Why Do People Believe in ‘Luck’ and How Does It Affect Decisions?

People believe in luck because it feels like something invisible helps them win or lose when they play games or try new things.

Imagine you're playing a game with your friend where you both pick a number from 1 to 10. If you pick the same number, you win a piece of candy. Sometimes you win right away, that feels like good luck. Other times, you keep picking and losing, that feels like bad luck.

But here's the fun part: sometimes it looks like luck is helping you or hurting you when it’s really just chance working its way through the game.

When someone wins a big prize on a toy machine at the store, they might say it was luck. But that person probably tried many times before, some of those tries were just regular attempts, not special or magical.

People who think they're lucky might try again because they believe good luck will come back. Others might stop trying if they feel bad luck has stuck with them. It's like believing a cookie monster is watching you, it can change how you act in the game!
