It sounds like the type of trust you are looking for here is 'referential trust.' Someone can be trustworthy by reputation alone; this is a trust carried through the intellectual capital network that is shown. Most people though do not rely on the formal network, the published bibliography, or the service or search engine that the IC network creates. We put more faith into the opinion of friends, and perhaps even casual acquaintenances, than we do in the formal sources.

This is carried in an informal social network. One that is different from three networks of Capital that you show. I'm not sure whether the barriers between the formal and informal networks are due to healthy skepticism or bitter experience. I am sure that the barriers exist and may well offer protection against the dominance of any one type of Capital.
