Average correlations between IAT D-scores, and both IAT score predictions and Thermometer ratings by study.

Within-subject correlations are computed for each participant and then averaged across all participants in one study, or across all 430 participants in the last row. Between-subject correlations are computed per IAT and then averaged across 5 IATs per study. Thermometer ratings are simple scores in Studies 1 and 2, but reverse-scored here for easier comparability. Thermometer ratings in Studies 3 and 4 are computed as difference scores comparable to the IATs. Predictions are made on discrete 7-point scales (1–7) in Studies 1 and 2, and on continuous 61-point scales (1.0–7.0) in Studies 3 and 4. All average correlations presented here are significant at p<.05 (except the within-subject Thermometer-IAT correlation in Study 1).
