I'm not sure, but from the fact it was written by Tierney (who used to be what I thought of as the gently-conservative voice on the op/ed page) and has a generic title under which it appears ("Findings"), I suspect that functionally it is an editorial. Might be more clear in the print edition, but this is probably his recurring column on whatever vaguely scientific he wants to write about, which just happens to have gotten a lot of attention this week.
