Where is the data? That's the question the other side has to answer, not just assert. The best controlled test of intercessory prayer, the STEP study in American Heart Journal, found no measurable benefit, and that's one reason anecdotal accounts don't move me. I'm not saying absence of evidence is absolute proof of absence. But on a claim this large, the burden sits with the affirmative side. Poll numbers show belief is common, not that it's true. When my opponent offers personal experience, I'll ask for controls, replication, and effect sizes.
