https://en.wikipedia.org/wiki/Stereotype_threat shows up in this list as not replicated, however, it is one of the most studied phenomena in psychology.

>meta-analyses and systematic reviews have shown significant evidence for the effects of stereotype threat, though the phenomenon defies over-simplistic characterization.[22][23][24][25][26][27][28][9]

On the other hand, some empires are built on publication malpractice.

One of the worst that I know is John Gottman. Marriage counselling based on 'thin slicing'/microexpressions/'Horsemen of the Apocalypse'. His studies had been exposed as fundamentally flawed, and training based on his principles performed worse than prior offerings, before he was further popularized by Malcolm Gladwell in Blink.

This type of intellectual dishonesty underlies both of their careers.
