Speaking in evolutionary terms, confidence suggests that you are a good potential mate, or a superior competitor. Even if someone is short, poorly dressed and unappealing – if they are supremely confidence then it will seem as though they know something you don’t. The assumption is that they must have a reason to be that confident.And thus we instantly assume that this person is somehow our superior: that we should try to impress them, or try to be more like them.
That’s why we gravitate toward confident people, want to date them and want to be liked by them. A lot of people don’t realize the importance of confidence and they think it is enough to be nice. They assume that by acting nice, they will get people to like them and they can that way overcome their looks, their stature, or their status.
