We investigate how people make choices when they are unsure about the value of the options they face and have to decide whether to choose now or wait and acquire more information first. In an experiment, we find that participants deviate from optimal information acquisition in a systematic manner. They acquire too much information (when they should only collect little) or not enough (when they should collect a lot). We show that this pattern can be explained as naturally emerging from Fechner cognitive errors. Over time participants tend to learn to approximate the optimal strategy when information is relatively costly.

学会犹豫

我们调查当人们不确定他们面临的选择的价值并且必须决定是现在选择还是等待并首先获取更多信息时，他们如何做出选择。在一项实验中，我们发现参与者以系统的方式偏离了最佳信息获取。他们获得的信息太多（当他们应该只收集很少时）或不够（当他们应该收集很多时）。我们表明，这种模式可以解释为从 Fechner 认知错误中自然出现的。随着时间的推移，当信息相对昂贵时，参与者倾向于学习近似最佳策略。
