Ludic fallacy is when someone thinks something works in real life the same way it works in a game. For example, if you are playing a game where you get points for doing something good, like answering a question and getting it right, you might think you'll get something in real life like a reward when you do something good. But that isn't true, because in real life, rewards aren't always given when you do something good. In real life, people and things don't always work the same as they do in a game.
