Secrets Of The Great Families

Asks how dynasties (Huxleys, Darwins, Bohrs, Poincares, Curies, Dysons, Tagores) keep producing talent across generations. Dismisses pure privilege (most weren't fantastically rich; hard-to-fake achievements), then takes genetics seriously while owning its puzzles: regression to the mean should dilute talent fast, and siblings express it in wildly different fields (a physicist and an Olympic footballer). Answers with the IQ-regression math showing that ferocious assortative mating (marrying Norlund's sister, Keynes's brother) plus huge broods keeps the loss to a few points a generation; 'Generic Talent Genes' that are g-loaded across music, politics, and even elite sport; inconclusive but uniformly weird educations; and Yudkowsky's 'Hero License' -- you aim at greatness if your family makes it the default (doctors' kids are 25x more likely to be doctors).

Quality 72 · Strong. Strong. Entertaining and genuinely numerate -- the regression math and the assortative-mating + brood-size answer do real work, and Hero License is a memorable closer. Held mid-Strong because it's a lighter, anecdote-rich survey rather than a tight argument.

Claude’s paradigm shift 52 · Moderate. Moderate. Draws on established behavioural genetics; the fresh part is the synthesis (assortative mating + litters + Generic Talent Genes + Hero License) into a single account of dynastic talent.

Real-world impact 2 · Minor. Minor. Behavioural-genetics / rationalist discourse; no material reach. Within-niche.
