Intelligence is difficult to measure in an autistic person. I have areas of very high ability, as well as areas of retardation. I'm adept at solving problems, visualisation, memory, recording and storing information, understanding written language, spelling, and spatial relations. Then I have savant gifts in writing, drawing, and musical aptitude. I have a genius IQ, yet in other areas, such as auditory comprehension, figuring out other people's minds, deciphering the human code of behaviour, and remembering a long set of instructions, and knowing what the people in a picture are doing, I am retarded.
Society thinks that level of intelligence determines level of ability.
In Autism, that isn't true. I am unable to work at a job. I receive some help, and am trying to get more. I consider my disabilities just a part of me, rather than defects that make me less perfect. Perfect doesn't really exist, and the word 'perfect' is a relative comparative term, as is 'normal'.
