My strong guess of where these numbers come...

“2 friends” is probably drawn from core discussion network from the US General Social Survey (“Who do you discuss personally important matters with?”)

“Demand for 15” seems a lot like Dunbar’s # for human’s cognitive capacity for 15 good friends.
Mark Zuckerberg says Meta's chatbots will supplement your real friends: "The average American has fewer than 3 friends ... but has demand for ... 15 friends" (h/t x.com/romanhelmetg...)

Not that I want my first ever post to be self congratulatory, but it’s a real honour to receive the Garry Robins Award at the Australian Social Network Analysis Conference #ASNAC #INSNA #SNA
