Second, when your guide, Gary Posner, makes a claim that there's no evidence that the group didn't pray for itself, upon what evidence does he make that claim? None. I can claim that you're a Northeastern liberal, but upon what evidence do I base this? None. Just like Posner. Secondarily, he seems fixated on the idea that quantity of prayer=effectivity. Upon what simplistic vision does he base this? Have you asked yourself these questions, or just swallowed it whole? It is up to the person performing the experiment to exclude interferring factors, or at least account for them. The study failed to do so.
Third, the exact experiment has not been repeated, that is true. But then, nobody's resurrected the Studebaker either. The Studebaker was produced and reproduced multiple times.
Fourth, which are the "numerous" studies that you would like to bring to the table that refute Byrd? Did they utilize the exact same criteria that Byrd did, or did they attempt to proof his study with different methodology. Name the study and let's see. You have already stated in a previous post that Byrd has its contradictions. No need to follow this line.
Posner, Flamm, and no study names. Hmmm....
