Herbert Simon

Polymath of bounded rationality whose concepts recur as diagnostic tools across the vault. "Satisficing" and heuristic search are the same move — good enough under limited computation — and the vault uses them to reframe the perceptron "sterility" conjecture and the combinatorial-explosion critiques of early AI. He is also the vault's stock example of AI overpromising (the 1960 prediction that machines would match any human work within twenty years) and the source of the "expert intuition = domain-bound pattern recognition" line that connects to Kahneman–Klein on high- vs low-validity environments.

Log

• 2026-08-01: Gigerenzer's camp explicitly frames ecological rationality as "directly building on Simon's program of bounded rationality" (Nordli, Todd & Gigerenzer 2017) — Simon is the shared ancestor both the ecological and the Bayesian-rational-analysis camps measure their "bounded/good-enough" language against (claim-gigerenzer-camp-defines-ecological-rationality-as-not-optimization).
• 2026-08-15: Lighthill's 1973 report singled out the "general problem-solving programs" paradigm Simon co-founded with Newell as persistently disappointing — yet its 38-name acknowledgment list, read directly, includes neither Simon nor Newell; the report critiques their research line without consulting either founder (claim-lighthill-1973-report-consulted-minsky-mccarthy-not-newell-simon).
• 2026-08-22: McCarthy's own 1973 Lighthill review names "the GPS formalism" directly as an example of general schemes whose "inventors" made "published predictions" that were "mistaken" — a contemporary insider naming the Newell–Simon line specifically, the direct-naming counterpart to Simon's own falsified 1960 forecast (claim-mccarthy-1973-named-gps-formalism-source-of-mistaken-predictions).
• 2026-08-29: The "expert intuition = recognition" line has at least two distinct primary homes that secondary sources conflate — the 1986 McKinsey Quarterly passage (undigitized, unlocated online) and a 1992 Psychological Science line ("intuition is nothing more and nothing less than recognition") — a source-disambiguation the vault now tracks (claim-two-distinct-simon-intuition-quotes-1986-mckinsey-and-1992-psych-science-conflated, claim-simon-intuition-quote-traces-to-undigitized-1986-mckinsey-article).
• 2026-09-05: The 1992 Psychological Science line is now Tier-1 anchored — "Intuition is nothing more and nothing less than recognition" was read verbatim from Carnegie Mellon's own archival copy of "What Is an 'Explanation' of Behavior?" (p. 154), the first direct primary read of it in the vault (claim-simon-1992-intuition-is-recognition-quote-confirmed-verbatim-primary). The 1986 McKinsey leg stays undigitized.
• 2026-09-08 (cross-model audit, claude-opus-5): the page in the line above is corrected — the quote is on p. 155, in the "Expert Behavior" subsection, not p. 154. The quote itself is re-confirmed verbatim against the same CMU archival scan; only the locator was wrong.
