This will then have a knock-on effect on what is taught and how it is taught in order to keep up with this kind of 'demand' in certain areas. This will be tied to the kind of questions that are asked on the exams that select - heavily loaded towards right/wrong answers, 'grammar' and 'verbal reasoning' (IQ).
I suspect that much of this will revive the flagging IQ business anyway, with people accepting the idea that 'ability' is the same as doing IQ questions.
