The reason we don't throw out the interventions for colon cancer is because they have been shown empirically to mitigate morbidity and mortality. We know that outcomes are better with them than without them however many don't benefit. That's how we decide when an intervention produces a better outcome than a placebo - in controlled, randomized, double-blind studies.when we treat colon cancer, there is an 80% success rates which means that 20% are not successful. We celebrate the success and realize or study why the 20% didn’t make it. We certainly don’t throw out the treatment because there were failures.
You probably already know the outcome when prayer was tested against no prayer:
From Study of the Therapeutic Effects of Intercessory Prayer (STEP) in cardiac bypass patients: a multicenter randomized trial of uncertainty and certainty of receiving intercessory prayer - PubMed
"Conclusions: Intercessory prayer itself had no effect on complication-free recovery from CABG [coronary artery bypass grafting], but certainty of receiving intercessory prayer was associated with a higher incidence of complications."
The STEP study revealed no benefit to prayer, but worse, demonstrated a deleterious effect of being a cardiac patient and a believer going for relatively dangerous surgery and knowing that you were prayed for.
Of course you did. The scientific community disagrees with you, but it evaluates evidence differently than a believer with a confirmation bias would.I found those studies to be filled with flaws.
