Ugly people are Criminals, more often!?

I stubled upon this very interesting article in the washington post called The Ugly face of Crime.. The shocking news:

Not only are physically unattractive teenagers likely to be stay-at-homes on prom night, they're also more likely to grow up to be criminals, say two economists who tracked the life course of young people from high school through early adulthood.

I don't think we can take this study at face value since "attractive looks" are a result of both genetic makeup AND self-cair (clothes, hair style, clothes, etc.). Another way of reading the result of this study is:

People who have criminal-tendencies are less likely to take care of their looks (being less attractive, care less about what others think).

And, unfortunately, I can see how some people can get into a vicious circle as a result:

People who are born somewhat unattractive can grow hateful-tendencies to the world (because how it reacts to them), and thus care less about their looks and become even less attractive, .... and then turn into criminals.

This is very ugly thing to say... right?

Finally: I want to point out that the criminal-tendencies differences mentioned in the survey are SMALL. This means that there are so many other causes that drive people into crime that are much stronger than looks. And, these are statistical studies. It doesn't mean it'll happen to every person.

My own theory is that beauty is all in our minds (in the eye of the beholder). Thus, I can see any person as very nice is I connect his person with nice-deeds. And vica-versa. In a way, a nice person's look is the definition of beauty.
