Choice behavior refers to the observable process through which an individual selects one option from a set of available alternatives ^[1][2]. It reflects the interaction of preferences, beliefs, goals, perceived attributes, constraints, and the decision environment, including how options are presented and what information is available ^[1][2]. In decision sciences, choice behavior is studied through the alternatives selected and, where relevant, the decision strategies and cognitive processes underlying selection ^[2][3]. Choices may be modeled as deterministic outcomes of stable preferences or as probabilistic responses shaped by uncertainty, limited information, context, and individual differences ^[1][3]. The concept is distinct from decision-making more broadly: decision-making may include problem identification, information search, deliberation, and evaluation, whereas choice behavior focuses on selection among alternatives and the factors that systematically influence it ^[2][3].
