Reversible vs. irreversible decisions

Most decisions do not deserve the same amount of certainty.

1. 01

   Ask what becomes expensive or impossible to undo—not how emotionally important the choice feels.

2. 02

   For reversible choices, design the exit before the experiment. For irreversible choices, name the evidence threshold before committing.

3. 03

   A deadline without a stopping rule creates urgency, not clarity.
