I've known a few cheerleaders. Interestingly, the few I knew were very intelligent. One of them was an honors student in college who went into marketing, another was an economics major like me who ended up becoming a news reporter last I heard from her. There was another one whom I've lost touch with, but she was also pretty intelligent. I think she was an accounting major. All I remember about her otherwise was that she got lots and lots of tension headaches and was always popping pills for them. I felt bad for her because she really seemed to be suffering.
Then there were a bunch that I met in passing, and some were in clubs and/or professional fraternities with me. They all seemed nice and relatively intelligent. It was only in high school that the cheerleaders were mind-numbingly stupid.
