I've often wondered, but I've just started reading "House Rules" and recognize so much of Jacob in myself, although no where near as severe. I just took this test and scored a 32, which, from what I can find online, is about the high end minimum of the spectrum.
I wonder what I would have scored as a child though. I am 45 years old, and I know that over the years we learn to fit in, and get better at reading people and mimicking what is considered "normal". I also know that if you "lie" often enough, you can convince yourself, eventually, that it's the truth. So, those things considered, I can't actually say that all my answers were completely accurate.
I CAN say for a fact that although I am very good at showing the proper expected emotion at the proper expected time, I very rarely actually FEEL the appropriate emotion. I am also VERY much a creature of routine, and if my routine is interrupted, it is disturbing and it takes me quite a while to get back on track. I am very OCD on a very few things, but I don't have the rituals or the feeling that something horrible will happen if I don't repeat an activity a certain number of times, as OCD people tend to do. Also, I'm a sloppy housekeeper, which would probably drive a truly OCD person insane. Plus I compulsively, almost absently, count EVERYTHING!
I am actually very well liked at work, but I'm not really very close to anyone. I can always make people laugh, but I recognize that I can also make people feel uncomfortable and be rather blunt about certain topics without really realizing it until later when I'm obsessively replaying the conversation in my head.
Probably this post by itself is proof enough....
