Other well-known advocates of the anticipatory approach include Newt Gingrich, Heidi Toffler, K. Eric Drexler, and Robin Hanson. They all advocate approaches where the public, not just experts, participate in this "anticipation".
To do this anticipation, prediction markets and other risk management techniques may be embedded into bureaucracies and agencies to overcome the groupthink inherent in such bodies, which makes it quite difficult for them to anticipate uncomfortable future events. The FutureMAP program of the Information Awareness Office program of the United States government proposed a prediction market prior to its cancellation on July 292003.
Bioregional democracy can appear as a variant of anticipatory democracy in that it anticipates (using a similar scientific process) the ecological health outcomes of any given action. However it usually relies more on far less fragile means, and less on compared measures and quantities:
An alternative, deliberative democracy, may combine with either the anticipatory or the bioregional model. It relies less on formal models and a market system for betting on future events, and more on discussion.
Deliberative, anticipatory and bioregional approaches can all be considered variants of participatory democracy with different thresholds of ease of participation, burden of proof, concern for non-human life or future generations, and reflection of participants' tolerances versus preferences or ideals of truth. Sometimes a deliberative model is described as more "left" and an anticipatory model as more "right". Those who wish to avoid this debate and see merits to both approaches, e.g. Greens, usually prefer the generic term "participatory democracy." This term has become fundamental to green politics itself. Other terms which likewise have more specific associations with advocates or methods include: grassroots democracy, semi-direct democracy, consensus democracy.
