Abstraction	Subdomain	Description
Behavioural design		The intentional design of artifacts, services, communications, or environments to influence specified human behavior through behaviorally informed features and accountable evaluation.
Contingent cooperator		An agent willing to contribute to a collective good when enough others are observed or expected to cooperate, but not unconditionally.
Denomination Effect		The denomination effect is a change in spending behavior when equal cash value is packaged as one large unit rather than several smaller units.
Expenditure cascades	—	A consumption spillover in which higher spending by top-income households raises local comparison standards and induces successive spending increases down the income distribution.
Homo reciprocans	—	An economic actor model in which people reward cooperation and punish unfairness even when doing so yields no foreseeable material gain.
Nudge Theory		A choice architect changes defaults, salience, or comparison cues to shift behavior while keeping meaningful alternatives and material incentives in place.
Present bias		Present bias is the disproportionate preference for immediate payoff when a choice becomes imminent, producing time-inconsistent reversals relative to preferences expressed for the same delay at an earlier date.
Quantal response equilibrium		A game-theoretic fixed point in which each player's action probabilities respond smoothly and positively to expected payoffs while beliefs are consistent with those same probabilistic choices.
Uncertainty effect	—	A choice anomaly in which a known lottery is valued below its least valuable possible outcome.
