Mr. Charlton needs to add an "e" to his name and change it to charleton, because he is one. Anybody familiar with the gaussian distribution of intelligence knows that he is full of it.
The IQ curve may not be the issue in this discussion. Given that high IQ children can and do occur in families with lower IQ scores, is not the real issue whether a high IQ child is able to actualize the potential which such an IQ inherently confers?
In short, do the better schools admit based on IQ and performance? Or has socialism inspired political correctness been allowed to force admission of those who can not possibly be graduated without lowering academic standards?
