Ontario boosted organ donor sign-ups by asking if drivers would take one

Ontario's organ-donor registration rate had plateaued for years despite standard awareness campaigns urging residents to sign up when renewing a driver's licence. The paper form asked people to consider donating in the abstract — a values-based, altruistic appeal that was easy to skip past on a routine bureaucratic errand.

Researchers partnered with ServiceOntario to test alternative wordings against the standard altruism appeal in a live renewal line, including one framed entirely around self-interest rather than generosity — a question rather than a request, aimed at people who had never been asked to imagine needing the thing they were being asked to give.

Researchers tested reframing the donor-registration prompt from an altruism ask to a reciprocity question — 'If you needed a transplant, would you have one?' — forcing renewers to weigh their own self-interest before declining. Ontario rolled the wording into its province-wide driver's-licence renewal form.

Reframed the prompt from an altruism ask to a reciprocity question — 'if you needed a transplant, would you have one?' — making the ask concrete and personal.

Asking 'if you needed a transplant, would you have one' made most renewers silently answer yes, creating felt inconsistency for those about to decline.

The reciprocity framing outperformed altruism appeals and process simplifications in the same trial, showing the psychological lever was key.

The intervention was a single reworded sentence on an existing form, requiring no new infrastructure or budget.

The low-friction renewal moment let the felt inconsistency translate directly into action.

When an altruistic ask plateaus, reframe it as a reciprocity question that forces people to imagine needing the thing themselves.

In the field trial (n=3,330), new registrations jumped from 4.1% to 7.4% of renewers, an ~80% relative increase, for the cost of a sentence. Ontario adopted a simplified registration form using the reciprocity prompt province-wide in 2016. The reciprocity prompt outperformed every other tested wording, including pure altruism appeals and process simplifications. Ontario adopted a simplified registration form using it province-wide in 2016; the researchers estimated the change could be worth roughly 225,000 additional registrations a year if sustained at scale.
