AI Overview
Herbert Simon, a Nobel laureate in economics, and Richard Feynman, a Nobel-winning physicist, approached problem identification and solving from different, yet complementary, angles. Simon studied the cognitive processes of problem-solving (largely from the perspective of how humans and computers function), while Feynman was a practitioner known for his unique techniques in identifying and solving complex physics problems.
Simon’s Perspective on Problem-Solving
- Bounded Rationality: Simon argued that human decision-making is limited by the tractability of the problem, information availability, and time constraints, leading people to "satisfice" (choose an acceptable solution) rather than optimize.
- Problem Space Theory: Together with Allen Newell, Simon proposed that people solve problems by navigating a "problem space" consisting of an initial state, a goal state, and potential steps (operators) in between.
- Three Phase Model: Simon defined the problem-solving process in three phases:
- Intelligence: Finding the problem.
- Design: Formulating and analyzing alternatives.
- Choice: Selecting an alternative.
- Heuristics: When dealing with novel problems, Simon proposed that people use cognitive short-cuts or heuristics to navigate large possibilities.
Feynman’s Problem-Solving Techniques
- The 12 Problems Technique: Feynman was known for keeping about 12 of his favorite, often challenging, problems in his working memory. He would apply any new knowledge, mathematical tool, or approach he encountered in other fields (like biology or chemistry) to each of these 12 problems to see if it yielded a new solution.
- Rethinking the Approach: Feynman believed that fundamental laws could often be described in multiple, seemingly non-identical ways. By constantly looking for alternative, simple ways to explain a phenomenon, he found new paths to solutions.
- "Hard" Problem Identification: Feynman emphasized the importance of maintaining a "feel" for the solution, aiming to understand the result before fully solving the equations.
Comparison and Synthesis
- Difference in Focus: Simon focused on how humans, in general, navigate decision-making under constraints, while Feynman represented an expert, almost superhuman, approach to solving extremely complex physics problems.
- Integration: Feynman's technique of holding multiple problems in mind and applying cross-domain solutions is an example of what Simon might categorize as an effective, highly developed, heuristic-driven "search" through a "problem space".
- "A Wealth of Information": Simon's famous insight that "a wealth of information creates a poverty of attention" echoes Feynman's need to carefully select and hold only a few important problems (12) in his focus.
