Run, don't walk, to get the new free e-book from Network for Good, Homer Simpson for Nonprofits (PDF; registration required).
You'll get detailed knowledge from behavioral economics, applied to fundraising. Things like:
- The left brain need not apply.
- Stick to social norms, not market norms.
- Small, not big.
- Hope, not hopeless.
- Peer pressure still works.
- We listen to authority.
- The more you ask for, the more you get.
This is stuff that will make you a better fundraiser.
