it is partly a joke site; the name is a reference, along the lines of the Ig Nobel, to the Proceedings of the Natural National Academy of Sciences (PNAS).
apparently they do a mix of science for popular audiences (Honest And Reliable Data), and parody (Satirical Or Fake Data). i like the cut of their jib, and will happily return. thanks, boingboing.
If you look at presidents past that weren’t gray going in (W, Clinton, Obama), they all go gray during their term(s)… I’ve never considered that it is a ruse with hair dye, but rather an effect of having the stress of running our country for 8 years (in all of my examples)
I guy I once knew had a bit that went something like: “The problem with Bush isn’t that he’s evil, it’s that he’s evil and incompetent. When Nixon went out collecting orphans’ kidneys in his two-story-high fire-engine-red flame-belching Nixonmobile, you knew he’d be home with a grin and a bagful of kidneys before the killing rays of the sun cleared the horizon. Bush can’t even get that right.”
Well, it’s quite a coincidence that all those presidents had no gray at all when they first campaigned, but by the time they were in the office within a year or so suddenly had some distinctly gray hair. Obama, in fact, was accused of dying his hair gray during the latter part of his campaign, as a response to being up against the older McCain, because his hair so suddenly changed color. I suspect he simply stopped dying his hair.
This seems to be a fairly modern phenomenon - looking back, Carter had gray patches that got a bit lighter during his term and Reagan’s hair got darker by the time he left office.
