What is Problem of induction?

The problem of induction is about why we believe things will keep working the way they always have, even though we can’t be 100% sure.

Imagine you’re eating your favorite cereal every morning, and it always tastes the same. You might think, “This cereal will taste good tomorrow too.” But how do you know? Maybe something changed in the kitchen. That’s the problem of induction, trusting that things will stay the same just because they have before.

Why We Use Induction

Every day, we use induction without thinking about it. If your friend gives you a lollipop every time you visit them, and you’ve been visiting for weeks, you might believe they’ll give you one next time too. That’s using past patterns to guess what will happen in the future.

But here's the catch: just because something has happened many times before doesn’t mean it has to happen again. It’s like thinking your favorite toy will always work, until one day, it breaks!

So the problem of induction is about why we believe things will keep working the way they always have, even though we can’t be 100% sure.
