A project of integration of four fields of knowledge may have the potential to effectively raise the average of functional IQ for an entire population.
The IQ of a population is often considered a bell curve. More people have average intelligence and fewer have either high or low intelligence. In fact the curve is more like a Poisson curve, because very low intelligence usually goes with metabolic defects, birth defects and injuries that are lethal. Thus the low side of an IQ curve is not the same shape as the high side.
None the less, if you could do anything to raise the IQ of most individuals by some amount, not only would you anticipate increasing the mean IQ but the number of individuals with higher IQs would rise proportionately even more greatly.
