I wonder if you could do something like a blind auction. In effect, your winning probability is assigned based only on agreement. For example, Randomly pair up the voters with a randomly assigned compromise. Each voter offers to switch pair for a compromise that is better than current pair This causes a reassignment of the pairs The process is repeated until stable This means that a voter doesn't have to say who is their favourite. Ofc, offers near the start would likely use their favourite as compromise and slowly backtrack if it isn't accepted. ---- Election-Methods mailing list - see http://electorama.com/em for list info
