Seven reasons people say yes. Try one today.
01
Reciprocity
People feel obliged to return what they’ve been given.
Try: Give first, and make it personal and unexpected.
02
Liking
We say yes to people we like and feel similar to.
Try: Find a genuine commonality before you make the ask.
03
Unity
We say yes to people we see as one of “us.”
Try: Speak to shared identity: “we,” not just “you.”
04
Authority
We follow credible, knowledgeable experts.
Try: Establish your expertise before you make your case.
05
Social Proof
When unsure, we look to what similar others do.
Try: Show what peers like them have already chosen.
06
Consistency
We act in line with what we’ve already said or done.
Try: Ask for a small, active, voluntary yes first.
07
Scarcity
We want more of what’s rare or about to be lost.
Try: Explain what’s unique, and what they’d miss without it.
