It’s not a new trend, it is common in non fiction writing. Everything Malcolm Gladwell writes is in this style, and the same for many non fiction business / self help type books.
"There’s this writing style in popular non-fiction that I’ll call the ‘Malcolm Gladwell method of shoving-a-story-in-your-face’. It substitutes argumentation for storytelling and anecdote, and in so doing sidesteps the difficulty of making a case, since the reader is too distracted by narrative to comprehend the point the author is actually attempting to make.
Whenever this happens, I take care to pay special attention, because often the point is banal, or flawed, or too inconsequential to stand on its own. (I happen to know this because I’ve used this technique a few times on this very blog, and I know from reader feedback how effective it is)."
It is annoying though when it get voted to the front page. You are expecting something that is interesting or insightful and it is just generic, repackaged investment insights/aphorisms/advice that is used as an indirect sales pitch to promote a likely equally mediocre investing service.
