Hayek opposed not merely Keynes’s policy recommendations, but his technical method. - Alan O. Ebenstein

True and false individualism differ, according to Hayek, not primarily about values but about facts. The question of how societies are actually ordered or organized separates them: Are communities created, or do they evolve? The answer is obviously some combination of the two, but the relative weighting is of the greatest importance.

Hayek was in many respects a philosophical idealist, in that he believed that ideas rule the world. It was the idea of constructivism, he thought, that has such destructive consequences. If he could combat this idea, then much good would result.

At the same time, as Hayek maintained elsewhere, the facts of the social sciences do not lend themselves to the same degree of prediction, or explanation, as the facts of the natural sciences—it is for this reason that there are degrees of prediction or explanation. Prediction may be expressed numerically, moreover, “not as a unique value or magnitude but as a range,” narrow in the natural sciences and potentially very broad in the social sciences. In the social sciences, Hayek modified the conception of a numerical range to a “range of phenomena to expect.” This was his concept of pattern prediction, or explanation of the principle, broad, general predictions.
