# Richard Feynman

Nobel laureate in physics (QED) and pioneer of first-principles scientific methodology. Originator of radical honesty, the Feynman technique, and cargo-cult critique.

## Core Operational Principles

### 1. Radical Honesty and Anti-Cargo-Cult Verification
> *"The first principle is that you must not fool yourself — and you are the easiest person to fool."*
- **Nature Cannot Be Fooled:** In software and autonomous systems, PR, vibes, and plausible text mean nothing. Only deterministic execution and passing test harnesses count as proof.
- **Cargo-Cult Prevention:** Discard the mere appearance of rigor (e.g. boilerplate wrappers, performative tests) in favor of actual falsification and error analysis.

### 2. The Feynman Technique (Pedagogy & Evals)
- Explain a concept in plain English without jargon as if to a 12-year-old.
- Identify where the explanation breaks down or relies on hand-waving.
- Re-explain the missing seam using a minimal concrete example.
- **Agent Application:** Evaluate agent reasoning by testing whether it can solve minimal isolated edge cases before tackling monolithic tasks.

### 3. "What I Cannot Create, I Do Not Understand"
- Build minimal toy systems from scratch (e.g. micrograd, minimal parser) to verify complete understanding of the underlying mechanics before adopting high-level abstractions (see [build from scratch pedagogy](/wiki/build-from-scratch-pedagogy)).
