1. 30 July 2026 · corrected by Emir Baycan

   Corrected an overstated claim about a researcher's independence from earlier work, a quote that does not match the researcher's documented account, and a weakly sourced anecdote presented as settled history, plus a date error.

   What the page claimed

   Article claimed Charlie Munger developed his psychology-of-misjudgment framework independently of and before Daniel Kahneman and Amos Tversky's work, though Munger has repeatedly and explicitly credited their research as foundational to his own. It also included a specific quoted internal monologue attributed to Gary Klein's fire commander research that does not match his documented published account, presented the British colonial India 'cobra effect' anecdote as straightforward documented history when historians have found the underlying account only weakly sourced, and dated the US Forest Service's fire-suppression policy to 'the 1970s' when the policy was formalized in 1935.

   What was corrected

   Corrected the Munger claim to accurately describe his framework as building on, not independently preceding, Kahneman and Tversky's research. Replaced the Klein quote with an accurately hedged paraphrase of his documented findings about expert mental simulation, added appropriate historical hedging to the cobra effect anecdote, and corrected the fire-suppression policy's date to reflect its actual 1930s formalization.

   Why: Verified against Munger's own 'Psychology of Human Misjudgment' speech (which explicitly credits Tversky and Kahneman), Gary Klein's published 'Sources of Power' for the actual documented quotes, historical research on the cobra effect anecdote's sourcing, and US Forest Service history on the 1935 '10 AM Policy.'
