Here, just for the hard of understanding. It plainly states that IQ tests were specifically designed so that an average score is 100. The more one varies from that mean, the more standard deviations there are.
In my case, my IQ is 3 SDs above the mean, meaning (if you know your statistics), that it is in the top 0.5% of the populations.
I take it you remember your sampling theory, eh?
In your case, with your sad level of knowledge (no surprise with a US degree) perhaps you have a negative SD. :-D
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.
I think you'll find the roundabout was a UK invention, where they drive on the left. The US has a few but not many and people get confused with them there as well.
Anyway, driving on left or right should not affect how to use a roundabout, which is very simple if you have a brain.
however, in my case, had you read my post correctly and not made assumptions, who also sends out unsolicited text messages to people in the hope of drumming up business.
