive-coding / gender / perception synthesis was a genuinely novel and non-obvious weave in 2017 and seeded a frame Scott developed further; short of higher because it assembles existing pieces (Corlett's model, NMDA-hypofunction theories, estrogen findings) rather than establishing a validated new paradigm.

Real-world impact 2 · Minor. A highly speculative, unreplicated predictive-coding/NMDA synthesis from a blog survey; intriguing within the discourse and a precursor to his later work, but no concrete clinical or material-world impact of its own → RWI 2.
