I see you're one of those - the type who keeps banging his head on the wall thinking he's always right, despite not having a clue. You may have studied psychology at college but obviously not very well, because you are burbling total bullshit. 90 is the lowest score in the average range of 90-110, and the standardised tests developed decades ago were specifically designed that 100 was the average for everyone,. with ranges from as low as 50 or more, up to Bill Clinton scores of 180+.
And I will continue to comment on other peoples IQs (yours does not seem to good, for example, if your comments are anything to go by).
On the other hand, my own IQ is 154, measured by Mensa and a hospital in the States.
And I don't need a lecture on savants, thank you. I started the first UK registered charity for people with AD/HD in 1992, and we had plenty of them.
BTW - DICKHEAD! :-D :-D
