Discrepancy Weights. The discrepancy weights depend on the relative reliability of the cues across the different reliability conditions. Discrepancy weights are inversely correlated to the probability of the common cause P _C. Thus, the lower discrepancy weight in the experiment 1.b indicates a higher probability of an assumed common cause, which is consistent with the observed behavior in that experiment. In contrast, the higher discrepancy weight in the experiment 1.a points to a lower common cause probability that explains the selection strategy in experiment 1.a.
