Corrigendum: Causal Inference About Good and Bad Outcomes.

As a preliminary manipulation check, we verified that participants’ beliefs about hidden causes varied with the outcome valence in a condition-specific manner (Fig. 2a). Participants were more likely to believe that a hidden cause resulted in negative outcomes, as opposed to positive outcomes, overall, t(71) = 4.71, p < .001, d = 0.55, 95% CI = [0.08, 0.20]. Importantly, participants were more likely to believe that the hidden agent had intervened after negative than after positive outcomes in the adversarial condition, t(71) = 17.56, p < .001, d = 2.07, 95% CI = [0.54, 0.67], and after positive than after negative outcomes in the benevolent condition, t(71) = −10.38, p < .001, d = 1.22, 95% CI = [−0.49, −0.33]. Participants were also slightly more likely to believe that the hidden agent had intervened after negative outcomes in the neutral condition, t(71) = 2.22, p = .03, d = 0.26, 95% CI = [0.01, 0.22]. We will revisit this effect in the context of our computational model.
