Thanks! That's interesting, seems I might have had it wrong. I should've brought that up during my friends master thesis presentation, maybe he wouldn't have got his diploma ;) Are psychology researchers in general aware of this review? Obviously my friends master thesis was just a small inconsequential study, but if the universals that are now commonly used have turned out to not actually be true wouldn't that mean huge swathes of researchers have to retract/redo their research?

Reproducibility is a major concern. Many experiments are poorly designed.

So, yes, about 60% of research needs to be redone.
