Several behavioural models of choice assume that decision makers place more weight on attributes where options differ more, an assumption we test in a set of experiments. We find that subjects are more likely to choose an option when we add options increasing the maximal difference in the original option’s strongest attribute, suggesting that the decision maker’s focus is drawn to attributes with a high spread. Additional experiments corroborate this finding. Still, we document that the focusing effect diminishes when options are presented using numbers instead of graphs or when subjects are forced to wait before submitting their answers.

差异吸引：关注经济选择的实验研究

几种选择的行为模型假设决策者更重视选项差异更大的属性，这是我们在一组实验中测试的假设。我们发现，当我们添加选项以增加原始选项最强属性的最大差异时，受试者更有可能选择一个选项，这表明决策者的注意力被吸引到具有高传播的属性上。额外的实验证实了这一发现。尽管如此，我们记录到，当使用数字而不是图表呈现选项时，或者当受试者在提交答案之前被迫等待时，聚焦效果会减弱。
