Behavioral Science

Behavioral science is an interdisciplinary field that studies human and animal behavior by drawing on psychology, sociology, anthropology, economics, and related disciplines to explain why people act as they do. The term gained prominence in the mid-twentieth century, when researchers sought empirical, observable approaches to studying conduct rather than relying on speculation about inner mental states. B. F. Skinner’s operant conditioning and Ivan Pavlov’s classical conditioning provided foundational models of learned behavior, while Albert Bandura showed that observation and imitation also shape action. Within sociology, George Homans’ exchange theory and Erving Goffman’s analysis of interaction demonstrate how behavior is patterned by social context, norms, and reciprocal expectations. More recently, Daniel Kahneman and Amos Tversky’s work on heuristics and biases, and Richard Thaler and Cass Sunstein’s nudge theory, have extended behavioral science into public policy, health promotion, and economics. Critics argue that it can overemphasize individual choices at the expense of structural inequality, a concern often raised by sociologists. Behavioral science nevertheless remains influential for understanding decision-making, habit formation, social influence, and the design of interventions that encourage prosocial change.
