there is a theory or, more properly, a hypothesis behind the "if it work, it works" approach. Namely, the implicit assumption, or hypothesis is that it works. Your empirical evidence does not contradict the (implicit) hypothesis and so, you accept your hypothesis as a working theory.
I started with the same hypothesis but, my empirical evidence contradicted the "it works" hypothesis so, I am forced to reject the hypothesis.
