ELI5: Explain Like I'm 5

Cognitive bias

Cognitive bias is when our brain comes up with beliefs or opinions in our mind that may not be true but we believe them anyway. It might be things like thinking everyone likes you, or that your idea is the best, even if it isn't true. Cognitive bias means that our thinking is not always accurate. It can cause us to think about things in the wrong way, and make decisions that we may later regret.
