Scientific Investigations
While faith in the supernatural is not in itself usually considered to be the purview of science, claims of reproducible effects are nevertheless subject to scientific investigation.
A Cochrane review of intercessory prayer found conflicting evidence for claims of a positive effect, but there was a conclusion that "evidence presented so far is interesting enough to justify further study." A recent study not included in the review found that intercessory prayer had no effect on complication-free recovery from heart surgery, but curiously the group certain of receiving intercessory prayer experienced higher rates of complications.

Famous quotes containing the word scientific:
“The besetting sin of able men is impatience of contradiction and of criticism. Even those who do their best to resist the temptation, yield to it almost unconsciously and become the tools of toadies and flatterers. “Authorities,” “disciples,” and “schools” are the curse of science and do more to interfere with the work of the scientific spirit than all its enemies.”
—Thomas Henry Huxley (1825–95)
