You're saying a jury will reach the wrong verdict more than 50% of the time, and a bench will reach the right verdict more than 50% of the time? I don't disagree, but are there statistics?
That's not necessary. If we assume that both juries and judges pick the correct verdict with a certain probability independent of what the correct verdict is, then all that is required that the jury has a higher probability of being wrong than the judge.
Yep, makes sense. So is there some kind of data to back up the claim that a jury is wrong more often? Perhaps verdicts are more likely to be overturned for juries?
