This paper experimentally investigates the effect of introducing unavailable alternatives and irrelevant information regarding the alternatives on the optimality of decisions in choice problems. We find that the presence of unavailable alternatives and irrelevant information generates suboptimal decisions with the interaction between the two amplifying this effect. Irrelevant information in any dimension increases the time costs of decisions. We also identify a “preference for simplicity” beyond the desire to make optimal decisions or minimize time spent on a decision problem.

本文通过实验研究了引入不可用的替代方案以及与替代方案无关的信息对选择问题中决策最优性的影响。我们发现，不存在的替代方案和不相关的信息的存在会产生次优决策，而两者之间的相互作用会放大这种效果。任何维度上不相关的信息都会增加决策的时间成本。我们还确定了“对简单性的偏好”，而不是做出最佳决策或将决策问题花费的时间最小化的期望。
