How do you nudge people to register as organ donors? Studies said 8/10 people were positive, but far from 8/10 were enrolled.

So, we decided to try something new. Instead of framing donation as something you do for someone else, we decided to remind people of the gift of life. A gift you’ve already received and keep receiving every day.

This approach, in combination with supportive statistics, was successful. Leading to a clear spike in enrollment during and after the campaign.
