Use the Ben Franklin Effect to Build Alliances

Robert Franklin discovered that doing favors for a political rival flipped attitudes: one note to borrow a book sparked a genuine friendship. Modern psychology calls this the Ben Franklin Effect. When you ask someone—especially a busy weak tie—for a small, specific favor, that person starts to like you more. Their brain reasons, “I must like this person since I’m helping them,” and next time they’re more inclined to say yes again. So instead of cold-calling for big requests, flip the script: start small, then build. That little nudge builds rapport and trust faster than any elevator pitch or résumé drop.

This works because our attitudes follow our actions, not just the other way around. When someone helps you, dopamine spikes and their brain rewards them with a sense of purpose and well-being. A simple, well-crafted request and heartfelt thanks can launch a chain of favors that deepen relationships and unlock doors in surprising ways.

Think of one busy professional whose insights you value, ask for a one-minute favor—maybe pointing to one article or fact—and send a genuine thank-you that explains exactly how it helped. You’ll spark the Ben Franklin Effect, turning that small request into goodwill, rapport, and future collaboration—try it this afternoon.
