Poor Charlie’s Almanack

By Charlie Munger (compiled by Peter D. Kaufman) · 2005

A collection of Munger’s talks on investing, decision-making, psychology and the use of multidisciplinary mental models.

Poor Charlie’s Almanack brings together speeches, lectures and public commentary by Charlie Munger, the long-serving vice-chairman of Berkshire Hathaway. Edited by Peter D. Kaufman, the collection examines Munger’s approach to investing, business and practical judgement. Rather than treating financial analysis as a self-contained discipline, Munger argues that better decisions come from drawing on useful ideas across economics, mathematics, psychology, history and the sciences.

A central theme is the use of “mental models”: conceptual tools that help people understand complex problems from several perspectives. Munger also considers common errors in human reasoning, including psychological biases that can distort judgement when they operate together. His discussions connect these ideas with investment selection, management and everyday decision-making.

The book also addresses learning, ethics and personal conduct. Its title refers to Benjamin Franklin’s Poor Richard’s Almanack, reflecting Munger’s interest in practical knowledge, self-education and principles that can be applied across different areas of life.
