Autoenrollment

What is autoenrollment?

Autoenrollment makes participation in a program the default. The person is enrolled unless they select an alternative; in an opt-out arrangement, they can decline or change the default.

How it works

Madrian and Shea studied a US employer’s 401(k) plan after automatic enrollment was introduced. Participation increased, and many employees stayed with the default contribution rate and investment allocation.

What changed?

The enrollment arrangement changed. Employees did not necessarily make an active decision to start saving or develop a savings habit. That is the distinction this site makes between impact and active behavior change.

It matters when judging a result. Participation, contribution levels, investment choices, and long-term financial outcomes answer different questions. An enrollment total cannot stand in for all of them.

Autoenrollment can also describe arrangements for health insurance or employee benefits. In each case, ask what participation actually provides, what information is shared, and which costs or commitments begin automatically. A label borrowed from retirement saving does not establish that another program benefits its members.

The default’s terms and the ease of leaving also matter. A program should make clear what is happening and what alternatives people have. The same care is needed with organ donation: registration or presumed consent differs from an actual donation, and a retirement-plan study cannot establish that outcome.
