What Do You Believe People’s “Beliefs” Are?: Dan Kahan is the Elizabeth K. Dollard Professor of Law & Professor of Psychology at Yale Law School, and a member of the Cultural Cognition Project. He is a visiting scholar at APPC for the spring 2016 semester. Abstract: “What do you believe people’s ‘beliefs’ are: (1) indicators of what they know; (2) expressions of who they are; or (3) dispositions suited for whatever it is they *do* with them?” (99) don’t know / refused. This talk will use the question of what “beliefs” measure to integrate key findings from ongoing APPC Science of Science Communication research projects. It will also venture a provisional (one would hope that goes without saying) account of how a pluralistic conception of “belief” can promote both enlargement of knowledge of how people come to know what science knows and advance evidence-based practices that enable people more reliably to recognize and give effect to scientific knowledge in their individual and collective decision-making.
