Is there some research on a law of 5? As in 5 is the max amount of connections and permutations in a group of people which it's possible for a member to work out the permutations?
For example in a group of 3 me bill and Alice I can model bills view of me and Alice alone, me and Alice together, me Alice and bill together, etc etc
As far as I can tell the vast majority of the scientific community still consider it valid.
I also discovered in searching that you're talking about David Graeber. I recently read his "Bullshit Jobs" book because someone on here cited it. It was one of the worst books I've ever read. It was clearly a contrived political manifesto (I suppose for "anarchy") with the thinnest veneer of popular science wrapped around it. I think ancient aliens probably got more anthropology correct.
So if you're going to appeal to an authority instead of actually transmitting the argument yourself then David Graeber seems like probably one of the worst you could pick to cite.
oh so you didn’t read the research. googled one of the non graeber papers for ya since you decided you didn’t like the guy for his politics https://twitter.com/davidwengrow/status/1116786595351470080?... you can find the full contents on scihub. I trust you can overcome your appeal to the authority of popularly engrained opinions

Beyond a certain number it's not really possible.
