After initially misreading the above, I realised that going to 3-level CR could be very worthwhile. I'll reword the above into a 3-level CR context and also change the strategy slightly: 1) Identify the two frontrunners, and pick your favorite among them. 2) Give your favorite frontrunner plus the runners who you think are better than your favorite frontrunner a score of 2. 3) Give your less favored frontrunner plus the runners who you think are worse than your favorite frontrunner a score of 0. 4) Give the other runners a score of 1. Step 4 is the "major" bit. I had missed out the runners who are in between the two frontrunners. However, I don't think 3-level CR is as useful in a 0-info context. For the situation I was thinking of using a voting method on, which is why I joined this mailing list, I think the context is practically a 0-info situation. In the 0-info case, the middle level is useful only for runners who are exactly in the middle or at least near the middle. For the other runners, you want to maximise or minimise their score in order to ensure your ballot gains something. But how near the middle is near the middle? Hmmm. Thinking about the full-info case, wouldn't it be better to give the runners identified in step 4 a score of 2? This reduces the 3-level CR method to just 2 levels (i.e. Approval method). I suppose it depends how desperate you are to make your less favored frontrunner lose. However, giving a 2 to the runners who are in between the two frontrunners means that they are more likely to defeat your favorite frontrunner, who you think is better, or worse your favorite. Hmmmm, Gervase. ---- Election-methods mailing list - see http://electorama.com/em for list info
