All over the world, private and public institutions have been attracted
to "nudges," understood as interventions that preserve freedom of
choice, but that steer people in particular directions. The most
effective nudges are often "defaults," which establish what happens if
people do nothing. For example, automatic enrollment in savings plans is
a default nudge, as is automatic enrollment in green energy.
Default rules are in widespread use, but we have very little information
about how people experience them, whether they see themselves as
manipulated by them, and whether they approve of them in practice. In
this book, Patrik Michaelsen and Cass R. Sunstein offer a wealth of new
evidence about people's experiences and perceptions with respect to
default rules. They argue that this evidence can help us to answer
important questions about the effectiveness and ethics of nudging.
The evidence offers a generally positive picture of how default nudges
are perceived and experienced. The central conclusion is simple:
empirical findings strongly support the conclusion that, taken as such,
default nudges are both ethical and effective. These findings, and the
accompanying discussion, have significant implications for policymakers
in many nations, and also for the private sector.
