Abstract

Default nudges—making the desired option the standard option—are often criticized for hampering autonomy. However, laboratory research suggests this expectation of autonomy loss is not reflected in nudgees' experienced autonomy. In this study, we investigated whether this finding translates to a real-world setting by implementing a default nudge to increase food donations in the supermarket (Experiment 1). Upon entering the supermarket, customers were asked to donate a food item for charity and were handed a shopping cart/basket that was empty (control) or contained a food item meant for donation (default nudge). Donations were collected after checkout, and customers rated their experienced autonomy of their choice to donate. We replicated this study and added a vignette condition portraying the default nudge to measure expected autonomy for the same situation (Experiment 2). The results show the default nudge reduced participants' expected autonomy but not their experienced autonomy, shedding new light on the relation between nudging and autonomy. Furthermore, this novel form of the default nudge was found to be successful in increasing food donations in the supermarket, further expanding the field where this nudge has been successful.

默认暗示对经验自主和预期自主的影响:食物捐赠实地研究
默认推断使期望选项成为标准选项,常常被批评为妨碍自主性。然而,实验室研究表明,这种自主性丧失的预期并没有反映在被劝导者的自主性体验中。在本研究中,我们通过在超市中实施增加食物捐赠的默认劝导(实验 1),来研究这一发现是否可以转化到现实世界中。进入超市后,顾客被要求为慈善机构捐赠一件食品,并被递给一个空的购物车/篮子(对照组)或装有捐赠食品的购物车/篮子(默认暗示)。结账后收集捐赠物品,顾客对其选择捐赠的自主性进行评分。我们重复了这一研究,并增加了一个描述默认劝诱的小故事,以测量相同情况下的预期自主性(实验 2)。结果显示,默认暗示降低了参与者的预期自主性,但没有降低他们的体验自主性,这为我们揭示暗示与自主性之间的关系提供了新的线索。此外,实验还发现这种新颖形式的默认暗示成功地增加了超市中的食物捐赠,进一步拓展了这种暗示的成功领域。
