The L.A. Times reports on a group claiming that the recent reduction in gas prices was caused by prayer. “If the whole country keeps on praying, we can bring down prices even more — to even less than $2,” says Rocky Twyman, founder of Pray at the Pump.
If prayer did cause the price to drop, did it do so through a shift in the demand curve or was it through a shift in the supply curve?
My sense is that the article is newsworthy because some people do not believe it is appropriate to pray for reduced prices. But praying for relief from crisis is a classic use of prayer. Georgia’s governor, for example, recently prayed for rain; some people believe that it worked.
Others do not believe prayer to be effective. But several studies have run randomized trials to determine whether prayer (or what is sometimes called “distance healing”) can be effective. For example, a small randomized study in a coronary care unit found:
The therapeutic effects of intercessory prayer (IP) to the Judeo-Christian God, one of the oldest forms of therapy, has had little attention in the medical literature. To evaluate the effects of IP in a coronary care unit (CCU) population, a prospective randomized double-blind protocol was followed. Over ten months, 393 patients admitted to the CCU were randomized, after signing informed consent, to an intercessory prayer group (192 patients) or to a control group (201 patients).
While hospitalized, the first group received IP by participating Christians praying outside the hospital; the control group did not. At entry, chi-square and stepwise logistic analysis revealed no statistical difference between the groups. After entry, all patients had follow-up for the remainder of the admission. The IP group subsequently had a significantly lower severity score based on the hospital course after entry (P< .01). Multivariant analysis separated the groups on the basis of the outcome variables (P<.0001). The control patients required ventilatory assistance, antibiotics, and diuretics more frequently than patients in the IP group. These data suggest that intercessory prayer to the Judeo-Christian God has a beneficial therapeutic effect in patients admitted to a CCU.
There is even a Cochrane Review of single-blind studies (where patients do not know whether others are praying for them). The results are mixed. But across six studies and more than 6,000 patients, there was a statistically significant reduced risk of death. (Good Bayesians are more likely to accept this result if it accords with their prior beliefs — and more likely to reject this result if it conflicts with their prior beliefs. Bad Bayesians who disagree will not even allow it to move their prior an iota.)
The idea of testing for the impact of prayer goes all the way back to 1883, when Francis Galton, the father of regression, sought to test the efficacy of prayer.
Some people have claimed that it is wrong to even try to empirically test the power of prayer. The Bible includes several passages admonishing us: “You shall not test the Lord thy God.”
But I also worry that this is a question that may not be fully resolvable by resorting to randomized study. If there is an omniscient God, then it is impossible to run a truly double-blind study. This creates the possibility for a transcendent kind of Hawthorne effect.
If God behaves differently in response to testing prayers than to non-testing prayers, then we will not learn whether non-testing prayers help (or hurt). On the other hand, if the null hypothesis is that prayer should have no impact, and we find one in patient-blind randomized control trials, then the atheists have some explaining to do.

But by letting oil prices get so high in the first place, does that indicate that God is on the side of Putin, Chavez and the mullahs in Iran and Saudi Arabia?
A God powerful enough to create the universe should have no trouble answering prayers, whether it be by supernatural action or in a way that is fully within the bounds of scientific law.
The answer to prayer is obviously not always yes, and even when we believe that the answer is yes; we must believe He answered yes by faith, because He leaves not a residue or trace.
In my opinion the greatest reason for faith derives not from the search for supernatural events, such as miraculous cures; but the miracle of the human soul – the infinite value of individual human life.
The effect of prayer has nothing to do with God or religion. It’s simply the power of the mind in action. Calling it “prayer” or “God’s Will” or whatever you wish is really just changing its name. Studies like this are only the tip of the iceberg in terms of proof that the power of the human mind is much stronger than we initially thought. It’s a shame that it’s been ridiculed as hoo-ha for so long and by so many (mainly due to the sad number of dishonest people that make so many false claims about it and try to exploit others). I long for the day when we’ll have enough scientific proof to warrant investing much more of our ressources into developping it. The cure for many currently uncurable disease might soon be within our reach.
I don’t want to open this can of worms, but I suppose someone has to do it: We’ve got to test which religion or christian denomination works best, in a fair, doubleblind controlled experiment. Then we would know who told truth and who was wrong. In fact, we should have done that BEFORE the various religious wars.
Or maybe not.
What is the mechanism through which prayer is expected to work? It seems like this is the question being asked in the comments in different ways. Has any work been done on this?
Or no shift in any curves – just a stronger dollar. Can you pray for that too?
While we’re at it, let’s go macro!
Let’s correlate the rise of Christianity through the centuries (and Judaism and Islam, too, why don’t we?) with the rates of disease, pestilence, natural disasters, and military successes in those regions. Let’s find out whose side God is really on!
I don’t have the time to find it right now, but there have been similar blind studies on praying for patients which have showed worse outcomes in the prayed for group. What have we learned from this? There’s a high degree of variability in outcomes for patients in the study.
The results aren’t reproducible. It’s as simple as that. Some studies can be well set up, and will still result in a great deal of noise, some indicating that prayer helps, some with the opposite results.
Additionally, it’s impossible to correct for people outside the study contributing their own prayers.
