Without judging on the validity of some of the statements made/cited in the "Debunking Handbook", I can't help but wonder, how many of the psychological experimented mentioned in it are part of the reproducibility crisis.

Reading that handbook, whenever a social experiment and its outcome was mentioned, my initial thought was: "Hmm, interesting. I'd like to reproduce that experiment… several times in fact, and fiddle with the parameters, to see, if and iff so what circumstances may influence the outcome."
