You may not realise it, but \u201cnudge\u201d has been used by businesses, policy-makers and governments for years to prod the public into making different choices. Small changes in our environment can \u201cnudge\u201d us into different behaviours without restricting the options available to us. For example, printing the low-calorie options in bold on a menu, or showing the calorie information, might change what we choose to eat. But does the public support this? And how do subtleties in how \u2018nudge\u2019 interventions are designed affect support, if at all? Research led by the Universities of G\u00f6ttingen and Bonn set out to examine public support for nudge scenarios with different design variations, each aimed at promoting healthy and\/or sustainable food choices. The researchers showed there were two promising ways to improve public support for nudging strategies: reducing the effort people must expend to avoid the nudged option they would usually want to follow; and improving the transparency of the nudge. The results were published in BMC Public Health.<\/em><\/p>\n

People can be nudged to make a certain choice by making it the default option. For instance, rather than offering butter automatically at a restaurant by default, restaurants could make it so that butter is only available upon active request. This type of nudge \u2013 known as a \u201cdefault nudge\u201d \u2013 can be effective, but it can be unpopular relative to other nudging strategies. Researchers set out to analyse consumer reaction by conducting an online survey on a sample (N = 451) of German adults, who were presented with five nudge scenarios and prompted to rate their support for each. Participants were also asked in each scenario to indicate what their typical behaviour would be (i.e., would you usually eat butter in a restaurant), the extent to which they perceived the nudge to intrude upon their freedom of choice, and how effective they believed the nudge would be. Participants then answered the same questions for a variation of each nudge scenario in which one aspect of the design was changed, allowing the researchers to pinpoint how these design variations affected public support.<\/p>\n

The researchers discovered that some designs were more promising than others for improving public support. For instance, reducing the effort needed to opt out of the nudged option \u2013 such as by presenting vegetarian dishes on the first pages of a menu followed by meat dishes, rather than providing only a vegetarian menu on the table with a menu with meat options available on request \u2013 increased support. Similarly, increasing the transparency of the nudge itself, such as by asking participants whether they preferred a pre-filled \u2018climate friendly\u2019 online grocery cart rather than simply offering it by default, increased support. With regard to predicting the level of support, the perception that nudges intruded upon free choice was the most important driver of non-acceptance, whereas the perception of effectiveness was the most salient driver of acceptance.<\/p>\n

\u201cUnderstanding public support \u2013 and its drivers \u2013 is important for designing politically viable, ethical, and effective nudges,\u201d says first author Simone Wahnschafft at G\u00f6ttingen University\u2019s Sustainable Food Systems research group. \u201cWe were surprised to find that the personal circumstances of our participants and whether their own behaviour would be affected by the nudge had little effect on their support. We found that the perception of upholding free choice and of effectiveness were key to public support.\u201d This study opens up avenues for future research into how \u2018sweet spots\u2019 can be found for default nudges that are both effective and widely supported.<\/p>\n
