We cannot find a single source that asserts that hypotheses, Or other specific predictions, alone constitute theory. As Kaplan (1964: 350) put it, “An explanation rests on a nomological or theoretical generalization, or an intelligible pattern, but a predication need not have such a basis. . . . We can give a reason for making some specific prediction rather than another, but we may be able to give no reason other than past successes for expecting the reason to come true.” Homans (1964), Merton (1967), and Weick (1989) are just a few of the authors who made clear that predictions Presented without underlying causal logic do not constitute theory.
