Abstract
The Ss estimated posterior probabilities for a series of problems which had varied a priori probabilities of the datum and likelihood ratios to determine if subjective estimates are influenced by the probability of the datum. No such influence was found in this study or in its subsequent replication, and these results are compared to another study which found an effect.
