One post insisted the 80/20 rule is a law. Find the 20% that gives 80% of results and double down.

Skeptics replied that the numbers rarely land at exactly 80 and 20. They're both partly right.

What it actually says

The Pareto principle is an observation that results are often uneven: a small share of causes drives a large share of effects. The split varies. It's a rule of thumb.

Where it's misused

Treating 80/20 as an exact ratio.
Skipping the 'boring 80%' that keeps things working.
Assuming the high-value 20% is obvious.

Use it well

Do more of those, on purpose.
Simplify or batch the low-value tasks so they still get done.
See do to-do lists work.
