Over the past 75 years in America, and perhaps even longer in other lands, we have been subsidizing the reproduction of the least cerebral, while taxing the more intelligent to a point where they have far fewer children. We have also, since 1965, encouraged the immigration of a less skilled, less cerebral segment of the outside world, than we drew earlier.
Thus there has been a measured fall in school achievement levels, since the early 1900s. Thus there has also been a considerable "dumbing down" in our observed levels of political discourse. Contrast the Phd. thesis level of public political addresses in the 1840s, with the moronic 30 second sound-bite today. The public with little formal education, followed the oratory of Webster, Clay & Calhoun; while college graduates today, chant in unison, like Nazi robots at the slogans of an Obama!
The reporter's commentary that follows the common sense--so far as it goes--quotes from the geneticist, in the balance of the featured article, is itself an indication of the dumbing down of contemporary "analysis."

You just described the major premise of the movie Idiocracy.
Rent it. Watch it.
It will all be clear.
BTW, I compare “Bwando” to “Global warming”.
