Jon Stewart had a hilarious piece last night about a new medical study showing that prayer has no power to influence outcomes of heart surgery. The long and short of it is not only that prayer turns out to be ineffective as an influencer, but that the surgery itself is more problematic than its marketing makes it seem: in both of the groups that were prayed for, more than between 50and 60% developed complications after the surgery. As Stewart says, "maybe what we need is better heart surgeons." Stewart went on to show President Bush saying he was sustained by the thought that so many people were praying for him. "So that's what went wrong," said Stewart.
