I am autistic, but highly functional. With some minor compulsions about counting1. I have an intense interest in languages2 and their structure which has made me able to convey ideas very clearly on the long run. I have been tested by professionals a few times and have been found to have an IQ at least three standard deviations3 from the normal—tilting upwards. I have taken a few tests to measure the higher spectrum of IQ, but three years after the last one the efforts to norm it have thus far proved futile.

2. Be them natural or artificial languages, human or machine. This includes mathematics.
3. Which is pretty useless to accurately designate anything above near-genius intelligence.
