Outcomes Affect Evaluations of Decision Quality: Replication and Extensions of Baron and Hershey's (1988) Outcome Bias Experiment 1.

ABSTRACT: Outcome bias is the phenomenon whereby decisions which resulted in successful outcomes were rated more favorably than when the same decisions resulted in failures. We conducted a pre-registered replication and extension of Experiment 1 (original's: N = 20) from the classic Baron and Hershey (1988) with an online Amazon Mechanical Turk sample using CloudResearch (N = 692), switching from a within-participants design in the original experiment to a between-participants design. We tested outcome bias by measuring participants' ratings of the quality of decisions in medical scenarios. For the replication (pre-registered) part of the study, we successfully replicated signal and direction of the outcome bias (original: d_paired = 0.21 - 0.53; replication: d
