This article critically examines the Rational Choice Theory (RCT) in the context of crime prevention. Originating in classical criminology, RCT suggests that individuals weigh the costs and benefits before engaging in criminal behavior. The paper outlines the theory's assumptions, real-world applications, and empirical support. It also discusses major criticisms and proposes combining RCT with other criminological theories like Routine Activity Theory and Social Learning Theory to enhance its effectiveness.
