From Glenn Harlan Reynolds in The USA Today, Social media threat: People learned to survive disease, we can handle Twitter:

Likewise, in recent years we’ve gone from an era when ideas spread comparatively slowly, to one in which social media in particular allow them to spread like wildfire. Sometimes that’s good, when they’re good ideas. But most ideas are probably bad; certainly 90% of ideas aren’t in the top 10%. Maybe we don’t know the mental disease vectors that we’re inadvertently unleashing.

Maybe there are some lessons for us here. We don’t know much about the spread of ideas, or what would constitute the equivalent of intellectual indoor plumbing. (Censorship isn’t enough, as it often just promotes the spread of bad ideas that people in power like). Over time we’ll learn more. Maybe we’ll come up with something like the germ theory of disease for ideas.

Where we can do something right away is with the equivalent of nutrition. Traditional training in critical thinking — the sort of thing the humanities used to revolve around, before they became focused on “social justice” — seems like it would be a useful protective. A skepticism regarding groupthink, ad hominem arguments and virtue signaling would likely offer considerable protection against the sort of mass hysteria we seem increasingly vulnerable to. Likewise, a social consensus on important ideas — the kinds of things we used to teach in civics classes — would help.

Better nourished minds are likely more resistant to social-media contagion.


An excellent and creative piece.  A creative writer can find illumination in seemingly unrelated ideas.  Read the whole piece.
