Ask whether the question is valid

Many bad decisions come from accepting the wrong question. First-principles thinking starts with boundaries and assumptions.

  • Separate facts, opinions, positions, and narratives
  • Find hidden assumptions
  • Rewrite the problem definition

Reason from mechanisms

Stable judgment comes from understanding mechanisms: incentives, constraints, feedback, and path dependence.

  • Look at structure instead of slogans
  • Look at constraints instead of wishes
  • Look at feedback instead of one result

Train judgment in daily cases

The method becomes valuable when problem definition, evidence quality, and action verification become habits.

  • Decompose real cases
  • Record judgment grounds
  • Calibrate models with outcomes
