I don't know what's "good" or "bad". Depends on if you want to be autistic or not! (it's a medical/psychological/social condition. Very interesting short definition here:
http://en.wikipedia.org/wiki/Autism) I've worked with autistic kids in the past and the ones who are not high functioning usually have a very hard time in life. Some are almost catatonic (which would be off the charts on this little test) with a score of 50 being maxxed out for a barely functioning autistic person. I'd say, the lower the score the better. Check out the brief definition. It's fascinating (and very sad).
