Professionals in modern psychology, behavioral medicine, and psychoneuroimmunology are exploring ways in which we can "mentally" influence our own bodies through hypnosis, imagery, visualization, attention, intention, and other forms of self-regulation--for fostering physical and psychological health and well-being.
The author does a fine job of identifying rigorous studies that have been designed to demonstrate the effects of distant mental influence while controlling for possible confounding factors. Some of the studies go back several years but most were well-designed and do tend to document that something non-local is happening. The findings of most of the studies, although contrary to our common conceptions of what effect an individual can have on another individual at a distance, point to an ability that goes beyond what we can currently explain based on existing theories of cause and effect.
