[EM] STV vs Party-list PR, could context matter?

2012-02-17 Thread David L Wetzell
It seems to me that a common sense solution would be to base which gets used on the propensity for voters to be informed about the elections. Also, the two types seem to be bundled with different types of quotas. STV gets marketed with the droop quota here in the US. I'm not complaining because

For those who feel that Bayesian Regret is the be-all-and-end-all measure of voting system quality, that SODA's BR for 100% strategic voters will beat all other systems, including Range/Approval. For those who feel that Condorcet compliance is the be-all-and-end-all, a majority Condorcet winner, o

But why would you want all these differences and complications? If you are going to use STV-PR for some of these elections, why not use STV-PR for all of these elections to the various "representative assemblies" (councils, state legislatures, US House of Representatives, US Senate). STV-PR wor

IRV's got a first mover advantage over SODA and to catch up you need to convince someone like Soros to help you market it. It wouldn't matter if you got the whole EM list to agree with you that it was hunky-dory. But in the context of a 2-party dominated system, there aren't as many serious candi

It is because first-mover counts a lot that we've been stuck with FPTP in the US for such a long time in contrast with countries with younger democracies... I never said it was all that counts, but it counts a good deal, as I metaphorically allude to by emphing the diffs in Ps over the diffs in Xs
