You only "get" what you selectively want to get. The point is made perfectly that the experiment is tried on a very controlled and repeatable process in medicine that has a equally expected complication rate. I know you are not stupid, so the concept of the survival rate, and complication rate, decade to decade has improved, an as medical break throughs came, so did those improvements. Your study in terms of a monitoring of results, prooves that medicine, like manufacturing products, strives to "Control the process". That process is repeated, and the same techniques and practices, make the rate of complications predictable, and limited to 51-52%.
Now the question is how was prayer affective during the entire evolution of heart or other medical proceedures, that prayers led to new discoveries, new technology, etc. etc. I could stand next to Niagara Falls with a million people praying for the water to stop, but the results are pretty predictiable arn't they? It isn't much of an experiment when the results are so predictable, the effect would not be measureable.
How do you know that prayers did not led to some genius inventing the artifical heart? That prayers did not enlighten researchers to deeper and more productive thoughts and processes? You re entitled to your opinion, but this study is not conclusive of a thing. What were the complications, and were serious life threatening complications give the same weight as a minor complication that was routine? Nothing is charcterized about the severity of complications. Nothing was characterized as to the prayers themselves, where they were done, how, as a group, individually, in a church, while driving down the highway, or just going to the bathroom. The study is not very specific. On the other hand, what infomation was given as to the total healing time of those who did not have complications? Were they all a sucess, how many died, and was the total average time of healing improved from decadses ago?
I get what the study was completly, and with all due respect, what athiest would believe figures that showed a measurable result of imporvment based on prayers? Maybe everyone prayed for everyone to do their best, and it worked because the compications were all consistant with expected results.
