Limited Informativeness of Rejecting the Null Hypothesis
Critics argue that rejecting a null hypothesis is often uninformative because it only asserts that a relationship is 'nonzero' without describing its actual magnitude. Furthermore, since relationships in the population are rarely exactly zero, rejecting a null hypothesis may simply confirm a fact that was already likely to be true without providing new insight.
