Reciprocity

Give something of value first to create a felt obligation that increases the chance of a return concession.

Robert CialdiniInfluencemoderatePersuasion Principle

Reciprocity is the deepest social norm Cialdini identified: when someone gives us something — information, a concession, a favour, even a small gift — we feel an internal pressure to give something back, often disproportionate to what we received. In negotiation, the move is to make the first meaningful concession or contribution, especially one tailored to the counterpart's interests, before asking for anything in return.

Example

You

"I know the design fee is normally non-negotiable — I'm going to absorb it on this one because I want this collaboration to work. What can you do for me on the timeline?"

Counterpart

(visibly recalibrating) "Let me see if I can move us to twelve weeks."

When to use

Use reciprocity when you want to break an impasse, when the counterpart has been guarded with information, at the start of a long-term relationship to seed goodwill, and when your concession can be made to feel personalised rather than transactional.

When NOT to use

Avoid it when the counterpart is openly transactional and immune to the obligation (procurement professionals are trained against this), when your gift can be perceived as a bribe, and when you cannot afford the concession without signalling weakness.

How to counter this

Acknowledge the gift warmly, then explicitly reset: "That's very generous — but our two issues are independent, so let's look at the timeline on its own merits." Naming the move dissolves the obligation.

List your last three negotiations. For each, identify one low-cost concession you could have made first that would have created reciprocity. Plan one for your next negotiation.
