The Dynamics of Motivated Beliefs
研究了在收到反馈后，动机性信念如何随时间变化：正面反馈影响持久，负面反馈短期有效但逐渐消退，并发现回忆不对称和准确性激励的作用。
A key question in the literature on motivated reasoning and self-deception is how motivated beliefs are sustained in the presence of feedback. In this paper, we explore dynamic motivated belief patterns after feedback. We establish that positive feedback has a persistent effect on beliefs. Negative feedback, instead, influences beliefs in the short run, but this effect fades over time. We investigate the mechanisms of this dynamic pattern, and provide evidence for an asymmetry in the recall of feedback. Finally, we establish that, in line with theoretical accounts, incentives for belief accuracy mitigate the role of motivated reasoning.
