If anyone would like to explore the topic a bit further try "The Influential Mind" by Tali Sharot. It was on FT's short list for best of 2017. It's a quick easy read. Gladwell-esque. The difference iis, she is an actual scientest who works in that field. Tho' perhaps that makes her bias? ;)

Two things to add:

1) You might be interested in the book The Influential Mind. While she doesn't come out and say it directly, the bizarre state of our digital lives (i.e., social media) has quite a bit of reasonable (scientific) explanation.

2) The irony of the homogenized "wisdom" is that these same entities are personalizing so much that the shared / collective experience is being diminished. Perhaps it's easier to build mono-minded on top of a disheveled and disorganized foundation?
