“Amusing Ourselves to Death? § Loehlin & Nichols 1976_48ya: A Study of 850 Sets of Twins”, Gwern2018-05-12 (sociology of tech, transhumanism)⁠:

A suggested x-risk/Great Filter is the possibility of advanced entertainment technology leading to wireheading/mass sterility/population collapse and extinction. As media consumption patterns are highly heritable, any such effect would trigger rapid human adaptation, implying extinction is almost impossible unless immediate collapse or exponentially accelerating addictiveness.

A discussion of extracting ~376 behavioral items relating to recreation/leisure from Loehlin & Nichols 1976_48ya: A Study of 850 Sets of Twins, which reports comprehensive summary statistic twin correlations from an early large-scale twin study (canvassed via the National Merit Scholarship Qualifying Test, 1962_62ya). I transcribe them from the book, pool the weighted correlations by gender, and compute simple heritability estimates by Falconer’s formula for use in the recreation/leisure heritability literature review.
