Bounded Rationality

Herbert Simon coined the term bounded rationality in the 1950s as a counterposition to classical decision theory, which presupposes a rationally optimizing decision-maker. Simon’s insight: people do not maximize, they satisfice — they choose the first option that meets their minimum requirements, rather than systematically evaluating all options. Not from laziness but from structural necessity. Cognitive capacity, available information, and available time are limited.

Strategic Relevance

Bounded rationality is not primarily a psychological insight. It is the theoretical justification for why organizations need decision architecture. If decision-makers cannot optimize — and demonstrably they cannot — then the quality of organizational decisions depends not on the quality of individual decision-makers but on the conditions under which decisions are made.

The illusion of control roots directly in the non-acknowledgment of bounded rationality.

Common Misconceptions

The most widespread misconception: bounded rationality is an argument against rational deciding. It is an argument for better decision conditions. Second misconception: it only concerns operational decisions. Strategic decisions are subject to the same cognitive limits — often even more so. Third misconception: if people do not rationally optimize, their decisions are irrational. Satisficing is not irrational — it is an efficient heuristic under real conditions.

Decision Architecture Perspective

Bounded rationality provides the theoretical foundation for decision architecture as a design discipline. The architecture must fulfill three functions: reduce information overload to decision-relevant information, compensate cognitive biases through structural counterweights, and set the decision timing so that neither too early nor too late is decided.

Distinction

Bounded rationality is not the same as behavioral economics, though closely related. From game theory, it differs in premise: game theory assumes rational actors. Bounded rationality begins where this premise is no longer tenable.

The practical consequence is not resignation but design: acknowledging the limits of rationality enables creating conditions under which boundedly rational decision-makers arrive at good outcomes.
