🎒 The lesson

<aside> 🌍

You already know a great deal about the world. Today we find out how much of it is true.

</aside>

Last lesson ended with an idea: a map is not the world itself, only a picture of it, shaped by whoever drew it. Today we look at the pictures of the world you carry in your own head, which countries are rich, which are poor, who leads and who lags, and we test them against real data.

✅ How you work today

You will not type on this page. Open a Google Doc, title it The world we think we know, and keep all your notes and answers there.

Today's question: How well do we really know the world, and why are we so often wrong about it?

</aside>

🌍 1. A quick test

Before anyone says what today is really about, a test. You know a lot about the world already, so let's see how good that knowledge is.

<aside> 🗳️

As a class: Your teacher will show you six countries and one measure, such as how long people live. Predict the order, highest to lowest. Lock in your answer before the reveal, then watch what the real data does to it.

In your Google Doc, one sentence: we kept getting these wrong in the same direction. Why do you think that happened? You do not need to be right, just commit to a guess.

🔎 2. Crack the rule

Now a game. Your teacher is using a secret rule that sorts countries into two groups: ones that fit the rule, and ones that break it.

<aside> 🎯

As a class: Call out any country. You will be told whether it fits the rule or breaks it, and it will drop into one of two columns. Your job is to work out the secret rule. Keep testing countries until you are confident, then say your rule out loud before the reveal.

In your Google Doc: Which countries did you choose to test, and what rule did you think it was? Were you confident?

🧠 3. So what just happened?

Look back at the countries the class chose to test. Most classes pick countries they expect to fit the rule. They are hunting for a "yes". Almost nobody tries a country they expect to break it, so the "breaks" column stays nearly empty, confidence grows, and the real rule stays hidden far longer than it should.

That habit has a name.
