How Charlie Munger Chose What to Read
Munger did not read at random, and he did not read to specialize. His selection rule followed directly from his idea of worldly wisdom: gather the big, durable ideas from the major disciplines and connect them. That meant deliberately reading outside his profession of law and investing — into evolutionary biology, physics, ecology, and behavioral psychology. He favored books that explained how things work at a structural level rather than books that merely reported events. And he reread the ones that mattered: by his own account he read both The Selfish Gene and Guns, Germs, and Steel twice. The list below reflects that filter — every title is there because it added a transferable model to Munger's latticework, not because it was merely interesting.
Psychology: Influence and the Study of Human Misjudgment
Psychology sat at the center of Munger's reading because, in his view, most large mistakes come from predictable cognitive errors. Robert Cialdini's Influence: The Psychology of Persuasion was his single most-recommended book; Farnam Street notes he gave away more copies of it than any other title, and he credited it with filling gaps in his self-taught understanding of cognitive bias. Munger thought so highly of the book that he sent Cialdini a Berkshire Hathaway Class A share as thanks — a detail widely reported in accounts of their relationship. He paired Cialdini's field-tested persuasion research with Daniel Kahneman's Thinking, Fast and Slow, which gave academic structure to the misjudgments Munger had catalogued through decades of observation. Together these books supplied the psychological core of his decision-making framework.
Science: Evolution, Complexity, and Deep Simplicity
Munger believed an investor or lawyer who did not understand basic science was operating with a crippled toolkit. Richard Dawkins's The Selfish Gene reframed evolution around the gene rather than the organism and introduced the idea of the "meme"; Munger read it twice before he felt he had fully absorbed it. He recommended John Gribbin's Deep Simplicity: Bringing Order to Chaos and Complexity, remarking on the title itself — that deep simplicity is "what we're all looking for" — and adding the self-deprecating note that if you cannot understand a hard book, "you can always give it to a more intelligent friend." He called the Gribbins' Ice Age "the best work of science exposition and history that I've read in many years." These were not casual science-for-laypeople picks; they were sources of models about feedback, emergence, and natural selection that Munger applied far outside biology.
Economics, Ecology, and Negotiation
Munger's social-science reading leaned toward books about limits, incentives, and how rational agents actually behave. Garrett Hardin's Living Within Limits: Ecology, Economics, and Population Taboos appears on his recommended list as a clear-eyed treatment of carrying capacity and the hard arithmetic of population and resources — themes Munger returned to when warning against wishful thinking. He pointed business students toward Getting to Yes: Negotiating Agreement Without Giving In by Roger Fisher and William Ury, the classic on principled negotiation that nearly every MBA program assigns. Across this category the unifying idea is that prosperity and conflict both obey underlying rules, and that reading the people who mapped those rules saves you from learning them the expensive way. Munger treated economics less as a standalone subject than as one more set of models to slot into the latticework.
Biography: Studying Self-Made Lives
Munger read biography the way an engineer studies working machines — to see how exceptional people actually operated. Benjamin Franklin was his recurring hero; Farnam Street lists The Autobiography of Benjamin Franklin among Munger's all-time favorites, and Munger admired Franklin as a self-taught generalist whose curiosity ranged across science, business, and public life. He read widely in the biographies of builders and capitalists, drawing pattern recognition about how driven people think under pressure that pure theory could not provide. Munger's own Poor Charlie's Almanack is itself modeled in spirit on Franklin's Poor Richard's Almanack, a debt the title makes explicit. For Munger, the lesson of biography was practical: study the lives of people who compounded knowledge and character over decades, and copy the habits that produced the results.
