Comment Re:Never underestimate psychosomatic effect of bel (Score 1) 304
I have heard a suggestion that they had some sort of poison that reacts differently when someone is anxious vs calm. Think of it like a polygraph test with potential physical consequences. It could well have had better than chance odds of affecting the guilty (anxious) more than the innocent (calm). And no doubt the priests could have helped with that, by telling them "don't worry, God knows" and all the ceremony. Of course, this is all speculation as no one knows exactly what the stuff was. And being "better than chance" isn't even saying much.
