Erratum: No Missing Link: Knowledge Predicts Acceptance of Evolution in the United States (BioScience DOI: 10.1093/biosci/bix161)

In the pre-registration for this paper (https://osf.io/mvg4n), we said that we would count the total number of participants who failed our evolution knowledge battery and the Ordinary Science Intelligence scale and use non-parametric tests to determine whether this is significantly more than a quarter of the sample. The pre-registration defined failing as scoring less than 70%. A reviewer pointed out that a more accurate criterion of failing would count participants who scored less than 60%, so we used this threshold in the paper. Here we report analyses in line with our original pre-registration plan. For the evolution knowledge battery, we found that 85% of our participants scored less than 70%. This is significantly more than a quarter of the sample (exact proportions test, p < .001). For the Ordinary Science Intelligence scale, we found that 74% of our participants scored less than 70%. This is significantly more than a quarter of the sample (exact proportions test, p < .001).
