Why Do Economists Always Get Their Forecasts Wrong?

Economists are like weather forecasters but with more math. They try to predict things like unemployment or inflation using big books of numbers called models.

Sometimes their predictions are way off. Why? Because the world changes in ways they did not expect!

Imagine you bring an umbrella because the app says there is a 90% chance of rain. But then it stays sunny and dry. That is called a forecast error. In economics, this happens all the time.

Economists look at the past to guess the future. They assume that things like how people spend money will stay similar to before. But what if everyone suddenly starts saving more because they are worried? Or what if a new technology changes how we work?

These surprises make the old models wrong. It is not that economists are bad at math. It is that the future is tricky!

Economists keep learning from their mistakes. They update their models with new data, just like you update your map when you find a closed road.
