Exact sizes and universality of layered egocentric social networks

Determine the exact sizes and cross-context universality of the finite, layered patterns of socially relevant relationships associated with Dunbar’s number.

Background

The paper discusses evidence that human cognitive and temporal constraints limit the number of active, socially relevant relationships and produce finite, possibly layered egocentric networks. These layers are associated with Dunbar’s number and are relevant to understanding social support, diffusion, inequality, and well-being.

Although the broader claim that attention, time, and cognitive capacity constrain relationship maintenance is presented as robust, the paper identifies the precise sizes and universality of the proposed layers as unresolved. The open issue is whether these layer sizes generalize across populations, contexts, and forms of social interaction.
