Which knowledge to use?

I have had a picture in the front of my notebook for a while now and finally had the opportunity to turn it into something a bit more presentable.

It talks to a concept along the lines that people make subconscious decisions about what sources of knowledge and information they will use to find answers.

This ranges from a person's own tacit and explicit sources, personal networks, local resources (team mates, team folders, colleagues) to enterprise wide sources and beyond the walls of the organisation.

It mainly talks about some of the factors that effect which sources people decide to use. These can be based on trust, ease of access, ease of use, reputation and previous experiences.

No empirical evidence to back this up. Just a concept I thought about a while back that makes sense for me. What do you think?

Thanks
