Equal words, unequal exchange
Social Exchange Theory shows how repeated benefits, costs, obligations, alternatives, and resource asymmetries can make the same communication collaborative in one relationship and extractive in another
Premise
A request, favor, refusal, acknowledgment, or silence can become one move in a longer exchange history. Social Exchange Theory explains how repeated social consequences create expectations, obligations, dependence, and power. Its executive value lies less in treating people as calculators than in showing why communication cannot be interpreted apart from what participants receive, risk, owe, or can obtain elsewhere.
The tradition is a family of related formulations, not one equation. Homans emphasized consequences and repeated interaction; Thibaut and Kelley analyzed interdependence, comparison standards, and alternatives; Blau connected voluntary benefits, diffuse obligation, trust, dependence, and power. Keeping those mechanisms distinct prevents “reciprocity” from becoming a catch-all explanation.
