Speaking about grammar schools and how being in favour of them is likely to be against your interests.
"49.999 recurring per cent of the population are below average intelligence. By definition - the average is the midpoint."
Hmmm... whatever the average IQ is (100?), I suspect that more than 0.000001% of the population are at that level.

Actually, having thought about this, he may have a point. Not sure.
How does he define intelligence?
When you ask people this they usually describe themselves.

I think I was getting too hung up about this and maybe he was too.
The point he does have is that whatever your view on grammar schools, most people (about 75%?) aren't going to get in.
Personally, I'm in favour of any system that raises standards.

By definition - the average is the midpoint.
That isn't necessarily correct.
The median average is the middle figure when all the figures are listed.
The modal average is the most common figure in the list.
The mean average is the sum of all the figures divided by the number of the figures.
When most people speak of averages, they are referring to the mean average. Take three men, two of whom have £10 in their pockets and one who has £100. Their total cash is £120 and their mean average is £40. That means that two thirds of them have a below average amount.
The modal average is the most common number which is £10. Two thirds of them now have the average amount.
The median average is also £10 in this case.
The best way to look at IQ figures is to examine the standard deviation. (I wonder how many people read this far?)

Yes, aware of all that (btw I was quoting JO'B).
Even taking the median figure, unless you work to many decimal places, a lot of people will have the same figure.

Sorry, I was just bored. You are approximately correct. 
Surely it's in everbodys interest to make sure the brightest learn as fast as they are capable of going and not having to wait for the less bright to catch up,don't believe you should be cut of it at eleven should be able to be promoted at the end of term and like wise relegated if you are not hacking it after all the world is a very competitive place.If a child is not academic he will have other talents and schools should concentrate on bringing these out as a lot of public schools do now.I thought the opposite of this when I was young but more working class kids moved upwards back then they seem to do now.No doubt someone will put me right on this and fair enough if they do as it's only my personal oplnion.
digdeep - I agree with you in theory.
JO'B, however, would say that it's not necessarily the brightest kids who get in. It's the children of "sharp-elbowed" middle class parents who can afford to pay for after hours private tuition to get them through the 11+ exam.

True but they are doing that with the best state schools now by moving near to those schools perhaps a more accurate test of a child's intelligence is needed,very hard to get fairness to all in a very unfair world.
"Hmmm... whatever the average IQ is (100?), I suspect that more than 0.000001% of the population are at that level."
He's kind of correct but a total ars3 of a man.
What it comes down to is the difference between a summation and the more calculus defined way of doing it where there are infintely small amounts of gradations of IQ to the point where like 1 or 0 people may have the exact average IQ.
Though it's a bell curve so actually virtually horizontal at that point, and anyway the measure is pretty vague so if it was all the same test say on 0-100 mark you'd have the LARGEST amount on the 100 mark, if it was granular to that.
BTW yes the average IQ is supposed to be by definition 100.

I'm confusing you by saying test 0-100 and IQ 100 but I hope you get the point :)
