Thank you for those (and the first link especially). That's more in line with what you said originally.

That said, it is a bit suspect that it's always the same reporter writing about this topic. I'll have to dig into this some more, thanks!

Wow, nice observation, it's bizarre that they are all from the same author. I wonder if that's due to domain familiarity, small sample size, or some more nefarious reason (she does have a book published on the subject?). I wonder how common this sort of thing is.

Doesn’t seem that unusual to me — she’s a columnist for the New York Times, and needs subject matter to write about. It only makes sense to have interests that are then reflected in multiple weeks’ columns. You can see her bio at Amazon: https://www.amazon.com/Gretchen-Reynolds/e/B001KHP9G2

People who exercise often have strong biases confirming the efficacy of the type of exercise that they enjoy most.

Weight training, running, Crossfit, yoga, martial arts - I've heard enthusiasts of all of these forms of exercise claim that it's absolute best form of exercise that makes all other unnecessary.

Aside from any journalistic biases, I assume that the author really, really likes running.
