Does nudging work?

In the wake of Thaler and Sunstein's seminal work 'Nudge' in 2008, the landscape of decision-making underwent a significant transformation. Organizations and governments eagerly embraced nudges, those subtle prods drawing from behavioral economics, as potent tools to shape people's choices. Yet, as the allure of nudges grew, so did questions about their long-term efficacy.

Our recent inquiry sought to unravel the enduring impact of these nudges on behavior. While they excel at prompting initial decisions, such as opting for default choices or sidestepping decoys, their influence tends to fade over time. Participants nudged towards specific options showed diminished engagement in the long run, compared to those who made independent choices.

This raises intriguing questions about the staying power of nudges in fostering lasting behavioral change. A telling example comes from a 2012 study attempting to boost healthy snacking habits. Despite initial enthusiasm, nudged choices failed to sustainably alter behavior.

Our subsequent investigations into popular nudges like default options and compromise alternatives unveiled a nuanced picture. While nudges effectively shape initial decisions, they struggle to maintain long-term engagement.

For instance, in one experiment, we observed that participants nudged towards default options showed a significant drop in usage over eight months compared to those who made unaided choices. A similar pattern emerged with decoys, where participants quickly gravitated away from the intentionally inferior option but also exhibited reduced long-term engagement.

Even the compromise effect, a widely observed tendency to opt for moderate choices, failed to guarantee sustained engagement. Participants who chose via compromise options exhibited a significant decline in usage over nine months compared to those who made straightforward choices.

These findings carry profound implications for policymakers and organizations championing nudges as panaceas for behavior change. While nudges undoubtedly hold value in shaping initial decisions, our research underscores the importance of supplementing them with complementary strategies to ensure sustained impact.

In light of these insights, governments and organizations are urged to adopt a holistic approach, combining nudges with other interventions to foster enduring behavioral change. By doing so, they can navigate the complexities of decision-making and chart a course towards more effective and sustainable outcomes.
