The principle. Cialdini's first law: when someone gives us something, we feel pressure to give back. This is hard-wired — every culture on earth has it.
Why most reps blow it. They "give" generic stuff: a brochure, a free quote, a calendar link. None of those feel like gifts. They feel like work.
What actually triggers reciprocity.
- Specificity — A custom insight about their business. Not "here's our deck."
- Effort signal — They have to see you did work. "I pulled three of your competitors' pricing pages and noticed something."
- Unconditional first — Don't ask for anything in the same breath. The ask comes later, after the gift has time to land.
On a sales call. Open with a real teardown of their current setup. "Before we get into anything, I noticed your follow-up cadence is missing the 4-day touch — that alone is probably costing you 12% of your inbound." Now they owe you a hearing.
Watch out for. Reciprocity weaponized = manipulation. The gift has to be real. If they smell a setup, the debt flips into resentment.
