I'm not saying that not having a degree is a bad thing, or has any indication of person's intelligence. Honestly, I did not learn even a fraction in college of what I learned after it, by my own choices of educational direction and pure interest in various fields. But from experience, the people I know who haven't studied, often are bit touchy about the subject. For one, I thought I was worse than someone with a degree, before I got one. I guess it comes from having no experience with higher education first hand.
