Other roots of the current climate lie in trends in popular culture and technology, as detailed by Jonathan Haidt and some others. Perhaps the most obvious and pervasive influence is the internet. Today’s undergraduate students are the first to have spent their entire adolescence on social media, and there has been much analysis about its effects on them. Studies have shown that social media make relationships controllable but also (and therefore) much “thinner” and more superficial.
Also, by comparison, social media make face-to-face encounters feel much more threatening. For example—how do you just “block” a critic who is physically standing in front of you? You can’t. That’s why aggrieved parties have their interchanges online, where they can simply hit the “off” button to end it. Before hitting the “off” button, however, internet communication makes possible the kind of cutting insults and dehumanizing declarations that few feel able to make to someone’s face.
