INTRODUCTION

English translation pending.

CORE DEFINITION

First principles thinking, traced to Aristotle, decomposes a problem to its most basic truths, the propositions that cannot be divided further, and then reasons upward from those foundations to a solution. Its opposite is reasoning by analogy, which copies existing practice forward; the value of the original path is that it bypasses the accumulated assumptions every inherited solution carries, including the ones no one can any longer justify.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- List the assumptions: write down everything the current solution takes for granted. - Push to bedrock: keep asking why until you hit an irreducible fact. - Rebuild: construct the solution from those facts rather than from the inherited form.

Anchor fast decisions

Most innovation is incremental because it starts from an existing solution, which silently imports that solution's assumptions as constraints. Starting from indivisible truths removes the inherited constraints by construction, so the space of candidate solutions widens to include arrangements the analogy path could never reach.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

List every assumption the current approach rests on. 2. Challenge each assumption down to its most basic factual support. 3. Rebuild a solution from those basic facts rather than from the inherited design. 4. Compare the new solution against the analogical one on the merits.
