Sometimes.  But if wonder if it's merely that social media allows us to see just how stupid the average person is whereas prior to social media, one would generally only associate with others of like intelligence. For example we are all fit and therefore smart. :) With the Internet you can instantly view thousands and thousands of comments from random people that you typically would not have had access to in years past.  And so throughout history maybe  there have always been many more idiots than smart people and we've gotten this far so hopefully we'll be OK.   On the other hand I worry that fat in the brain is accelerating the rate of stupid.  One thing we can be sure of is that we will all outlive them and enjoy our lives more than they ever will before they finally plop to their deaths like the colossal cow turds they are!
