Conservatives
In the essay "Why I Am Not a Conservative" (1960), the economist Friedrich von Hayek said that political conservatism is ideologically unrealistic, because of the conservative person's inability to adapt to changing human realities and refusal to offer a positive political program that benefits everyone in a society.
In that context, Hayek used the term obscurantism differently, to denote and describe the denial of the empirical truth of scientific theory, because of the disagreeable moral consequences that might arise from acceptance of fact.
