epistemology Adult

Grasp basic statistics

The world argues in numbers — learn to hear when they lie.

What to learn

Understand basic statistics — averages, probability, correlation vs. causation, how numbers mislead — enough to read a claim honestly.

The problem it solves

Statistical illiteracy makes people easy to fool with charts, percentages, and “studies show” — most of modern persuasion.

How to teach it

Teach a child

Take apart a real statistic in the news — what it does and doesn’t show, correlation vs. cause, the missing base rate. Make “compared to what?” a reflex.

Teach yourself

Learn the core ideas — averages and spread, probability, correlation isn’t causation, base rates, how graphs deceive — enough to ask “compared to what, and how do they know?” of any number thrown at you. Most misleading claims wear a statistic; seeing through it is a superpower.

Tactics that teach it

The Worked Example adult habit

Study one done-well example closely before you attempt it.

Before trying a new skill, find one instance of it done well and take it apart — the contract, the essay, the negotiation, the finished project. A single worked example shows you the shape of “good” faster than any amount of abstract advice.

Done when

Reads statistical claims critically — spotting misleading numbers, correlation-as-causation, and missing context.

In the framework

Statistics is where “reality is independent of belief” meets a world that argues in numbers. Grasping it is how you hold quantitative claims to evidence instead of being dazzled by them.
