  • I'm wondering why the Times isn't featured

    Perhaps the authors didn't want to pay their subscription? :)

    They may have seen it as a methodological problem if one paper is behind a paywall, but the others aren't. I assume they didn't buy any of the other papers' paper editions but monitored the web-sites only; perhaps it would have got too expensive to do the study if they'd paid for paper editions and paywall access. Just speculating, I have no idea what the real reason is.
