It is true that psychology as it is currently practiced in many places has one of the worst replication crises [1] of all sciences, with lots of p-hacking and other unethical practices going on as researches attempt to get publishable results in a field where most data you get is necessarily messy and difficult-to-control confounding variables abound. But that's more about the usual perverse incentives in the academia rather than a fundamental problem with the field itself.
