When I took the test, I got a 32, which didn't surprise me. I've given tests like that as a special education teacher. If you look at some of the questions, you can pick out patterns. A person with social anxiety will score high also because many of the questions have to do with social interractions - that's me. Probably the reason I didn't score higher is that I'm a fairly creative person. Military type people who follow strict rules and routines would probably also score higher than average becuase of that rigidness. Kids who have spent all their lives in front of a TV or video game system might have a higher score because they haven't developed their imaginations. Things like that.
Tests like that are indications which, taken with other factors, help in diagnosis.
