Randomized Controlled Trial
Effect of exposure to good vs poor medical trainee performance on attending physician ratings of subsequent performances.
Competency-based models of education require assessments to be based on individuals' capacity to perform, yet the nature of human judgment may fundamentally limit the extent to which such assessment is accurately possible. ⋯ In an experimental setting, attending physicians exposed to videos of good medical trainee performances rated subsequent borderline performances lower than those who had been exposed to poor performances, consistent with a contrast bias.
