The page http://stackoverflow.com/privileges/view-vote-counts (and the corresponding page on the other SE sites) includes the following question and answer:
When should I view vote counts?
Statistically speaking, the vast majority of votes cast are upvotes. (Remember that downvoting costs a small amount of reputation and requires more reputation to earn as a privilege).
That doesn't seem to answer the question at all. Either the question or the answer should be changed so that the latter answers the former.
