first-principles

First Principles Technique

**Origin**: Aristotelian reasoning, popularized in innovation context by Elon Musk and others. Distinct from reasoning by analogy.

**Interaction type**: Generate — AI decomposes to fundamentals, then rebuilds novel solutions.

How It Works

1. **Identify the conventional approach** — how is this problem normally solved? 2. **List all assumptions** embedded in the conventional approach 3. **Challenge each assumption** — is it a physical law, or just a convention? 4. **Decompose to fundamentals** — what are the irreducible truths? 5. **Rebuild from fundamentals** — without the conventional assumptions, what new solutions emerge?

Decomposition Framework

Layer 1: Surface (What people do)

• Current behaviors, products, services
• "Everyone does it this way because..."

Layer 2: Convention (Why they do it)

• Industry norms, best practices, legacy reasons
• "We've always done it this way because..."

Layer 3: Constraints (Real vs. assumed)

• Physical laws, regulations, actual technical limits
• vs. "We assumed this was a constraint but it's actually a choice"

Layer 4: Fundamentals (Irreducible truths)

• What must be true regardless of implementation?
• What does the user actually need (not what they're used to)?
• What are the physics/economics that can't be changed?

Example

**Topic**: Improving conference networking

• **Conventional**: Name badges, cocktail hours, speed networking sessions
• **Assumption challenged**: "People need to be in the same room to network"
• **Assumption challenged**: "Networking means meeting new people"
• **Fundamental**: People need to find others with complementary interests/needs
• **Rebuilt**: A system that matches attendees by complementary gaps (what you need + what you offer) and creates micro-contexts for connection, regardless of physical proximity

AI Application Notes

When using first-principles internally:

1. Don't just list the fundamentals — actually strip away conventions and rebuild 2. The power is in identifying which "constraints" are actually conventions 3. Best used when ideas feel incremental — first-principles thinking produces category-shifting ideas 4. Present the rebuilt ideas as concrete concepts, not philosophical observations 5. Can combine with other techniques: first-principles decomposition → analogy transfer → SCAMPER refinement
