Could you provide a source on that please? Because from the wording of your statement it seems that what you are claiming is completely anecdotal. I remember studying in one of my psychology courses that attractive people are instantly assumed to be smarter and more successful than unattractive people. It even has a name although I can't think of it right now. If I could I would provide a source.
edit: Here is a source, not really great but it's something. http://www.psychologytoday.com/blog/wired-success/201108/why...
edit2: The word I was looking for was halo effect. http://en.wikipedia.org/wiki/Halo_effect http://en.wikipedia.org/wiki/Physical_attractiveness_stereot...
