Nearly twenty studies of whether intercessory prayer has a positive (or any) effect on seriously ill patients have been conducted by physicians and other medical researchers since 1965. Results are mixed, ranging from mild positive effects to an increase in adverse effects. The assumptions of the very idea have been challenged—is prayer something that can be scientifically tested? Since it involves the existence of God, whose reality cannot be scientifically tested, does research of this type make any sense? In this episode, the PEERanormal panel discusses six scholarly articles on the subject: four actual studies, and two critiques of the enterprise and its assumptions:
