Nudging

What is nudging?

Nudging is the use of nudges: changes to the presentation or arrangement of choices that aim to influence behavior without removing alternatives or substantially changing financial incentives.

Nudging consumer behavior: examples

A shop might change which options customers encounter first while keeping the full range available. A service might remind customers to finish an application they started. These illustrate ways to change a choice environment; they do not establish that the change will work or benefit the customer.

To evaluate a consumer nudge, distinguish the business’s aim from the customer’s interests. More purchases or completed forms do not, by themselves, show a better decision. The design should also be assessed for misleading presentation or obstacles to declining. For business and government examples with measured results, see nudge theory.

What can be concluded from the evidence?

Judge the specific intervention and the result it produces. In a large analysis of randomized trials from two nudge units, average effects were modest and smaller than those in an academic comparison sample. A publication-bias reanalysis of a separate broad meta-analysis challenged the evidence for a general pooled benefit.

These results warrant caution about broad claims. They do not imply that every reminder or default has no effect. Nor does an effect on a recorded choice establish a lasting change in habits, preferences, or wellbeing. Those outcomes need their own measures and follow-up.
