Epistemic democracy is the "doctrine of the wisdom of the multitude." - wikipedia
Epistemic democracy is:
a recent paradigm in democratic theory. Put generally, in the epistemic interpretation, democratic decision-making processes are valued at least in part for their knowledge-producing potential and defended in relation to this.
Epistemic democracy further combines deliberative and aggregative approaches to democracy but shifts their focus towards an outcome-oriented consideration for how well democratic procedures such as deliberation and voting help democratic decisions approximate a procedure-independent standard of correctness.
