Fertility and intelligence is only half of the picture. (an important piece, though) What about intelligence and life expectancy of the individual and of children? Also, what about other types of intelligence? IQ, EQ, etc? While very complicated, a multigenerational sampling with more information is really required. There is so much more to this picture, than a negative fertility correlation.

There is only one intelligence, only one factor that can reliably predict future life outcome. It's what we meant by IQ. All the other BS is just a politically correct invention to avoid inconvenient facts. If high IQ individuals are becoming more and more rare as generations pass, the world of the future will not be a very pleasant, nor at least functional, place to live. Internet, sewage, rockets... these are not things created by "high EQ individuals".

It doesn't seem like it.

First, let's say you have two brains, one has IQ 160, the other has IQ 60. They are the same volume, neither suffers any brain damage. What is the IQ 60 brain doing?

Honestly, it seems like the Flynn effect has been a disaster upon the human race, when you look a bit better into history. People did live happier lives. All the supposed horrors seem to be a myth. There was more peace, love, honesty and goodness. Maybe they did know better.
