I'll be more specific. Suppose that there are three candidates A, B, and C , of which your favorite is A, and that there are five voters. You ask the other four ahead of time what their utilities for the three candidates are. They trust that Cranor's method is strategy proof, so they frankly

I doubt the method is non-monotonic; the counting is done by Approval. The reason you got the A answer the first time is that you fed the other voters' information into the simulation of the election. The strategizer in the real election only improves your vote over the simulated election if the

It seems pretty clear that at some point you have to make a trade-off between electing the candidate with the highest SU, and ensuring that your method has low strategy. However, its unclear at what point you have to start making a trade off - it is conceivable that there are methods out

I understand the question and it does seem paradoxical. Since I don't know the details about the method I can only speculate. Imagine that each voter is given a computer which is running a standard piece of software that implements a standard strategy algorithm. The software takes a voter's

This is more of a query about Lori Cranor's method than anything else. If it really gives no strategic incentive for distorting ratings, it sounds like the ideal way to use CR ballots. Here's what puzzles me. On the one hand, it seems like any method like Ms Cranor's that uses CR ballots to
