我们研究关于人们所关注的特质（智力和美貌）的客观信息的处理和获取。收到负面反馈的受试者不尊重这些信号的强度，他们的信息更新行为的可预测性要低得多，并且对新信息表现出厌恶。在收到好消息时，推断在准确性和精确性上都更符合贝叶斯规则。在我们的中性对照中，信号方向不影响信息更新或获取。与以往的研究不同，我们的设计独立地改变了方向以及与先验信息的一致性。结果表明，确认偏差是由方向驱动的；仅确认本身没有影响。（《经济文献杂志》分类号D82，D83）
We study processing and acquisition of objective information regarding qualities that people care about, intelligence and beauty. Subjects receiving negative feedback did not respect the strength of these signals, were far less predictable in their updating behavior and exhibited an aversion to new information. In response to good news, inference conformed more closely to Bayes' Rule, both in accuracy and precision. Signal direction did not affect updating or acquisition in our neutral control. Unlike past work, our design varied direction and agreement with priors independently. The results indicate that confirmation bias is driven by direction; confirmation alone had no effect.
