[EM] Re: CIBR examples, and its CC failure

Hello Ken,

Nice ideas. Correlation seems like a useful tool that could be applied 
also elsewhere than with Borda. It sure is more natural (and wider) 
than the normal clone definitions (unfortunately not as simple but of 
course so are peoples' opinions).

Borda has some problems with strategic voting (e.g. burying the worst 
competitor at the end of the list). But also voting methods that are 
intended for honest men (that you mentioned) are interesting and useful 
too.

Since I mentioned the usefulness of honest men dependent "sincere" 
methods I'll give also one example. Strategic voting related defensive 
requirements could be relaxed when a group of experts vote on what 
shares to buy with their joint money. All want to take the benefit of 
each others' expertise (and have no interest in pushing their own 
(maybe limited) viewpoints through). In this case (more "sincerity 
dependent") voting methods like Borda or sum of ratings may be the best 
choice.

Eliminating looped votes (A>B>C, B>C>A, C>A>B) is a very different 
thing (and more problematic) to me than eliminating reverse votes 
(A>B>C, C>B>A).
