Of course psychology is less exact than physics or mathematics, and that is not at all a bad thing, it doesn't make it inferior. The problem, I think, occurs when people try to treat psychology or sociology etc. as more of an exact science, for instance by treating statistical correlations as causal ones. Feynman has an interesting essay about that, I think
