Actually our brains have been shrinking since the stone age.

Quote:numbers: Over the past 20,000 years, the average volume of the human male brain has decreased from 1,500 cubic centimeters to 1,350 cc, losing a chunk the size of a tennis ball. The female brain has shrunk by about the same proportion. “I’d call that major downsizing in an evolutionary eyeblink,” he says. “This happened in China, Europe, Africa—everywhere we look.” If our brain keeps dwindling at that rate over the next 20,000 years, it will start to approach the size of that found in Homo erectus, a relative that lived half a million years ago and had a brain volume of only 1,100
Trump voters may be a sign of things to come.
One theory on this, the one I hold to, is that the human brain is shrinking because it's rewiring itself, becoming denser and more efficient so a smaller brain can hold more information, not because we're becoming more stupid.
