This completely misses the point, for a simple reason: humans (uniquely among Earth lifeforms) are subject not only to genetic/epigenetic evolution but also to memetic evolution. In fact, these two evolutionary levels are tightly coupled, as evidenced by the very good match between phylogenetic trees of human populations and of languages.
It makes no sense to talk about human IGF, any definition excluding memetic component is meaningless. Now, if you look at IGMF optimization a lot of human behavior starts making a lot more sense. (It is also worth pointing out that memetic evolution is much faster, so it is probably the driving factor, way more important than genetic. It is also structurally different, more resembling evolution in bacterial colonies—with organisms swapping genes and furiously hybridising—than Darwinian competition based on IGF.)
