| While I found this quite interesting, and I'm as concerned about some of these trends as the next person, I was eerily reminded of some of John Robbins's stuff graphing meat consumption against incidence of diseases and his kind of casual thinking about causation. We have so many datasets available now that it's so easy to graph things against each other and notice things that may be coincidentally related, or even causally related, and then tell some kind of story about where the relationship came from. And I remember that there's even a funny web site that tries to underscore the difficulty in reasoning from these associations. http://www.tylervigen.com/spurious-correlations In this case, the n-grams chart really exemplified this for me. There are so many influences on the frequency of a word, including lexical substitution of a word by its synonyms, changes in spelling, and increased or decreased interest in a topic regardless of whether that interest is positive or negative. For example, check out the long-term decline in avarice in America! It's profound! https://books.google.com/ngrams/graph?content=avarice&year_s... Oh, wait, maybe we just stopped using the word "avarice" rather than the concept. :-) Or, during this Second Gilded Age, our society actually started to become less atomized: https://books.google.com/ngrams/graph?content=atomized&year_... ... or maybe we just moved away from calling the phenomenon that. |
Yeah, it's a fun website -- but you could say that about just about any claimed correlation.
Meanwhile, for those who have been around long enough to have a sense for the 'barometric' changes he's talking about -- the shift in the basic, underlying "we're-all-in-this-together" ethos has been not just noticeable, but profound. Probably a lot more work needs to be done to find a solid statistical basis behind this observation (if this is at all possible).
But by and large (aside from the singe n-gram example, which I agree smells like cherry-picking), it's not like his arguments are simply frivolous.
