進化生物学
Hayek had a lifelong interest in biology and was also concerned with ecology and environmental protection. After being awarded Nobel Prize he offered his name to be used for endorsements by World Wildlife Fund, National Audubon Society, and conservationist National Trust. Evolutionary biology was simply one of his interests in natural sciences. Hayek also had a unique interest in epistemology, which he often applied to his own thinking, as a social scientist. He held that methodological differences in the social sciences and in natural sciences were key to understanding why, in his mind, incompetent policies are often allowed.
