Good Looking

What is it about good looking people that makes others gravitate towards them? Or makes people give them special favors or thinks their opinions are "all that" - like they occupy a higher plane of being? Is it just human nature that people want to be around or look at pleasant things? I mean, I think most people know deep down that just because you're good looking, it doesn't mean you are smarter or more apt than others. I've also seen situations where people try to impress good looking people, as in, if this "looker" thinks I'm special, then I really must be worthy. ... I just find it a curious phenomenon.
