Dunbar's number

Dunbar's number is Robin Dunbar's proposed approximate limit to stable human social relationships, perhaps due to brain size.

Presuming that Dunbar's number means that a person also likely only has room for a couple of people able to occupy specific domains.

For example, people may only be able to place trust in so many experts in a specific domain.

Dunbar Hacking is when an entity leverages this against people by replacing vital local resources with manufactured parasocial relationships.

  • Good summary of research.
  • The size of the brain itself or just the neocortex may drive limitations.
