  1. Text DA (Discomfort with Ambiguity), text AB (Absolutism), and text NC (Need for Complexity and Novelty) were calculated as free-text responses obtained from open-ended questions adopted from the DA, AB, and NC questions, respectively. The correlation coefficients in the table show the median correlation coefficients between the predicted values and true ones for the five test sets in the outer loop (n = 591/5 = 118 or 119). All texts were calculated by combining these three questions. *** p < 0.001, ** p < 0.01, * p < 0.05, † p < 0.10.
