To argue that attractiveness doesn't make a difference would just be plain perverse. It's a well known phenomenon sometimes called the Halo Effect. Why else are celebrities used to endorse products that they lack the expertise to judge, or have no prior link to at all? Why are top film stars all attractive, despite the fact that their good looks are no indication of their acting talent? Why are the most popular people in all schools, amongst either sex, usually good looking and athletic? For some reason, we seem to think that beauty can't only be skin deep. In fact, it usually is.
