The standard phrase you learn early in statistics is "correlation is not the same as causation." That is, if A and B are correlated, you don't know whether it's A causing B, or B causing A, or some unknown C is causing them both. There are fancier statistical tests than correlation that purport to tell whether A->B or B->A.
On psychosocial stuff, some people think that if you find some neurochemical phenom associated with behavior or affect, you've identified the underlying cause. But it could be that experience affects the neurochemistry, and it's really an effect.
