14 mental models worth adding to your toolkit:
A problem solved with the wrong framework stays a problem.
The right one makes the answer obvious.
➤ For simplifying complexity:
↳ Occam's Razor: the simplest explanation that fits the facts is most likely correct.
↳ First Principles: strip the problem to its fundamentals and reason up from there.
➤ For focusing your effort:
↳ 80/20 Rule: 20% of your inputs drive 80% of your outputs. Find that 20%.
↳ Parkinson's Law: work expands to fill the time you give it. Give it less.
➤ For high-stakes decisions:
↳ Inversion: instead of asking how to succeed, ask how to avoid failing.
↳ Second-Order Thinking: consider the downstream effects of every choice.
↳ Regret Minimization: imagine yourself at 90 looking back. Choose what you won't regret.
➤ For escaping mental traps:
↳ Sunk Cost Fallacy: past costs you can't recover shouldn't drive future choices.
↳ Hofstadter's Law: things always take longer than expected, even when you plan for it.
↳ The Spotlight Effect: people are far less focused on you than you think.
➤ For understanding people:
↳ Hanlon's Razor: before assuming malice, check for incompetence first.
↳ Murphy's Law: anything that can go wrong will. Plan for it before it does.
➤ For thinking and learning:
↳ Feynman Technique: if you can't explain it simply, you don't truly understand it.
↳ Hitchens' Razor: what can be asserted without evidence can be dismissed without evidence.
The difference between a good decision and a great one is usually the framework you used. Now you have 14.
