"Philosophic study means the habit of always seeing an alternative, of not taking the usual for granted, of making conventionalities fluid again, of imagining foreign states of mind."

Lay Epistemology


Why are there such large differences in beliefs about scientific theories like evolution and climate change? What role do beliefs about the nature of knowledge and explanation play in forming and evaluating judgments? How do people interpret disagreement, and how do they adjust their beliefs in light of new evidence or arguments?

Open-Mindedness and Pluralism


Many people value open-mindedness as a crucial facet of good thinking.  What role does this disposition really play in problem-solving and belief formation? How does it change as we grow up?

Measurement of Cognitive Dispositions


To study cognitive dispositions like open-mindedness, skepticism, and reflectiveness, we require good measures.  All measures will be flawed, but can a wider variety of quantitative and qualitative measures give us a better handle on the nature of cognitive dispositions?
