I’ve spent the past year interviewing dozens of doers inside social media and game companies—product managers, engineers, and members of trust and safety teams. Along with my research partner, Kellie Owens, I asked people the basic question: Do these companies think about well-being, especially that of young people, when they design new products and features?

The short answer was: not really. The longer answer has a lot in common with what Frances Haugen, now known universally as the Facebook whistleblower, told Congress last week.
