- * *Claim*: Trans people are born with a brain-restricted intersex condition such that their psychology is much more typical of the other physiological sex: the proverbial "woman trapped in a man's body" (respectively "man ... woman's") trope is basically accurate.
- * *Claim*: The medical interventions undergone during transition—hormone replacement surgery, sex reassignment surgery, _&c._—are effective at inducing the phenotype of the other physiological sex: physically, transitioning _works_.
- * *Claim*: Gender is mostly attributed on the basis of apparent secondary sex characteristics: in most situations, most people don't care about predicting the configuration of someone's genitalia at birth or whether they have a Y chromosome.
- * *Conclusion*: Trans people can legitimately be said to belong to their stated gender, using the _same_ criteria people usually use to decide such things.
+The pre-verbal, subconscious, [System 1](https://en.wikipedia.org/w/index.php?title=Dual_process_theory&oldid=820860981#Systems) process by which we notice someone's features (breasts, facial hair, voice, facial structure, gendered clothing or grooming cues, any number of [subtle differences in motor behaviors](https://sillyolme.wordpress.com/2010/09/24/all-the-wrong-moves/) that your perceptual system can pick up on without you being consciously aware of them, _&c._), mentally categorize them as a _woman_ or a _man_, and use that category to guide our interactions with them, isn't subject to conscious control—but, for most purposes in day-to-day public life, it's also not _directly_ focused on genitalia or chromosomes.
