Cognitive pluralism

In this paper, we present the results of two surveys that investigate subjects' judgments about what can be known or justifiably believed about lottery outcomes on the basis of statistical evidence, testimonial evidence, and mixed evidence, while considering possible anchoring and priming effects. We discuss these results in light of seven distinct hypotheses that capture various claims made by philosophers about lay people's lottery judgments. We conclude by summarizing the main findings, pointing to future research, and comparing our findings to recent studies by Turri and Friedman.
