Target Audience

Ideal Reader

  • Investors who want better judgment under uncertainty (not stock tips)
  • Anyone building a repeatable decision process: checklists, pre-mortems, and bias controls
  • Business builders and allocators thinking about incentives, moats, and capital allocation
  • People who enjoy dense, high-signal speeches and aphorisms

May Not Suit

  • Readers who want a step-by-step valuation textbook (DCF/accounting heavy)
  • Short-term traders looking for tactics, setups, or timing rules
  • People who dislike philosophy/mental models and prefer purely quantitative playbooks

Key Learnings

  • 1Your edge is a better decision process, not better predictions
  • 2Build a latticework of mental models across disciplines; single-model thinking breaks
  • 3Invert problems: avoid failure modes first, then optimize
  • 4Incentives are a master lever; misaligned incentives create predictable disasters
  • 5Biases do not act alone; combinations can create lollapalooza outcomes (extremes)
  • 6Prefer simple, robust reasoning to fragile precision
  • 7Opportunity cost is real: every yes is a no to something better
  • 8Spend your time on high-leverage decisions; avoid constant low-quality activity
  • 9Patience + quality + discipline beats cleverness applied inconsistently
  • 10Avoid leverage and fragility; survival is compounding prerequisite

The Great Financial Scandal of 2003

Takeaway

Incentives + weak governance + complexity can produce systemic bad behavior and predictable blowups.

portfolio

Investment practices of charitable foundations

Takeaway

Bad process and committee incentives can destroy long-term outcomes even with good intentions.

market

Academic economics vs real-world decision-making

Takeaway

Models are tools; when they ignore incentives, psychology, and second-order effects, they mislead.

Notable Quotes

Spend each day trying to be a little wiser than you were when you woke up.

Compounding applies to learning and judgment, not just money.

Invert, always invert.

Avoid failure modes before optimizing.

Without numerical fluency you are like a one-legged man in an ass-kicking contest.

If you cannot reason with numbers, you will be fooled.

Mental Models

  • Latticework of mental models (multi-discipline thinking)
  • Inversion (solve by avoiding what causes failure)
  • Incentives (follow the payoff function)
  • Second-order effects (what happens after what happens)
  • Base rates (start with reference classes before stories)
  • Circle of competence (know what you truly understand)
  • Opportunity cost (best alternative matters)
  • Compounding (small advantages + time)
  • Margin of safety (buffer against error and bad luck)
  • Checklist discipline (reduce avoidable stupidity)
  • Probabilistic thinking (ranges, not point estimates)
  • Lollapalooza effects (multiple forces reinforcing to extremes)

Key Terms

No glossary terms documented for this book.

Limitations & Caveats

Keep in mind

  • Not a stock-picking cookbook; you must translate principles into your own process
  • Not a modern markets/ETF/tax implementation guide
  • Easy to collect mental models without changing behavior
  • Can be misused to justify overconfidence (I have many models so I must be right)

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
