Poor Charlie's Almanack
by Charlie Munger (ed. Peter D. Kaufman) · 2005
Munger's mental models and the psychology of human misjudgment, in one strange, wonderful book.
Worth reading? The best single-volume education in multidisciplinary thinking and the psychology of misjudgment — strange, repetitive, and worth more than most MBA programs. If you want to invest better, it'll help; if you want to think better across fields, it's the real prize. Skip it if you want a linear how-to; these are speeches, talks, and tangents.

The Verdict
Munger’s talk on the 25 psychological tendencies that cause misjudgment is worth the whole volume, and the “latticework of mental models” idea launched a thousand blogs. The Stripe Press edition trimmed it well. Not really an investing book. A thinking book that happens to be written by an investor.

Book Summary
Munger's core move is the latticework of mental models: borrow the big ideas from physics, biology, psychology, and economics, then look at every problem through all of them at once. A one-trick expert is blind to his own blind spots. The companion is the psychology of human misjudgment — the inventory of biases (reciprocity, envy, social proof, incentive-caused bias) that wreck decisions. His favorite tool is inversion: figure out how to fail, then avoid that, and you'll likely succeed.
