Why Do Transgender People Report Hypermobile Joints?

An investigation of the striking trans / Ehlers-Danlos (hypermobile-joints) correlation. Reviews four-and-a-half theories (spurious 'Instagrammable illness', estrogen, the chromosome-6 CAH/tenascin-X link, autism, and Scott's favored 4.5: poor proprioception -> a noisier, less context-dependent reasoning style that produces both autism and gender divergence), tests it on the ~7000-person ACX survey (6/6 trends in the expected direction, partially significant), and favors the proprioception model.

Quality 70 · Strong. Strong: a careful, numerate, original investigation of a genuinely odd finding using Scott's own survey data, honest about small samples; held mid-Strong by its speculativeness (the 4.5 theory is frank conjecture) and niche subject.

Claude’s paradigm shift 50 · Moderate. Moderate: the proprioception -> reasoning-style -> autism/gender causal model is a novel (if highly speculative) synthesis.

Real-world impact 1 · Negligible. Negligible/within-community: a speculative research note with no material real-world effect.
