Calibrating how much care a decision deserves — avoiding over-deliberation on reversible choices and under-deliberation on irreversible ones
Core Concept
Bezos categorizes decisions as two-way doors (reversible — you can walk back through if you don't like what you see) or one-way doors (irreversible — once you pass through, you can't return). Most decisions are two-way doors, but people treat them like one-way doors, causing excessive slowness and cost.
✓ When to use this
Classify before deciding: is this a two-way door (reversible) or one-way door (irreversible)? Move fast on reversible ones and learn by doing; slow down on irreversible ones with pre-mortem and margin of safety.
✗ When not to use this
Marking everything one-way breeds over-caution and paralysis — many decisions are more reversible than they feel. Conversely, mislabeling irreversible calls (contracts, public commitments) as two-way is expensive.
Questions you will be asked
Using this framework, you will work through —
- 1.What is this decision?
- 2.If you execute this decision and regret it, can you return to the status quo? At what cost?
- 3.Is this a one-way or two-way door? What's your reasoning?
- …and 3 more
