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

In recent years, "nudging" has become a standard behavioral intervention at the individual level and for the design of social policies.

On the other hand, choice architects may utilize another type of intervention called "boosting," which shows the promise of generalized and lasting behavioral change.
