"Beauty and its neural reward are in the eye of the crowd"

I was reading this article yesterday Beauty and its neural reward are in the eye of the crowd about some research that has been carried out at Harvard University about how peer pressure can affect what we think about people. This article is a summary/thought provoking piece where the experiment is summarised for those of us with the normal attention span of the modern age internet users.

I find it amazing how people's opinion's can be so easily changed by what the main stream opinion is of those around us. We are suppose to have "free thinking", yet when you think about it, how free is our thinking if we can be so easily influenced?
