Living and Learning: The Interplay between Beliefs, Sampling Behaviour, and Experience
(English)Manuscript (preprint) (Other academic)
The effects on performance of selective feedback contingent on the decisions of the individual were investigated, and the prediction that negative effects of selective feedback are mediated by sampling behaviour that produces a sample of experience that apparently confirms an initial incorrect belief. Empirical results demonstrated that negative effects on performance of selective feedback were small. However, when participants were offered an incorrect prior assumption concerning the likely outcomes of their decisions, and the aim was to produce good outcomes, selective feedback lead to a restrictive sample of experiences that confirmed the incorrect assumption. Consequently, mistaken beliefs persisted, even after accurately perceived and interpreted extensive experience. In contrast, when the decision maker was encouraged to sample more liberally, objective experience allowed the revision of an incorrect assumption. Finally, the estimated base-rates of participants with selective feedback supported the predictions from constructivist coding.
