The attraction effect occurs when a third option is added to two seemingly equivalent options but it competes against only one of the original options. This increases the likelihood of the dominating option being chosen. In attraction effect studies, it is assumed that both attributes of the options are of equal importance to the decision maker. We aimed to examine whether attribute preference would affect the occurrence of the attraction effect when choosing financial products. A total of 487 undergraduate students were randomly assigned to groups with the financial product choice of two or three options. We found that when participants had no clear attribute preference the attraction effect occurred more frequently. Those with a clear preference for one attribute succumbed to the effect only when choosing a product unfamiliar to them. The research sheds light on two conditions of the attraction effect: the product familiarity and the attribute preference.

金融产品选择：属性偏好是否有助于避免吸引效应？

当第三个选项被添加到两个看似等效的选项中，但它只与原始选项中的一个竞争时，就会发生吸引力效应。这增加了选择主导选项的可能性。在吸引力效应研究中，假设选项的两个属性对决策者同等重要。我们旨在考察在选择金融产品时，属性偏好是否会影响吸引力效应的发生。共有 487 名本科生被随机分配到具有两个或三个选项的金融产品选择的组中。我们发现，当参与者没有明确的属性偏好时，吸引力效应发生得更频繁。那些对一个属性有明显偏好的人只有在选择了一种他们不熟悉的产品时才会屈服于这种效果。
