Doesn't matter what the stupid article says. Progressives were the first round earthers, evolution believers, accepting of new ideas and social changes. The conservatives resist all new knowledge, it's their nature. So they always be just a little dumber and more likely to believe that the earth is flat and that man made global warming is a hoax. As the rate of progress increases they will fall further behind. Eventually they will be considered mentally deficient and will need special classes and such.
