Software for democratic decision making, quickly reviewed

Some notes taken on the first meeting of the socialswarm people.

Oh and BTW, we take only open source into account. Who'd ever like to use a closed source voting system?

20:59  <lynX> what i dont like about adhocracy is superficial: 1. it includes google scripts
21:00  <lynX> 2. people turn off delegations just so they dont need to worry about user registration
21:46  <codethief> lynx: but we're not here for trying out *liquid* democracy. we're here for decision making.
21:48  <lynX> ct: ack, delegations may not be needed for this job

Vote calculation methods

These small descriptions are courtesy of the website.

About the Schulze method

The Schulze method is a preferential voting system. It is based on the Condorcet method but includes a set of methods for resolving "circular" defeats.

The Schulze method is also known as Schwartz Sequential Dropping (SSD), Cloneproof Schwartz Sequential Dropping (CSSD), Beatpath Method, Beatpath Winner, Path Voting, and Path Winner.

About Simple Cordorcet Voting

Condorcet allows voters to rank candidates in order of preference. If there is a choice whom voters prefer to each other choice when compared to one at a time, that choice will be the winner.

There is a family of Condorcet methods. This method is referred to as "Simple Condorcet" to distinguish it from the Schulze method which is another Condorcet system.

About Approval Voting

Approval voting is a voting system in which each voter can vote for as many or as few candidates as the voter chooses. Approval voting is a limited form of range voting, where the range that voters are allowed to express is extremely constrained: accept or not.

About Borda Count

Borda count is an election method in which voters rank candidates in order of preference. The Borda count determines the winner of an election by giving each candidate a certain number of points corresponding to the position in which he or she is ranked by each voter. Once all votes have been counted the candidate with the most points is the winner.

About Plurality Voting

Plurality voting selects the winner who has received the most "number one" votes, regardless of whether or not he or she has a majority of votes.

Plurality voting is also variously referred to as, "first past the post," "winner-take-all," "majoritarian" or "simple majority" voting.
