In the psychology of motivation, balance theory is a theory of attitude change, proposed by Fritz Heider. It conceptualizes the cognitive consistency motive as a drive toward psychological balance. The consistency motive is the urge to maintain one's values and beliefs over time. Heider proposed that "sentiment" or liking relationships are balanced if the affect valence in a system multiplies out to a positive result.

[[Frank Harary]] and Dorwin Cartwright looked at Heider's triads as 3-cycles in a [[signed graph]]. The sign of a [[path (graph theory)|path]] in a [[graph (discrete mathematics)|graph]] is the product of the signs of its edges. They considered [[cycle (graph theory)|cycle]]s in a signed graph representing a social network.
