Three insights derived from behavioral economics that nonprofits can use:
Small, Not Big–The bigger the scale of what you’re communicating, the smaller the impact on your audience.
Hopeful, Not Hopeless–People tend to act on what they believe they can change. If your problem seems intractable, enormous, and endless, people won’t be motivated to help.
Peer Pressure Still Works–People are more likely to do something if they know other people like them are doing it.
