Three pre-registered experiments. One story. But now with page numbers. Non-heterosexual behaviour/identities among men is punished significantly more than the same among women.

#OTD 1857 John Snow shows again the thinking that made him one of the founders of epidemiology. In a letter to the Lancet, he suggests that the routine adulteration of bread with alum might be a cause of rickets, a mechanistic hypothesis to explain it, then a case-control design to test it. 1/5🧵

Faculty are forever making fun of students for asking questions that are answered on the syllabus but if you’ve ever been to a faculty meeting you know that faculty constantly ask questions that are answered by the program handbook or departmental bylaws. Constantly (me included).

As I have been arguing for almost a decade, populism is a secondary feature for most populist actors. Moreover, the main current threat to liberal democracy comes from the far right, which at least in Europe and U.S., is primarily nativist. In fact, some are barely populist anymore.
