Reversible and irreversible

Reversible and irreversible: How much deliberation a decision deserves depends mostly on what undoing it would cost. Decide the cheap-to-reverse ones today.

Free — no account needed to read

How much deliberation a decision deserves depends mostly on what undoing it would cost.

Try it now

List five decisions on your plate. For each, write what it would cost to reverse — in money, time and relationships.

What to do with the answer

Decide the cheap-to-reverse ones today. Give the slow pass only to the expensive ones.

Reversal cost is not importance. Small irreversible decisions exist, and some cheap ones compound.

The module it belongs to

  • Decision Thinking — Make better decisions under uncertainty

The book behind it

  • Decisive — Its big ideas, in our own words.
