Neocortex matters more than social enhancements à la Facebook, says Robin “Dunbar’s number” Dunbar in a recent article. Will these results get him a Nobel Prize?

In 1992 Robin Dunbar proposed a rough estimate of 150. But the “Dunbar’s number” pretty much doubled in 1998, when Peter Killworth suggested a mean personal network size of 290. And in 2010 that number doubled again, as Matthew Salganik came up with 610 personal. So who says 1,200?
