Somewhat popular idea in media (say movie "Idiocracy") and general perception of older generation is that people and society are getting dumber. It seems that even real studies show that "stupid" people have more children, than "smart". Does this mean that in some time "stupid" people will greatly outnumber "smart" whose part in population would decline?
If IQ is herediatary, does that mean that people in society are really getting dumber and modern society is doomed to fail, because of decline in intelligence or that is exaggerated myth?
I know Flynn effect, but if genetical basis of inteligence will decline, would it cease to work?
PS. I have nothing to do and do not suggest idea of Eugenics, just wondering is this perception of declining intelligence is true and are the effects exaggerated.
