I don’t know. I think he’s made a couple of good points. Especially because, yes, YOU know you should expose yourself to a well-rounded variety of news sources, and *I* know I should expose myself to a well-rounded variety of news sources, and while it would feel really great to say I believe most people realize this, it would be a bald-faced lie.
I feel like a significant percentage of Americans have stopped most meaningful reading since the advent of social media. I mean, what’s always with us? Our phones, right? When we have 3 minutes to slap together, are we searching out a Times or Journal or are we flipping through the top stories on Medium or Facebook?
It’s a matter of convenience, and we’re lazy. People want their news delivered in bite-sized juicy morsels that are easy to share with friends.
It doesn’t make social media responsible for our decisions. It just means we’re (as a whole) lazier than we used to be and we utilize social media to avoid having to exert effort. Which means we may, or we may not, be exposing ourselves to the whole story.
