↳ Suddenly, Trait-Based Embryo Selection — Essay · Jul 2025
Summary
Scott answers three objections to embryo selection. (1) Are embryos persons/moral patients? He dismantles the potential-person argument: sperm, pizza (eaten by a pregnant woman), and an iron block before a sentient-robot factory all have 'potential' too; every patch (has-all-the-info, is-self-assembling) either rules in sperm-egg pairs and timer-set robot-computers or collapses into gerrymandering (the deliberately absurd 'must start with the letter E' criterion). His positive view: personhood is about consciousness/preferences/hopes, which embryos lack -- and personhood for edge cases (the sleeping hermit; a patient mid-cellular-disassembly-surgery in the transhuman future) is a 'residual claim'/useful legal fiction, with the newborn handled by fence-around-the-law bright lines. (2) Diversity loss? Weak (any optimizing tech homogenizes-and-diversifies) plus strong (selection is weak [70-30], slow [~40 yrs to matter], and even smartest-1%-skewed adoption only shifts genius counts), with the asymmetry that benefits accrue to specific people while harms require affecting the whole race. (3) 'Would you tell a disabled person you'd rather they not exist?' -- the rape/lobotomy/war parallels: you can want less of X in future without deeming existing X-people inferior.
Why this score
Quality 74 · Strong. Strong, upper band. Sharp applied-ethics: the sperm/pizza/iron and 'starts with E' reductios and the cellular-disassembly thought experiment are genuinely good, and the personhood-as-residual-legal-fiction framing is clean. Held just below Excellent as a (characteristically strong) rebuttal-and-defense rather than a standalone landmark.
Claude’s paradigm shift 52 · Moderate. Moderate. The consciousness-based personhood view and the potential-person counterexamples are familiar Scott/utilitarian material; the fresh contributions are the residual-claim framing and the disassembly-surgery thought experiment.
Real-world impact 2 · Minor. Minor. Advocacy within the embryo-selection/transhumanist discourse for a real but slowly-deploying biotech; the post's own reach is discourse-level. 2.
