"I do think social media is one of the fundamental problems that we're dealing with right now," former Sen. Ben Sasse says in an extended interview with Scott Pelley. " It doesn't encourage a lot of self-scrutiny. It doesn't encourage a lot of humility.” He adds that social media reinforces an us-versus-them mindset: "We're definitely right, and they're definitely wrong,” he says, noting "that tribalism makes us pretty stupid.” #bensasse #uspolitics #socialmedia
