Re: [EM] Least Additional Votes. The importance of strategy.

2005-03-17 Thread Juho Laatu
Hello Eric, I think many people might really use strategy that is harmful to them but looks promising at first sight. They might falsely think like in the lines of the Borda method: "last position in the ballot gives least points" Or in terms of ranking: "one negative point to the last candidat

Hello James, You wondered how familiar I am with different strategies etc. I have studied the voting methods for quite some time and I have visited also Blake Cretney's web site. I think I know most of the basic stuff but unfortunately have not had time to follow all the details of the disc

Kevin-- You suggested that there could be a method in which a majority, who have transitive strict preferences among all the candidates, could ensure that some Y won't win, by alternately voting ">" and "=" in their rankings. You said that's a silly way of voting, and that, because a silly way o

[EM] Full Majority as Part of Strong Defeat

2005-03-17 Thread Forest Simmons
Jobst, the more I think about it, the more I like your idea (influenced by Kevin) of requiring full majorities for strong defeat. I don't think that we lose any of the basic properties, and it solves Kevin's 49C, 24B, 27A>B problem without the additional randomness that I was beginning to accep
