Bezos' Two-Way Door
Updated 2026-09-11
INTRODUCTION
English translation pending.
CORE DEFINITION
Jeff Bezos classified decisions by reversibility. A one-way door cannot be walked back, so it deserves slow, careful deliberation; a two-way door can be re-entered, so it deserves a quick experiment instead of a committee. The model's claim is that most decisions are two-way doors, and that treating them as one-way is how organizations spend their speed on nothing. The complementary practice, sometimes listed as an alternative set, is to build a structured set of alternatives before deciding, so that choice happens among real options rather than between one plan and nothing.
SCAFFOLDING EFFECT
Reduce cognitive load
- Classify the door first: before deliberating, ask whether you can walk back through it. - Speed up the reversible: run cheap experiments on two-way doors and let the result decide. - Slow down the permanent: for one-way doors, spend the effort on irreversibility analysis, not on theater.
Anchor fast decisions
Deliberation cost should scale with consequence, and the cost of being wrong is set by reversibility. A reversible decision wastes resources under heavy process, because the fastest path to the right answer is to try and observe, while an irreversible one cannot be fixed by trying, so its only remedy is care beforehand. Classifying the door aligns effort with stakes, and the reason most organizations are slow is that they apply irreversible-door caution to a queue of mostly reversible choices.
