Or maybe, human psychology is too complicated with too many factors influencing results to be easily reproducible. The crisis is then more in the expectation you have and about initial small scale experiments being treated as "truth" and expected to work across cultures, social groups and social situations. Apple always falls down, but how people respond is sensitive to a lot of context.

Some of crisis are frauds or shaddy science (prison experiment). Some of it is the simplistic expectation that since experiments in basic physics are simple, psychology and sociology should be equally simple.

Lastly, these science are call soft, because they use less math and deal with fuzzy issues.
