Fig. 3

Effect of coursework on perceived scientific consensus on evolution. The left panel shows the distribution of the dependent variable. The right panel shows the estimates from a binary logit model predicting selection of the “81–100%” answer. The filled circles represent the estimated effect of each independent variable, and the horizontal lines show the 95% confidence interval. The vertical reference line represents the null hypothesis of no effect (an odds ratio of 1.0). An effect is significant at the 0.05 level whenever the confidence interval does not intersect the reference line. Full results are reported in Appendix Table 2
