Truth and Post-Truth in Public Policy

This Element shows that the effort to understand the phenomenon of post truth has to go beyond the emphasis on facts to include an understanding of the social meanings that get attached to facts in the political world of public policy.

The phenomenon of post-truth poses a problem for the public policy-oriented sciences, including policy analysis. Along with “fake news,” the post-truth denial of facts constitutes a major concern for numerous policy fields. Whereas a standard response is to call for more and better factual information, this Element shows that the effort to understand this phenomenon has to go beyond the emphasis on facts to include an understanding of the social meanings that get attached to facts in the political world of public policy. The challenge is thus seen to be as much about a politics of meaning as it is about epistemology. The analysis here supplements the examination of facts with an interpretive policy-analytic approach to gain a fuller understanding of post-truth. The importance of the interpretive perspective is illustrated by examining the policy arguments that have shaped policy controversies related to climate change and coronavirus denial.
