Summary

Engages Dynomight's puzzle (why do suitors prioritize attractiveness, parents wealth?). Scott rejects the older-and-wiser and Trivers-kin-selection theories (the latter refuted by the only-child case) and offers his own: the adaptation-executors-not-fitness-maximizers frame — suitors run finely-honed innate mate-choice software (attractiveness cues), while parents lack innate parental-mate-choice instincts (too evolutionarily recent) and must use human reason, which biases toward human-legible concepts like money/status. Ties it to mesa-optimizers and reptile/mammal/human-level drives.

Why this score

Quality 71 · Strong. Strong: a clever, original synthesis — the adaptation-executor lens applied to the suitor/parent split, plus the multi-level-drives musing; a genuine conceptual contribution.

Claude’s paradigm shift 52 · Moderate. Notable: a fresh application of the adaptation-executor / mesa-optimizer framework to mate choice.

Real-world impact 1 · Negligible. Within-blog evo-psych reasoning; negligible material reach. =1.
