What does the science say about people who slam doors? You know those people who just throw them shut for some reason. It doesn't seem like they're angry, they just don't seem to understand how doors work. I know a guy who does this every time, any time he goes outside it's just BANG, and you can even feel the walls shake from it. Same when he comes from the bathroom, he just violently pushes the door shut seemingly to produce as much noise as possible. And considering how widespread doors are in our everyday life, it seems weird how widespread this is. Is this correlated to IQ somehow
