- information flow is facilitated - word of mouth effect (e.g., being connected to people with useful information is a benefit)
- social ties may exert influence - some ties carry more weight (e.g., son of the President)
- social credentials - resources beyond an a single individuals' are available if necessary (e.g., politician endorsement)
- reinforcement identity and recognition - can provide support and public acknowledgment of one's claim of resources (e.g., maintenance of mental health and entitlement of resources)
I would agree and add that relationships among people add an additional layer of complexity that cannot be accounted using only individual centered metrics.
