Re. 4, not for the way I asked the question. Obviously asking for a probability, or any empirical evidence I would have to take your word on, would have been silly. But there might have been excellent public evidence against the Evil hypothesis I just wasn't aware of (I couldn't think of any likely candidates, but that might have been a failure of my imagination); in that case, you would likely be aware of such evidence, and would have a significant icentive to present it. It was a long shot.
