I agree that people probably stay within the same class of sociability throughout their entire life-- but I think that as one gets older the disparity between the loners and socialites gets much closer. With that being said, I still don't think you can take any kind of result from this age-group seriously. Even if we assume that these people will stay within the same sociability class, your twenties might just be a busy time in your life where hard work at your career and education make you happier. That might not hold true when you're 60.
