"It does correlate to very negative performance (as it was initially designed to detect learning special needs)" It did a crap job detecting learning special needs with my son. Because he has a weird intelligence profile of being above 98% on some tasks and below 10% on other tasks, the IQ test simply wouldn't score him, and put him in the "he's not taking the test correctly" category. Yeah, not at all useful, thanks. There were plenty of other more useful tests however that teased out his learning difficulties and actually gave us useful information to help his education.
