The sample was 63% White, 13% Black, 11% Latin American, 6% Multi-Racial, 4% East Asian, and 3% other ethnicities. Of these, 504 participants (90.5%) provided a final hypothesis and were included in discovery rate analyses, while 512 participants (91.9%) provided a final likelihood rating and were included in confidence change analyses.
