Evaluative Proportional Representation

From electowiki
(Redirected from EPR)

Evaluative Proportional Representation (EPR) is a proportional extension of Majority Judgment, devised by Stephen Bosworth.[1] It is highly related to the Expanding Approvals Rule.

Unlike EAR, it doesn't aim to ensure proportionality by seat count. Instead, EPR outputs a set of winners along with the weight that each winner should have in a collective decision process (e.g. in a council or by parliamentary procedure).
