Information Processing and Commitment
研究发现，对初始意见的承诺会导致人们忽视新信息，从而降低最终信念的准确性，这源于内在的一致性需求。
Beliefs are often found to be sticky and rather immune to new information. In this article, we highlight a specific mechanism that raises resistance to incorporate new information. We provide causal evidence that commitment to a first opinion leads to a neglect of new and challenging information. Being asked to write down an initial estimate before additional information is obtained significantly and substantially reduces the accuracy of final beliefs. Investigating the sources of this effect, we show that our findings are well explained by an internal desire to act consistently.
