I've done a bit of reading about Dunbar's Number and some of the alternatives (Bernard-Killworth value is in in the 200s, for example). Assuming that the concept of a limit of the number of people one can maintain a stable relationship with is valid, regardless of the specific number, is that number global for a person or is it segmented?
For example, a person may exist in multiple social groups. Is 200 the number of relationships across all of social groups or can a person segment and maintain 200 relationships within each social group or social context? Examples of social contexts may be work/professional, home/family, and any number of friend or social groups.
