Nudges in public policy

For about two decades, "nudges" have been used in public policy to guide behavior through small environmental changes. These interventions, such as placing a fly in a urinal or coloring stairs near escalators, aim to influence decisions without direct instruction or prohibition.

Debate on nudges' effectiveness

A debate is emerging in the field of behavioral sciences about whether these nudges can create lasting behavioral change or if they are limited to short-term effects. An alternative approach, known as "boost," is gaining attention. This method focuses on strengthening individuals' decision-making abilities and autonomy rather than relying on automatic responses.

Boost approach and its goals

According to researchers Ralph Hertwig and Till Grüne-Yanoff, the boost approach provides tools that allow individuals to make better decisions over time. Unlike nudges, which act on automatism, boosts aim to build skills that can be applied in various situations. For instance, in the context of public transport, the Nudge Unit of Transilien-SNCF Voyageurs has been exploring the interaction between nudges and boosts.

Practical applications of boosts

One application involves helping travelers understand and anticipate train positioning by providing visual clues, which not only guides behavior but also develops recognition skills that can be reused elsewhere. Another example is the management of forgotten items. Instead of constant reminders, the teams sought to activate collective vigilance and solidarity by emphasizing values such as attention to others and a sense of responsibility.

Introducing the concept of care

In addition to nudges and boosts, the Nudge Unit introduces a third dimension: "care," inspired by the work of political science professor Joan Tronto and philosopher Cynthia Fleury. This concept emphasizes kindness and the consideration of vulnerabilities. In transportation, this means creating environments that promote mutual attention and helping each other.

Nudge Unit's impact and anniversary

The Nudge Unit of Transilien has been in service for 10 years and has become a recognized reference in the application of behavioral sciences within business and public transport. It remains the only entity dedicated to innovation through behavioral sciences within French companies and is registered in the BI Units register of the OECD. This year, the Nudge Unit is celebrating its 10th anniversary with a major event at La Gaîté Lyrique on November 26th, focusing on the subject "What response do behavioral sciences offer to the challenges of coexistence in transportation?" The event will be hosted by behavioral scientist Nicolas Fieulaine and journalist Charlotte Dekoker, with the presence of Jean Castex, CEO of the SNCF Group, and Alain Ribat, Transilien Director.
