A page linked to from that demarchy.html page, says: >Random selection is also called the lot system, the jury system or sortition. >>Demarchy can also be called statistical democracy. http://www.uow.edu.au/arts/sts/bmartin/pubs/89demarchy.html Approval gets so many winners wrong (different from (USA's and) the CVD's IRV that it be categorised as being a random method. Etc. PS. My comment about Hadamard matrices is somewhat irrelevant, but the matrices do have as many "+1"s and "-1"s, corresponding in a clear way to how in 1 winner Approval elections with 50 candidates, it would be maximally empowering (or minimally risky) to fill in about half of the checkboxes. E.g. if green plants are being designed and 10 changes are made to their genetics (maybe providing a resistance to insects), then less than 2**10 (1024) plants are needed, if the theory of fractional factorial designs in statistics are used (which uses Hadamard matrices). Possibly one enhancement might neutralise another. In a 3 winner Approval election where voters mainly wanted candidate A and B, they could easily split into two similarly sized groups, those that voted for candidate A but not candidate B, and those that voted for candidate B and not candidate A. For an individual to vote for both could the vote to lose its power. 10 candidate checkboxy Approval evidently has a vote-splitting problem that I was not seeing complained about. [3] Also, Approval maybe should fail a test of monotonicity, since this can happen: A wins with the added paper (ABCDEF) <---> A loses with the added paper (ABCDEFG) Unless someone objects, I'll say that monotonicity is not defined for methods that allow that to occur. No method is passed by a rule that is not defined. Thus Approval does not pass. Anyway, monotonicity seems to be an idea that is unimportant in the theoretical maths of preferential voting (it does not allow the trailing right hand side preference to be disordered. Whoever designed it in that way, i.e. to limit changes on the right (all the way to having a non-essential idea), may have also expected similar restrictions for the leading preferences on the left. Anyway, Approval is said to be not a preferential method. Mononoticity may, in any case, be undefined for methods that are not preferential voting methods (specifically, the Approval method).
