Herbert A. Simon

Herbert A. Simon

Herbert A. Simon was a pioneering scholar whose work reshaped economics, organizational theory, and artificial intelligence (AI). He challenged classical assumptions about perfectly rational decision-making and helped found the field of AI with early programs that modeled human problem solving.

Key takeaways

• Introduced the theory of bounded rationality and the concept of “satisficing.”
• Showed that real-world decision-making is constrained by limited information, cognitive capacity, and social/institutional factors.
• Co-developed early AI programs that automated theorem proving and simulated human reasoning.
• Received top honors in both economics and computer science for his interdisciplinary contributions.

Bounded rationality and satisficing

Simon argued that individuals and organizations cannot obtain or process all information required for fully optimal decisions. Instead of optimizing, people use available information to reach solutions that are “good enough”—a process he called satisficing (a blend of “satisfy” and “suffice”).

Key elements of his theory:
* Cognitive limits: human memory, attention, and computational capacity constrain decision processes.
* Social and institutional constraints: decisions are shaped by relationships, power dynamics, rules, and organizational structures—not just individual utility maximization.
* Rationality within bounds: even constrained decision-making can be rational when it involves comparing costs, benefits, and risks to arrive at satisfactory outcomes.

Impact:
* Replaced the image of an all-knowing, profit-maximizing “economic man” with cooperative decision-makers operating under real-world constraints.
* Became foundational to behavioral economics and modern administrative and management research.

Contributions to artificial intelligence

In the mid-1950s Simon, together with Allen Newell, began simulating human problem-solving on computers. They produced programs that could prove mathematical theorems and perform symbolic reasoning—early demonstrations of machines that could mimic aspects of human thought. Their work helped establish AI as a legitimate field of scientific inquiry.

Honors and legacy

Simon’s interdisciplinary achievements earned him the highest recognitions in both fields:
* Nobel Memorial Prize in Economic Sciences for his studies of decision-making and organizational behavior.
* A.M. Turing Award for major contributions to computer science and AI.

His ideas continue to influence economics, management, behavioral science, and AI research, especially in areas that model realistic human and organizational decision processes.
