Keep in mind that in a public, self-reported survey, you're only going to get the answers that people want other people see. Some people will tank it just to mess with it, and whatnot. Of course, if you know this, then you can get a whole other level of information, but you're getting really meta at that point. I'm not going to get too far into this because it's basically the realm of sociology, which is pretty much just for college scholarship athletes.
