Everyone defaults to one of three reciprocity styles

Grant's framework sorts interpersonal exchange into three habitual styles. Takers try to get more from interactions than they give, prioritizing their own interests even at others' expense. Matchers operate on a norm of fairness, helping others roughly in proportion to what they expect to receive back, tit for tat. Givers contribute to others' success without expecting an immediate or equivalent return, often helping without being asked.

Most people, Grant notes, aren't purely one type across every context — someone might be a matcher at work and a giver with close friends — but tend to have a dominant default style that shapes the majority of their professional interactions and reputation over time.

This three-way framework matters because it reframes workplace success not just as a function of skill or effort but of how a person habitually handles the exchange of favors, credit, time, and information with colleagues — a dimension often overlooked in conventional career advice.

Takeaway: notice your own default reciprocity style, since it shapes your reputation as much as your actual skill does.
