1920s

Things people believed and taught during the 1920s

Prohibition. The radio era. Eugenics at its peak in respectable journals. Cigarettes marketed to women as a slimming aid. Electric belt cures for nervous exhaustion. The 1920s carried a lot of confidence into a lot of empty corners. The decade's myths run from harmless (mood rings, ouija boards as actual spirit communication) to consequential (forced sterilisation laws based on IQ pseudoscience, lobotomies as legitimate psychiatric treatment by decade's end). The flapper got a lot of attention. The patent medicine cabinet got a lot of arsenic.
