The authors of a recent paper inform us that Reiki is a Japanese system of energy healing that has been used for over 2 500 years. It involves the transfer of energy from the practitioner to the receiver, which promotes healing, and can be done by either contact or non-contact methods. Both the receiver and the practitioner may feel the energy in various forms (warmth, cold, tingling, vibration, pulsations and/or floating sensations). Reiki can also be self-administered if one is a Reiki practitioner. Reiki is mainly used to address stress, anxiety, and pain reduction while also promoting a sense of well-being and improving quality of life.
Such statements should make us weary: what is presented here as fact is nothing more than conjecture – and very, very implausible conjecture too. Anyone who writes stuff like this in the introduction of a scientific paper is, in my view, unlikely to be objective and could be well on the way to present some nasty piece of pseudo-science.
But I am, of course, pre-judging the issue; let’s have a quick look at the article itself.
The purpose of this study was to determine the effects of a 20-week structured self-Reiki program on stress reduction and relaxation in college students. Students were recruited from Stockton University and sessions were conducted in the privacy of their residence. Twenty students completed the entire study consisting of 20 weeks of self-Reiki done twice weekly. Each participant completed a Reiki Baseline Credibility Scale, a Reiki Expectancy Scale, and a Perceived Stress Scale (PSS) after acceptance into the study. The PSS was completed every four weeks once the interventions were initiated. A global assessment questionnaire was completed at the end of the study. Logs summarizing the outcome of each session were submitted at the end of the study.
With the exception of three participants, participants believed that Reiki is a credible technique for reducing stress levels. Except for two participants, participants agreed that Reiki would be effective in reducing stress levels. All participants experienced stress within the month prior to completing the initial PSS. There was a significant reduction in stress levels from pre-study to post-study. There was a correlation between self-rating of improvement and final PSS scores. With one exception, stress levels at 20 weeks did not return to pre-study stress levels.
The authors concluded that this study supports the hypothesis that the calming effect of Reiki may be achieved through the use of self-Reiki.
QED – my suspicions were fully confirmed. This study shows precisely nothing, and it certainly does not support any hypothesis regarding Reiki.
If we recruited 20 volunteers who were sufficiently gullible to believe that watching an ice-cube slowly melting in the kitchen sink, or anything else that we can think of, has profound effects on their vital energy, or chi, or karma, or anything else, we would almost certaily generate similar results.
My conclusion is therefore very different from those of the original authors: THIS STUDY SUPPORTS THE HYPOTHESIS THAT GULLIBLE PEOPLE CAN BE EASILY MISLEAD ABOUT BOGUS THERAPIES WITH PSEUDO-SCIENTIFIC STUDIES BY IRRESPONSIBLE WOULD-BE SCIENTISTS.
