A lot of people are sceptical when a significant gap is mentioned between non-verbal and verbal intelligence . That is not actually that uncommon for people on the spectrum .

Autism and IQ Testing Bias

There may also be the case that the person has a large disparity between scores, larger than 1SD, and so in this case, a composite score isn’t useful. If we take someone like Feynman, who some may argue had autistic traits and may have been on the spectrum, had a verbal intelligence around 115 but one psychologist estimated his non-verbal abilities to be the equivalent of 180–190. As you can see, this is a massive difference and a composite score is useless, hence why his 125 FSIQ is unrepresentative among other reasons. In this case, the best option is to not give a composite score but just rely on the domain specific scores.
