If our assumption that communication brings people together were true, we should today be seeing a planetary outbreak of peace, love, and understanding. Thanks to the Internet and cellular networks, humanity is more connected than ever. Of the world’s 7 billion people, 6 billion have access to a mobile phone — a billion and a half more, the United Nations reports, than have access to a working toilet. Nearly 2 billion are on Facebook, more than a billion upload and download YouTube videos, and billions more converse through messaging apps like WhatsApp and WeChat. With smartphone in hand, everyone becomes a media hub, transmitting and receiving ceaselessly.
Yet we live in a fractious time, defined not by concord but by conflict. Xenophobia is on the rise. Political and social fissures are widening. From the White House down, public discourse is characterized by vitriol and insult. We probably shouldn’t be surprised.
For years now, psychological and sociological studies have been casting doubt on the idea that communication dissolves differences. The research suggests that the opposite is true: free-flowing information makes personal and cultural differences more salient, turning people against one another instead of bringing them together. “Familiarity breeds contempt” is one of the gloomiest of proverbs. It is also, the evidence indicates, one of the truest.
