What are mental models?

A mental model is like a simple map in your head that helps you understand how things work.

Imagine you’re playing with building blocks. You have red blocks and blue blocks. If you stack two red blocks, they make a taller tower than one red block. Your brain notices this and creates a little rule: more blocks = taller tower. That rule is a mental model, it’s how your brain makes sense of the world.

Think of mental models like recipes you use every day. When you want to make a sandwich, you probably know that you need bread and something to put inside. You might even have a favorite way to arrange them. That's your mental model for making sandwiches, it helps you make one without thinking too hard.

Mental models are like little helpers in your brain. When you see a cloud getting bigger, your brain might think rain is coming, that’s your mental model for weather! It helps you get ready with an umbrella or stay dry under a tree.

So mental models are just simple rules your brain makes to help you understand and predict the world around you, like knowing that stacking more blocks will make a taller tower.
