Does attention has any correlation to IQ? I mean is it possible to have an IQ of 180, but perform with IQ 120 because of lack of attention?

Anecdata, sample size 1: When I was a teenager struggling in school because of attention issues, a psychiatrist had me take a test which suggested so. IQ and a few memory/recall-related tasks measured a bit higher when I was medicated with Adderall than without it.

That should be controlled against simply repeating the test and simply giving "normal" people adderal during iq testing.

Do you remember the % difference?

Absolutely. 90% of HN readers do it everyday.

I'd assume so given that a large part of how IQ tests derive your score is based on how long it takes you.
