That's a ridiculous headline to derive from analysis of published article with title "The spreading of misinformation online".

Sure the idea that Facebook makes us dumber might have some truth in it. But it cannot be fairly evaluated unless one proves that the alternative Network Television or Grandma email forwards were not making us even more dumber before Facebook rose to prominence.

I think the problem with the article is that it doesn't dig deep enough.

For example, Facebook news feed is driven by an algorithm to push posts you are likely to be interested in. Liking an anti-vaccination post or anti-immigration post will surely result in more similar content in your news feed.

So Facebook inadvertently might be reinforcing confirmation bias more than anything else due to content being filtered and personalized to you only.
