Decision Theory

Decision Theory is the interdisciplinary study of how choices are made under conditions of certainty, risk, and uncertainty. Drawing upon economics, mathematics, psychology, statistics, philosophy, and operations research, Decision Theory provides conceptual frameworks for evaluating alternatives, balancing trade-offs, and selecting courses of action when outcomes cannot be known with complete confidence.

Classical Decision Theory assumes that individuals act rationally by maximizing expected value. Behavioral Decision Theory recognizes that real-world decision-makers are influenced by cognitive bias, incomplete information, emotions, organizational pressures, and bounded rationality. Modern business decision-making integrates insights from both perspectives by combining structured analytical methods with an understanding of human judgment.

Decision Theory does not prescribe a single method for making decisions. Instead, it provides a foundation for understanding why different approaches are appropriate under different conditions.
