Imagine a very simple poll that asks your yes/no opinion on a single issue. Say the question is "do you think sales tax should be raised by 2%?"
In addition to the "yes / no" check boxes, the ballot designers decided it might be useful to also ask the question "on a scale of 1-10, how strongly do you feel about this issue?"
When it comes to tablulation, should the responses to the second question be taken into account, or should they be ignored?
>From a purely utilitarian point of view (i.e. "greatest happiness"), it makes a lot of sense to give more weight to the opinions of those who feel more strongly. But common sense tells us why this is a bad idea. Intentionally ignoring this information (or, more likely, not collecting it in the first place) is the only thing that makes sense....otherwise people who had any opinion whatsover would have an incentive to vote insincerely, saying they felt very strongly so as to have the most impact on the outcome.
I believe that condorcet elections intentionally ignore "strength of opinion" information for the exact same practical reason. Since there is no way to avoid collecting some strength of oopinion information (while still collecting the information we *do* need), we have to consciously, intentionally ignore that information in the tabulation. This is NOT a bad thing.
BTW, I think this is also relevant to range voting, which from my point of view is flawed for the same reason.
