Herbert A. Simon (1916-2001) – Nobel Prize in Economics 1978
Summary: Bounded rationality challenges the classical economic assumption of perfectly rational decision-making. Proposed by Herbert Simon, it acknowledges the cognitive limits of humans when processing complex information, arguing that decision-makers settle for "good enough" solutions rather than optimal ones.

1. The Origins of Bounded Rationality
1.1 Historical Context
Herbert Alexander Simon (June 15, 1916 – February 9, 2001) was an American political scientist whose work influenced computer science, economics, and cognitive psychology. He received the Nobel Memorial Prize in Economic Sciences in 1978 and the Turing Award in 1975. Simon coined the phrase “bounded rationality” in 1957 as a counterweight to the then-dominant model of “classical economic man”, which presumed that actors making decisions are perfectly and optimally rational. Simon insisted that cognition is “bounded” by internal limits, not just external ones, because the capacity of the human mind for formulating and solving complex problems rationally is limited.

1.2 The Challenge to Perfect Rationality
Simon contrasted his approach with neoclassical economics, which assumed rational, self-interested individuals maximized satisfaction given their constraints. Simon proposed a different assumption: humans are bounded by their own cognitive limits due to an inability to obtain or process all the information needed to make fully rational decisions. As he stated, “decision makers can satisfice either by finding optimum solutions for a simplified world, or by finding satisfactory solutions for a more realistic world”.

2. Core Components of Simon's Theory
2.1 Definition of Bounded Rationality
Bounded rationality is an alternative conception of rationality that models the cognitive processes of decision-makers more realistically. The concept describes a relationship between a person’s mental abilities and the complexity of the problem he or she faces. Because humans are severely limited in their cognitive and computational abilities, knowledge is always incomplete, and time is fixed.
This is not to say that people are irrational. Rather, acting rationally — which for Simon meant following rule-bound processes — includes countenancing the finite amount of information minds can bring to bear on their decisions.

2.2 Satisficing: The "Good Enough" Principle
For Simon, satisficing is a strategy for decision-making in which an individual or firm seeks an option the outcome of which is satisfactory or “good enough” rather than best or optimal. Satisficing stands in contrast to maximizing models dominant in rational choice theory. Simon used satisficing to explain the behavior of decision makers under circumstances in which an optimal solution cannot be determined, often due to computational intractability or lack of information.

3. Real-World Examples
3.1 Everyday Decision-Making Example
Consider purchasing a bottle of whisky as a gift. To make this decision optimally, you would need to look at every bottle available, comparing price, age, prestige, and other factors. Herbert Simon suggested that in all but the most basic settings, we are simply unable to make optimal decisions. Instead, we satisfice — selecting the first alternative that meets our aspiration level.

3.2 Fast and Frugal Heuristics
A non-economic but illuminating example is the gaze heuristic, used by both dogs and people when catching a flying object. To know the exact trajectory of a ball, one would need to solve prohibitively difficult differential equations. Instead, both humans and dogs look at the ball while tilting their head at a particular angle and run, adjusting speed so that this angle stays constant. Such heuristics are “fast” because they do not require massive computational effort and “frugal” because they use as little information as possible.

4. A Legacy Case Study
4.1 Enron: When Bounded Rationality Meets Information Myopia
Company: Enron Corporation (2001)
Decision: Concealing debt through off-balance-sheet partnerships while engaging in risky energy trading.
Data Used: Incomplete and manipulated financial data hidden from investors and regulators.
Outcome: Bankruptcy in December 2001; dissolution of Arthur Andersen; $74 billion market capitalization loss.
Relevance to Bounded Rationality: The Enron scandal demonstrates how “bounded rationality” explains the surprising role of irrationality in decision-making due to unconscious emotions and motivations, combined with a willful ignorance of known information — a failure not of missing information but of willfully ignoring what was known.
Lessons Learned: Bounded rationality can be weaponized when decision-makers choose to ignore warning signs. Structural checks and transparent information flows are essential to counteract this tendency.

FAQ
How is bounded rationality different from irrationality?
Bounded rationality is not irrationality. Bounded rationality refers to making rational decisions within cognitive and environmental limits. Irrationality would mean making decisions that contradict one's own goals despite having the information to do otherwise. Simon insisted that acting rationally — which for him meant following rule-bound processes — includes countenancing the finite amount of information minds can bring to bear on their decisions.
