The 80/20 Principle

Three of the ideas you’ll keep

The Clif summary of The 80/20 Principle pulls out 7 insights. Here are the first three.

1. The **80/20 Principle** asserts a predictable imbalance: about 80% of outputs, rewards, and results come from about 20% of inputs, effort, and causes, the numbers are illustrative, not exact, and the split can be 90/10 or 99/1.
2. Koch distinguishes **80/20 Analysis** (measuring the data to locate the vital few) from **80/20 Thinking** (an intuitive, non-quantified habit of asking which small share of anything is generating most of the value).
3. Most effort is **low-yield background noise**; a **vital few** inputs are hugely productive. The trap is treating all inputs as equal, so we spread ourselves thin instead of concentrating on the productive minority.

The other 4 — and the full 11-minute summary — are in the app.
