Tools for public health policy: nudges and boosts as active support of the law in special situations such as the COVID-19 pandemic.

ABSTRACT

In recent years, "nudging" has become a standard behavioral intervention at the individual level and for the design of social policies. Although nudges are effective, such interventions seem to be limited to a given space and time, and there is only scant evidence to support the contrary view. On the other hand, choice architects may utilize another type of intervention called "boosting," which shows the promise of generalized and lasting behavioral change. A government can use these tools to shape public policy. Behavioral interventions such as policy-making tools have their boundaries, as does the law. We argue that nudging and boosting may serve as active local or global aids in support of the legal system under certain circumstances. Nudging and boosting can also support the legal system, especially in relation to emerging social issues or events that are unprecedented, such as the recent global COVID-19 pandemic, where certain behavioral patterns are expected, but it would be difficult or impossible to enforce them through the law alone.
