Changemakers.net is organizing an online, open source competition as a global search for individuals and institutions who help people make better decisions regarding their health and the health of others. Designing settings and scenarios in which people make healthy choices requires presenting those choices in a way that takes the all-too-human side of decision making into account. People need (and want) choices, but they also need (and want) help’”a nudge’”when they’re not sure what to do.
