Reciprocity Principle

Reciprocity is a tendency to respond to help, gifts, or concessions with something in return. It can sustain mutual support and can also create pressure around unsolicited benefits. Expectations, timing, and strength vary across people and contexts.

A gift or concession can change a request by introducing a sense of obligation. That obligation may reflect a valued norm of mutual help, but its scope is not automatically set by the giver. An unsolicited sample does not establish consent to a purchase, and one useful favor does not imply unlimited access to someone's time.

Separate gratitude from the later decision. You can acknowledge help while checking whether the requested return is appropriate, proportional, and freely chosen. When offering help, clarify any expectations before the recipient accepts. Otherwise, a gesture presented as generosity can quietly become an undisclosed bargain.

When to use it

When building relationships that will need to support future collaboration; when negotiating and need to create movement; when evaluating whether your decisions are being influenced by unreciprocated obligations; when designing customer or stakeholder engagement strategies.

How it can help

Offer real value with clear expectations. When receiving help, distinguish appreciation from agreement to a later request, and assess that request on its own terms.
