Do Evaluations Rise With Experience?
研究发现,在序列评估中,后续的评分往往比前面的更积极,这种偏差在舞蹈比赛、大学课程评分和实验中都存在,原因是重复评估使决策更流畅。
Sequential evaluation is the hallmark of fair review: The same raters assess the merits of applicants, athletes, art, and more using standard criteria. We investigated one important potential contaminant in such ubiquitous decisions: Evaluations become more positive when conducted later in a sequence. In four studies, (a) judges' ratings of professional dance competitors rose across 20 seasons of a popular television series, (b) university professors gave higher grades when the same course was offered multiple times, and (c) in an experimental test of our hypotheses, evaluations of randomly ordered short stories became more positive over a 2-week sequence. As judges completed repeated evaluations, they experienced more fluent decision making, producing more positive judgments (Study 4 mediation). This seemingly simple bias has widespread and impactful consequences for evaluations of all kinds. We also report four supplementary studies to bolster our findings and address alternative explanations.
