Always suspected that Dunbar's number and the "two-pizza team" is too good to be true, but couldn't point to a study for this. Seems people tried to replicate the study in humans but the interval is too large: https://t.co/Hb8ags3zuo https://t.co/sm4oG4sja

Interesting study on Dunbar's number. While Dunbar's original research is not really a bad take in itself, the popularization of the number became one through things like the famous "Monkeysphere" Cracked article.
