Reciprocity Principle

Give first, fit the gift to the person, and never wave off a thank-you. The rule every culture teaches, used on purpose.

There's not a single society that fails to train its members from childhood in this rule. And that is that we are obligated to give back to others who have first given to us.

Disagreements

Trigger the rule, or read the person?

Robert Cialdini

treats influence as rules people already carry. Give first and the other side feels they owe you, at a negotiating table as much as in a restaurant. The work is picking the first move.

Chris Voss

argues that negotiation runs on emotion. Show you understand the other side's feelings and name them out loud. He calls this tactical empathy, and says it beats any logical argument or compliance trigger.
