→Limitations of mental frameworks
For these reasons, effective thinkers typically maintain a diverse set of mental frameworks, update them regularly, and remain willing to revise or replace them when new evidence requires it.

== Model of thinking ==
=== Core models for thinking clearly ===
These are the universal models that improve judgment in any domain.
'''1.''' First Principles Thinking
Break problems down to their fundamental truths and rebuild from the ground up.
'''2.''' Second‑Order Thinking
Look beyond the immediate effect to the downstream consequences.
'''3.''' Inversion
Solve problems by asking the opposite question: “How could this fail?”
'''4.''' Occam’s Razor
Prefer simpler explanations when evidence is equal.
'''5.''' Hanlon’s Razor
Don’t attribute to malice what can be explained by incompetence or incentives.
'''6.''' Probabilistic Thinking
Think in likelihoods, not certainties.
'''7.''' Bayesian Updating
Revise beliefs as new evidence arrives.
=== Models for Decision-Making and Strategy ===
These help you choose well under uncertainty.
'''8.''' Opportunity Cost
Every choice has a hidden cost: the next best alternative.
'''9.''' Comparative Advantage
Specialize where you’re relatively strongest, not absolutely strongest.
'''10.''' Expected Value
Weigh outcomes by probability × payoff.
'''11.''' Marginal Utility
The value of the next unit is not the same as the first.
'''12.''' OODA Loop (Observe–Orient–Decide–Act)
Fast, iterative decision cycles beat slow, perfect ones.
'''13.''' SWOT Analysis
Clarifies strengths, weaknesses, opportunities, threats.
