Why do humans develop biases and how do they affect decisions?

Humans develop biases because they're like little helpers that make decisions faster, kind of like a shortcut in your brain.

Imagine you have a toy box with 10 toys. If you see one red car and it’s super fun, your brain might think all red cars are fun too. That’s a bias, it helps you decide quickly without checking every single toy.

Biases happen because our brains want to save energy. When we’re deciding something new, our brain uses what it already knows. It's like wearing a favorite pair of socks instead of trying on all the different ones in your drawer.

Sometimes this helps, like when you know your best friend won’t let you down, so you trust them more easily. But other times, it can mess up decisions, like thinking all red cars are fun, even if one turns out to be broken!

When biases affect decisions, they can make us choose things that aren't the best just because they're familiar. It’s like picking your favorite ice cream every time instead of trying something new.

But don’t worry, knowing about biases helps you make smarter choices too!
