From wikipedia: "A knowledge broker is an intermediary (an organization or a person), that aims to develop relationships and networks with, among, and between producers and users of knowledge by providing linkages, knowledge sources, and in some cases knowledge itself, (e.g. technical know-how, market insights, research evidence) to organizations in its network.
While the exact role and function of knowledge brokers are conceptualized and operationalized differently in various sectors and settings, a key feature appears to be the facilitation of knowledge exchange or sharing between and among various stakeholders, including researchers, practitioners, and policy makers."
Are think-tanks the ones acting knowledge broker in politics these days?
