Coined by economist and political scientist Herbert A. Simon in the 1940s and 1950s, bounded rationality challenges the classical economic assumption of a fully informed, utility-maximizing homo economicus. Simon argued that real human and organizational decision-makers face three persistent constraints: incomplete information about alternatives and their consequences, limited cognitive ability to process that information, and finite time in which to decide. Because optimization under these conditions is impossible, agents instead "satisfice" — they search until they find an option that meets an acceptable threshold, then stop.
Simon developed the concept in works including Administrative Behavior (1947) and Models of Man (1957), and it was central to the citation for his 1978 Nobel Memorial Prize in Economic Sciences. The framework reshaped multiple disciplines:
- Behavioral economics: Daniel Kahneman and Amos Tversky's work on heuristics and biases (prospect theory, 1979) built on Simon's premise that actual cognition diverges from expected-utility models.
- Organization theory: James March and Simon's Organizations (1958) used bounded rationality to explain standard operating procedures, routines, and incremental decision-making in firms and bureaucracies.
- International relations: Graham Allison's Essence of Decision (1971), analyzing the Cuban Missile Crisis, drew on bounded rationality to construct the Organizational Process and Governmental Politics models as alternatives to the Rational Actor model.
- Public policy: Charles Lindblom's "science of muddling through" (1959) described policymaking as disjointed incrementalism — a direct application.
For MUN delegates and IR researchers, the concept is useful when explaining why states adopt suboptimal policies, why negotiators rely on focal points and analogies, and why bureaucratic outputs often reflect routine rather than strategic calculation. It does not claim actors are irrational; it claims rationality is procedural and constrained, not substantive and unlimited.
Example
In analyzing the 2008 financial crisis, regulators cited bounded rationality to explain why mortgage investors relied on credit-rating shortcuts rather than independently evaluating complex mortgage-backed securities.
