Study tests the power of prayer and finds it could make matters worse
Published: 01 April 2006

"We are praying for you ... you will be in my prayers." In this
ostentatiously religious country, such phrases drop routinely from the
lips of presidents, politicians and ordinary people when wishing
someone well before an operation. But do prayers make any difference?
If a major scientific study here is to be believed, the answer is, no.
Indeed, if a patient knows there is organised prayer on his or her
behalf, such intercession might actually make matters worse.
