McBride pressed the issue, noting that Facebook has an incentive not to challenge the ideological perspectives of its users: If they feel more comfortable with their News Feeds, they're going to spend more time scrolling through them. And if they spend more time scrolling through them, Facebook gets to show them more ads.“You want to keep people on your platform,” McBride said. “After two hours, I don't feel like I've chosen. I feel like I've been sucked in.”Brown pointed out that Facebook's News Feed algorithm responds to signals from users.“It's not that mysterious,” she said. “What shows up in your News Feed is based on the things that you like. Things you share. People you're friends with and that you follow.”“Isn't that a filter bubble?” McBride countered.“I'm telling you, that world existed long before Facebook,” Brown said, and recommended that users who want to be challenged cultivate a diverse range of ideological perspectives on their feeds.
