The combination of systems recommended by Common Good for decision-making in Common Good Communities is very close to what people do informally within families and groups of close friends -- people we care about and share common interests with. If you're going on an outing, for example, and want to decide where to go, here's what you do: you talk about it, you take everyone's preferences into account (whether they are present or not), and you generally don't go where someone just won't go. That's what the recommended Common Good decision system aims to do.
By combining the best of each of the systems listed here, Common Good Democracy will nudge society toward a more participatory, compassionate and effective self-rule. (See "How Is It Better" for an analysis of why this hybrid system is better than any of its component parts.) Every individual component of the recommended system has been used successfully elsewhere:
Penny vote is used by activist organization to poll the public on public policy issues. For example, Peace Action Coalition polls taxpayers every year on Tax Day to see how they would like their tax dollars to be spent.
Line-item veto is used by state governors in all but seven states in the United States of America.
Threshing sessions happen whenever people gather to discuss something, without trying to decide anything. This includes public hearings by corporations and government agencies and discussions in New England town meetings in which a new proposal evolves.
Internet voting has been used by France, the Netherland, Estonia, and Ontario, Canada. Some corporations, universities and other organizations also now use internet voting.
Instant Runoff Voting is used in Ireland, Australia, New Zealand, San Francisco, CA, Burlington, VT, Cambridge, MA and many other municipalities.
Grading is used in schools and for everything from movies to maple syrup. Slightly different grading systems are common in different countries and the Common Good Democracy voting system can be adjusted accordingly. The A B C D E system described on this website is intended for use in the United States and other countries where such letter grades are common.
