It's easy to minimize the problems with one's preferred systems, and focus on the problems with other systems you see as "competing" for mindshare. It's not even dishonest: the truth is that, compared to the giant issues with plurality, any good system has problems that are minor, but that on the other hand such minor problems would still be a hurdle in convincing voters to make a switch.<div>
<br></div><div>But I don't think it's getting us much of anywhere to argue this back and forth.</div><div><br></div><div>Let's imagine these minimizing-the-issues points were all granted, on all sides. Say Condorcet had negligible strategy, Range strategy were always unbiased, and SODA had no smoky rooms. (I think that all three propositions are close enough to true to use as an approximation.) I think that it's undeniable then that SODA would have the simplest balloting and Range the best results.</div>
<div><br></div><div>So I, personally, don't see the attraction of Condorcet when compared to other proposals. But... I'd rather find a way to agree than fight about it. In my other recent message, I suggested that we put forward SODA and one simple Condorcet method as the practical proposals in some statement which people here could sign on to.</div>

There has been quite a lot of discussion around the strategic vulnerabilities of Condorcet methods on this list recently. In general I think Condorcet methods are one of the least vulnerable to strategies, and in most typical elections their vanilla versions are simply good enough. In the case that people would start voting strategically there is one interesting defensive strategy that has not been discussed very much. The defensive strategy is to not tell your sincere opinions in the polls. Most Condorcet strategies are based on quite accurate understanding on how others are going to vote. If I expect someone to play foul play, I might just refuse to give the required information to them, and recommend others to do the same. (Also giving planned false information to mislead the strategists is possible, but more difficult.)<br>
<br>
This approach does not work about irrational voters that will bury anyway, just in case that might help. But the point is that in Condorcet elections the best strategy, in the absence of good information on the preferences, is to vote sincerely. In real life this strategy could be mentioned as a possibility in the case that strategic voting becomes threatening. The outcome hopefully is such that all parties, experts and media would recommend voters to vote sincerely and not try strategies. That would be better to all than having to live without the interesting polls. What do you think? Is this a way to drive away possible evil spirits and strategy promoting parties, experts and media?<br>
