How does confirmation bias influence our beliefs?

Confirmation bias is when we look for things that match what we already believe, and ignore or forget things that don't.

Imagine you have a favorite toy, let's say it's a red ball. You think the red ball is the best toy ever. Now, every time you play with another toy, like a blue car, you might think, "Hmm, not as fun as my red ball." But if someone shows you a green robot that’s super cool, you might say, "Oh, I didn't notice it before!" That's confirmation bias, you're seeing what agrees with your belief (the red ball is best), and missing or downplaying the things that don’t.

Your brain works like a detective. When you have a favorite toy, your brain says, "I want to prove how awesome this toy is!" So it pays more attention to clues that support your idea, like when your red ball rolls really far, and ignores clues that might say otherwise, like when the green robot does tricks you can't do.

It's like having a friend who only tells you the good things about your favorite snack. You might not realize there are other tasty snacks out there!
