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.

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.
