There is really no excuse for them not trying to replicate each others studies this whole time to the point it was allowed to build into a crisis. That is a very old and well known part of the scientific method. So maybe they were somehow so ignorant of science that it was "good faith", which doesn't sound any better than doing it on purpose to me.
And psychology is hardly the only area of research, or even the worst, when it comes to this. Eg, medical research seems to be worse.
