Every bad decision you’ve ever made
started with an assumption you never questioned.
First Principles strips your reasoning back to what’s actually true — then rebuilds from there.
You inherited most of your reasoning. From school. From your industry. From “how it’s always been done.” First Principles identifies every assumption in your thinking and tests whether it holds. Most don’t.
The people who get this right make decisions everyone else catches up to later.
The Six Stages
- 1Identifying the actual problem (not the presenting symptom)
- 2Stripping inherited assumptions from a position
- 3Locating the verifiable evidence beneath a claim
- 4Constructing a position from first-verified premises
- 5Testing the position against the best available counter-evidence
- 6Committing to an updated conclusion without identity attachment
The Training Structure
Domain Scenarios
Every training session is built around real-domain scenarios — clinical, legal, engineering, financial — where first-principles reasoning produces materially better outcomes than pattern-matched assumptions.
Assumption Stripping Exercises
Structured exercises identify the inherited assumptions embedded in a decision. Learners locate them, test them against evidence, and replace them with verified premises.
Performance Measurement
Reasoning quality is measured at each stage of the framework, not just at the final answer. Progress is visible, specific, and tied to the stage where it occurred.
Who Uses First Principles
Anyone who wants to think better
People who want to improve their thinking, people entering careers where clear reasoning is essential, and people who care about reaching what is actually true — not just what sounds right.
Engineers and product teams
Teams that need to solve novel problems without defaulting to inherited solutions.
Clinical and legal professionals
Professions where assumption-based errors produce irreversible consequences.
Executives and strategic decision-makers
Leaders who need to separate market assumption from market reality before committing resources.
