First Principles Thinking
First principles thinking is the priority check that strips a choice to what must be true.
Use it after the problem is named and before the plan is defended.
The Move
- Name the decision.
- Delete inherited assumptions.
- List the truths that survive.
- Rebuild the option from those truths.
- Test the option against reality.
If the truths do not hold, the priority does not deserve attention yet.
What Counts
| Layer | Question | Where it points |
|---|---|---|
| Problem | What gap is real? | Problems |
| Principle | What must be true? | Science principles |
| Agency | Who can act on this truth? | Agency |
| Business | Where does truth meet value? | Business principles |
| Standard | What proof will hold? | Standards |
Proof Loop
Principles are not slogans. They earn weight when they survive use.
Run the loop:
- Claim: what you believe must be true.
- Test: the cheapest contact with reality.
- Signal: the evidence that changes the decision.
- Update: the tighter principle you can reuse.
The principle ledger improves only when evidence changes the next action.
Context
- Priorities — the choice spine.
- Perspective — the lens check after principles.
- Predictions — the forward check before commitment.
- Scoreboard — proof that the principle changed reality.
- Systems Thinking — the loop view.
Questions
- Which assumption are you treating as a fact?
- What would prove the principle wrong?
- What smaller test would expose the truth faster?
