"While there’s a lot individuals can do to identify misinformation and reduce their role in spreading it, the main culprits are Twitter, Facebook and other platforms engineered to maximize speed, engagement — and corporate profits, said UW associate law professor Ryan Calo.
All of the platforms have taken steps to tamp down the spread of dangerous health misinformation during the pandemic, by highlighting reputable sources or being quicker to delete bogus material, he pointed out. That shows they can do it — if they are motivated.
“I think these platforms need to take the lion’s share of responsibility for what’s going on, because their business practices and their platforms are what is enabling these lies to get halfway around the world before the truth puts its shoes on,” Calo said, paraphrasing an old saying."
