What's weird to me is that people actually seem to be weighing factors for and against, as if they'd believe Titor was a time traveller if only his predictions would seem to add up well enough. Of course the whole concept is ludicrous and self-contradictory. If I had stated in November that I have clairvoyant powers and that there would be a great lamentation coming in Southeast Asia, would it suddenly seem likely that I can see you gasping with awe in front of your monitors?
