Who Does Polygenic Selection Help?

Tight follow-up to ACX-552: addresses the objection that polygenic embryo selection doesn't 'prevent' schizophrenia but merely 'replaces a schizophrenic with a non-schizophrenic.' Via three intuition pumps (the alcoholic who does rehab then conceives a different baby; the IVF intern vs doctor picking different embryos; the sperm-jostling parenting workshop) - all cases we unproblematically call 'preventing X' yet all involve non-identity 'replacement' - Scott argues selection fairly counts as 'preventing schizophrenia,' then dispatches the anti-abortion objection (it's an argument against IVF generally, not selection).

Quality 66 · Strong. A clean, convincing philosophical clarification using the avoid-isolated-demands-for-rigor method; the three parallel non-identity cases are elegantly chosen and the argument fully resolves its question. Strong, brief: a focused (1.1k) follow-up doing one job very well.

Claude’s paradigm shift 48 · Moderate. Moderate - a clean application of non-identity reasoning to polygenic selection; a fresh framing of an existing philosophical move.

Real-world impact 2 · Minor. 2 - discourse essay on selection ethics; no material reach.
