I think it is difficult to define a sincere vote as something completely isolated from its effects on the outcome, since I think that those effects are what give votes "meaning"
True, but with ranked methods, I think we can pretty easily define "sincere" to mean that you ranked them according to your actual preferences. Likewise under plurality, if I preferred Ralph Nader to Al Gore (in 2000), but voted for Gore because I thought Nader didn't have a chance, and preferred Gore to Bush... that's an insincere, strategic vote.
One shortcut to deciding what is a sincere vote is if you actually would vote the same way if you truly had no idea which of the candidates is more likely to win. If so, that is (in all cases I can think of) a sincere vote.
