Observer-expectancy effect

The observer-expectancy effect is a thing that happens when you're expecting something to happen, and then it ends up happening because of it. Think of it like a game of make-believe. If you think that something is going to happen, then chances are it will. It's like if you think that your best friend is going to give you a hug, then they will give you a hug. It's all about how you think and how that affects the outcome!
