Most Helpful Guy
Average is relative.
Imagine all the guys looked like a variation of Brad Pitt, George Clooney, Richard Gere, Alec Baldwin, etc; and all the women looked like a variation on Halle Berry, Maria Menounos, Megan Fox, Eva Mendes, etc.
Now; perhaps if it were a more level playing field in looks, we might become a society that bases decisions more on personality and behavior. But perhaps not. We would probably still rate people on looks and appearance; the standards might change a little, but otherwise, we'd still have "average" people, even if those people looked by our current standards, spectacular.
A lot of people think that a friend's child is either my little sister, or, on occasion, my daughter. Others think I look nothing like her (though admittedly, most people do). I don't see it, except for perhaps the hair color. There are different opinions that shape how we perceive someone, even physically. It's probably because I play with the kid and tease, and act like a big brother, and take the hair color, and boom, we must be related. So people perceive us to look more like each other than we actually do.
My point is that sometimes there are different variables that make people perceive that "average" is.
My "average," will not be your "average." You might like Pamela Lee types, and I may not. I may think the smart chicks make them hotter, and you might not.
So many average people... that's hard to define. You might live in the richest area of California, (someplace that seems to be all about outward appearance.) and ask the same question.
