Governments are increasingly deploying participatory digital methods in policymaking. Several parallel developments have contributed to the rise of these methods. During the 2010s, participatory culture created digital spaces for the public to collaboratively create and share cultural artifacts, thus channeling their cognitive surplus into various participatory activities. This cultural shift toward a more participatory paradigm has also permeated other realms of society, including governance, and in particular policymaking. Meanwhile, the ubiquitous nature of new technologies has enabled asynchronous participation in collaborative projects on a massive scale. The proliferation of participatory practices in governance also follows a broader societal trend, in which various fields are moving from the traditional closed paradigm to a more open model.
