Although the piece linked below profiles only three people, it illustrates I think the main problem with social media: It doesn’t in itself radicalize people, instead it hatches them. IOW, they were already radical, they just need a place where they can find other like-minded individuals who won’t challenge them - because they don’t want to be challenged; they want, need acceptance (and, well, fame or more accurately, notoriety. It’s not all that different from middle school, really, the fear of being a reject.)
We have created a Star Wars civilization, with Stone Age emotions, medieval institutions, and godlike technology. We thrash about. We are terribly confused by the mere fact of our existence, and a danger to ourselves and to the rest of life
― Edward O. Wilson, The Social Conquest of Earth
Facebook groups for like-minded people are where lies begin to snowball, building momentum, gaining backers and becoming lore. Organizers refine their messages and titillate followers with far-fetched predictions and analysis, often recasting Mr. Trump’s loss as part of a master plan to get re-elected.
It’s hard to determine the extent to which Facebook caused this hyperpartisanship or simply stumbled into it. Did Facebook cultivate more extreme beliefs or simply take what was already simmering and thrust it into the open?
Mr. McGee argued that he always thought this way. Before Facebook, he said, he watched conspiracy-laden videos on YouTube. Facebook merely helped him find his people.
“People are engaging me, encouraging me to share what I think, but these are the inner workings of my mind,” he said. “I’ve been feeling this way for years. That’s why it’s so easy for me to make posts, because I’ve been suppressing this stuff forever.”
And yet when he talks about Facebook, he focuses on algorithms and optimization, not community or ideology. It’s worth considering: Would he be attempting to influence others so forcefully without Facebook’s incentives?
