The study tested a new way of setting defaults called "reason defaults" to help people make better decisions, especially those with different preferences. Reason defaults explain why a certain option is chosen and who might want to choose differently. In five studies with over 4,000 adults, reason defaults were found to be more helpful than standard defaults or forced choices. They guided most people to the best option while also helping those with minority interests choose differently. Participants also said that reason defaults made decisions clearer, easier, and more transparent compared to standard defaults and forced choices.
