As we in news and media attack the platforms and their every misstep — and there are many — we need to turn the mirror on ourselves. It was news media that polarized the nation into camps of red v. blue, white v. black, 1 percent v. 99 percent long before Facebook was born. It was our business model in media that favored confrontation over resolution. It was our business model in advertising that valued volume, attention, page views, and eyeballs — the business model that then corrupted the internet. It was our failure to inform the public that enabled people to vote against their self-interest for Trump or Brexit.
