Tech created a global village — and puts us at each other’s throats

As we get additional information about others, we place greater stress on the ways those people differ from us than on the ways they resemble us, and this inclination to emphasize dissimilarities over similarities strengthens as the amount of information accumulates. On average, we like strangers best when we know the least about them.

The effect intensifies in the virtual world, where everyone is in everyone else’s business. Social networks like Facebook and messaging apps like Snapchat encourage constant self-disclosure. Because status is measured quantitatively online, in numbers of followers, friends, and likes, people are rewarded for broadcasting endless details about their lives and thoughts through messages and photographs. To shut up, even briefly, is to disappear. One study found that people share four times as much information about themselves when they converse through computers as when they talk in person.

Progress toward a more amicable world will require not technological magic but concrete, painstaking, and altogether human measures: negotiation and compromise, a renewed emphasis on civics and reasoned debate, a citizenry able to appreciate contrary perspectives. At a personal level, we may need less self-expression and more self-examination.

Technology is an amplifier. It magnifies our best traits, and it magnifies our worst.

Nicholas Carr writing in the Boston Globe
