The Evidence Hub: Harnessing the Collective Intelligence of Communities to Build Evidence-Based Knowledge

Conventional document and discussion websites provide users with no help in assessing the quality or quantity of evidence behind any given idea. Besides, the very meaning of what evidence is may not be unequivocally defined within a community, and may require deep understanding, common ground and debate. An Evidence Hub is a tool to pool the community collective intelligence on what is evidence for an idea. It provides an infrastructure for debating and building evidence-based knowledge and practice. An Evidence Hub is best thought of as a filter onto other websites — a map that distills the most important issues, ideas and evidence from the noise by making clear why ideas and web resources may be worth further investigation. This paper describes the Evidence Hub concept and rationale, the breath of user engagement and the evolution of specific features, derived from our work with different community groups in the healthcare and educational sector.

The Evidence Hub is a contested collective intelligence tool for communities to gather and debate evidence for ideas and solutions to specific community issues. By aggregating and connecting single contributions theEvidence Hub provides a collective picture of what is the evidence for different ideas, which have been shared by an online community.”

    The other required piece is about how to get a large majority of earthlings to seriously upgrade their criteria for what constitutes “evidence.” As stated here, and elsewhere: “You can have clear data, but people who are dug in on an issue just go out and select the data set that reinforced their predisposition.” (
