Exercised: The Science of Physical Activity, Rest and Health

by Daniel E. Lieberman

To be honest, I had qualms about Henrik’s approach. Philosophically, I classify myself as an admirer of “libertarian paternalism,” the idea that companies, governments, and other institutions should help us act in our own best self-interests while respecting our freedom of choice.4 Libertarian paternalists favor nudges over coercion. Instead of forcing people to exercise, libertarian paternalists provide incentives. Rather than relying on us to “opt in” to be organ donors or tip waiters, libertarian paternalists ask us to “opt out” of these programs or have credit cards automatically remind us to tip when we pay the bill.
