When it comes to large scale voting systems, I actually think that because of the Public Good nature of intelligent voting, voters are likely to vote with prosocial intent but also irrationally (they want the government to be good for people in general, but they favor stupid methods for doing that; see this). Thus the major problem large scale voting systems have is not the design of the voting system but with poor decision making on the part of voters. I actually have a proposal for taking advantage of prosocial voting but encouraging more intelligent voting decisions (link). I do not claim it is likely to ever get enacted.
