Seeking Wisdom: From Darwin to Munger
Builds out Munger's latticework idea from primary sources.
Summary
Bevelin assembles a structured treatment of human misjudgment and of thinking tools, built largely from Munger, Buffett, Darwin and Feynman, with heavy quotation throughout. The book has four parts: what influences our thinking, the psychology of misjudgment, the physics and mathematics of misjudgment, and guidelines for better thinking.
The psychology section expands Munger's list of misjudgment causes into a longer catalogue with supporting research and examples, covering bias from incentives, self-interest, association, liking, consistency, deprival, envy, contrast, authority, social proof and stress. The physics and mathematics section covers systems thinking, scale effects, the difference between correlation and causation, base rates, regression to the mean, compound interest arithmetic and probability errors.
The final section is the practical one. Bevelin gives guidelines including inversion, working out the base rate before assessing a specific case, using checklists, defining the circle of competence, simplifying by avoiding problems rather than solving them, and thinking about second-order consequences by asking what happens next.
The book is essentially a well-organised compilation rather than an original work, and Bevelin says so. Readers who have read Munger's Psychology of Human Misjudgment and Kahneman will find much of it familiar. The quotation density makes it read as a commonplace book, which suits reference use better than sequential reading. Some of the psychology citations date from before the replication crisis and should be checked. Its value is the organisation, which is better than the sources it draws on.
Key takeaways 8
- Human misjudgment follows a limited number of recurring causes, and a person can learn them as a list and check against it.
- Incentives explain more behaviour than any other single factor, so the first question about any decision should be who benefits.
- Inverting a problem, by asking what would produce failure and then avoiding it, is more reliable than pursuing success directly.
- Base rates should be established before any specific case is assessed, because case detail crowds out statistical information.
- Avoiding difficult problems produces better results than solving them, because the returns to avoiding error exceed the returns to brilliance.
- Second-order consequences matter more than first-order ones and are systematically ignored because they require the additional question of what happens next.
- Checklists compensate for the fact that knowing about an error does not prevent committing it.
- A person should stay inside a clearly defined circle of competence and treat the boundary as more important than the size of the circle.
Who should read it
Investors building a personal checklist of recurring errors, who want Munger's framework organised and expanded with sources.
About Peter Bevelin
Swedish investor and author who assembles the psychology, physics and biology behind Charlie Munger's approach to thinking.
Seeking Wisdom collects the misjudgement patterns, cross-disciplinary principles and checklists underlying Munger's method, sourced back to Darwin, Feynman, Munger and Buffett with citations throughout. The Sherlock Holmes volume drills the same procedure as observation and inference practice.
