@SteveStuWill Out of my usual area, but i have a recent article on #2 (desired # partners over next 30 years). Men's means are indeed way higher then women's, but the modes of both women's and men's distributions are always 1. It complicates the picture. https://t.co/v1c39O5GUI

@Noahpinion The term "conveyer-belt media" is more appropriate.

From Orwell's essay The Prevention of Literature: "... Or perhaps some kind of low grade sensational fiction will survive, produced by a sort of conveyor-belt process that reduces human initiative to the minimum."
