Robin Dunbar / 罗宾·邓巴

Robin Dunbar / 罗宾·邓巴 enters the wiki through 83.梳毛、八卦及语言的进化：人际关系“邓巴数”，咱不服不行, where [[MihuanChishu|蜜獾吃书]] presents him as an evolutionary psychologist associated with [[DunbarNumber|Dunbar Number / 邓巴数]] and the book [[GroomingGossipAndEvolutionOfLanguage|《梳毛、八卦及语言的进化》]]. The episode uses his work to argue that language, gossip, and everyday conversation can be understood as social-bond maintenance rather than as trivial leftover speech.

The page is source-scoped. The episode treats Dunbar’s model as powerful and memorable, but also reminds listeners that evolutionary explanations, especially around sex differences and courtship behavior, should not become deterministic judgments about individuals.

Key Claims

• Dunbar is presented as the theorist behind the approximate 150-person relationship-capacity claim.
• His language-origin argument ties together primate group size, grooming time, neocortex capacity, and human conversation.
• The episode uses Dunbar to revalue small talk, gossip, art, religion, and podcasting as relationship-maintenance systems.
• The wiki should keep Dunbar’s claims as explanatory models, not as hard limits or moral rules.
