Nudge
What is Nudge?
A nudge is a small change in how choices are presented that steers behavior without banning options or changing incentives.
Examples include automatically enrolling employees in retirement savings (with opt-out) or placing healthy food at eye level. Nudges work with predictable biases to improve decisions while preserving freedom of choice.
Nudge: a worked example
Brightwell Manufacturing keeps the same plan, the same employer match, and the same paperwork, and changes only the default. Under the old opt-in form, 84 of 300 new hires enrolled in the retirement plan, or 28%. After the switch to automatic enrollment at 3% of pay with a one-page opt-out, 261 of 300 enrolled, or 87%. No option was removed and no payoff changed. With an average salary of $40,000, each new enrollee saves 3% of $40,000, or $1,200 a year, so the 177 extra savers put away $212,400 more annually.
The mistake students make with nudge
Students label any policy that changes behavior a nudge, including soda taxes, cigarette bans, and subsidies. A nudge has to leave every option open and leave the payoffs untouched; it only changes presentation. A tax on sugary drinks changes the price you pay, so it is an incentive, not a nudge. Moving bottled water to the front of the cooler is a nudge. The two get merged because they target the same behavior, but only one of them changes what the choice costs.
Nudge questions
What is an example of a nudge in everyday life?
Everyday nudges include a printer set to double-sided by default, a cafeteria that puts fruit at the register and cookies across the room, and a checkout screen that pre-selects the standard shipping option. Each keeps every option available; you can print single-sided, buy the cookie, or pay for overnight delivery. What changes is the effort and attention the alternative demands, which is enough to move a large share of choices.
Are nudges manipulative?
Nudges attract the manipulation objection because they work through inattention and habit rather than argument. The standard reply is that no default is neutral: a form has to say something, and whoever wrote the old version picked a default too. The usual test has two parts, whether the nudge would still work if it were announced openly, and whether opting out is genuinely quick and obvious.
What is the difference between a nudge and a mandate?
A nudge changes the default or the presentation, while a mandate removes the choice. Automatically enrolling workers in a savings plan they can leave with one form is a nudge; requiring every worker to contribute 3% of pay is a mandate. The practical test is the cost of opting out. If leaving takes a lawyer, a fee, or a fine, the policy is a rule wearing a friendlier name.
