The first known implementation of a wiki survey was in 2010,[4] and they have been used since then for a variety of purposes such as facilitating deliberative democracy, crowdsourcing opinions from experts and figuring out common beliefs on a given topic.[5][6][7] A notable usage of wiki surveys is in Taiwan's government system, where citizens can participate in crowdsourced lawmaking through Polis wiki surveys.
Wiki surveys facilitate collective intelligence by allowing users to both contribute and respond to the survey, as well as see the results of the survey in real time. They can be seen in a more general sense as a tool for establishing consensus in large volumes of people. Wiki surveys mainly differ from consensus-building in comment sections by using a heuristic which determines the order of questions for each participant that aims to maximize consensus, not allowing replies to questions and providing visualization tools to better understand consensus.
