It is a very sensitive subject and although statistics may be kept the analysis may not help correct perceived imbalances.

For a start different regions have different needs and some people bloom later in life or contribute in ways not related to IQ.

About a couple of months back a statistician caused more than a few problems when the comments on the numbers kept were upsetting to some people.

Ultimately people are people and a combination of motivations and abilities strengths and weaknesses. In my walks I have seen some that may not be as academically suited but as human beings and a precious resource this world is better for having known them.

Likewise there are those who are destructive and unhelpful and so on and as bad as they are they make the rest of us look good, really good. Yes society does need to step in at times and it can be a very hard call with no defined right or wrong answer, just a method of coping. Does that help?
