Note. Top panel compares predicted and actual answers for the study sample, and bottom panel compares predictions to actual answers in the nationally-representative dataset, using only items common to both datasets (no items in common for Ingroup judgments). Lib = Liberal participants, Mod = Moderate participants, Con = Conservative participants. Formulas used to calculate t, df, and d without assuming equal sample sizes or variances can be found in the supplement.
