The findings reinforce prior studies that have shown that trying to debunk skeptics never works, and perhaps now we know why. Conspiracy theorists don’t join social networks to learn, they join them to hear comforting reinforcements of their own ideas. And if you disrupt their happy place with scientific facts, you’re not going to get very far. The study also suggests that social media, especially Facebook, has provided a particularly strong breeding ground for extreme ideas by creating a forum for loners to establish large communities that echo similar, strange beliefs.
