Increasing Organ Donor Registrations with Behavioral Interventions: A Field Experiment
A ten-word reciprocal question almost doubles on-the-spot organ-donor sign-ups in busy service centers.
01Research in Context
What this study did
Robitaille et al. (2021) ran a real-world trial at ServiceOntario kiosks. They asked customers a single question before offering donor cards.
Half the customers heard: "If you needed a transplant would you have one?" The other half got the usual pitch. Staff also cut extra steps for some people.
What they found
The reciprocal question almost doubled sign-ups, from 4 % to 7 %. Making the form shorter added a small extra bump.
The gains held across busy city counters and quiet rural offices.
How this fits with other research
van Schrojenstein Lantman-de Valk et al. (2006) got shoppers to drop food-bank items at the grocery till with a tiny shelf sign. Same idea: prompt right where the person already has a wallet out.
Cooper et al. (1990) posted AIDS facts above free condom bowls in bars and saw a 47 % jump in take-aways. Again, a cheap sign moved a health behavior.
These studies look different on the surface—food, condoms, organ cards—but all show one clear rule: place a short, values-based prompt at the exact moment of choice.
Why it matters
You can borrow the reciprocal line tomorrow. Before a parent signs consent for assessment, ask, "If your child needed help, would you want someone to provide it?" Then offer the consent form. The same nudge may lift treatment agreement, survey return, or session attendance with zero extra cost.

03Original abstract
Although prior research has advanced our understanding of the drivers of organ donation attitudes and intentions, little is known about how to increase actual registrations within explicit consent systems. Some empirical evidence suggests that costly, labor-intensive educational programs and mass-media campaigns might increase registrations; however, they are neither scalable nor economical solutions. To address these limitations, the authors conducted a field experiment (N = 3,330) in Ontario, Canada, testing the effectiveness of behaviorally informed promotion interventions as well as process improvements. They find that intercepting customers with materials targeting information and altruistic motives at the right time, along with streamlining customer service, significantly increased registrations. Specifically, the best-performing intervention, prompting perspective taking through reciprocal altruism (“If you needed a transplant would you have one?”), significantly increased new registration rates from 4.1% in the control condition to 7.4%. The authors followed up with seven posttests (total N = 3,376) to find support for their theoretical predictions and to explore the mechanisms through which the interventions may have operated. This article provides evidence for low-cost, scalable marketing solutions that increase organ donor registrations in a prompted choice context and has important implications for public policy and societal welfare.
