This study speaks volumes, but in an unusual way:

Co-author Radin is perhaps best known for an earlier study:
“Effects of Intentionally Enhanced Chocolate on Mood,” Dean Radin, Gail Hayssen and James Walsh, Explore, vol. 3, no. 5, September 2007,pp. 485-492. (Thanks to Mary Beckman for bringing this to our attention.) The authors, at the Institute of Noetic Sciences and at Hawaiian Vintage Chocolate in Honolulu, Hawaii, explain:
“A double-blind, randomized, placebo-controlled experiment investigated whether chocolate exposed to “good intentions” would enhance mood more than unexposed chocolate…. The intention in each case was that people who ate the chocolate would experience an enhanced sense of energy, vigor, and wellbeing…. Each person consumed a half ounce of dark chocolate twice a day at prescribed times. Three groups blindly received chocolate that had been intentionally treated by three different techniques. The intention in each case was that people who ate the chocolate would experience an enhanced sense of energy, vigor, and well-being. The fourth group blindly received untreated chocolate as a placebo control….
“Conclusion: The mood-elevating properties of chocolate can be enhanced with intention.”
