(a) Correlation between arbitration propensity and factor 1 score. Discovery sample: N = 943, Pearson’s r = −0.016, p = 0.629, two-tailed; replication sample: N = 352, Pearson’s r = −0.012, p = 0.819, two-tailed. (b) Correlation between uncertainty weight parameter η and factor 1 score. Discovery sample: N = 943, Pearson’s r = −0.031, p = 0.343, two-tailed; replication sample: N = 352, Pearson’s r = −0.018, p = 0.733, two-tailed. Error bands represent the 95% confidence interval.
