“The flaws in this study are numerous. The number of subjects is too small, there is no control group and it isn’t blinded. The study reveals that some of the children are on medication but it does not take into account the possibility of recent changes in medical therapy, or improved compliance while on the study. It is based purely on self-report and subjective questionairres and there is very high liklihood that a placebo effect could have been the sole responsible factor in the subjects’ apparent improvements. The authors then call for larger and better designed studies, something which I don’t think is justified for these reasons, but my problem with this study, and concerns regarding the credulous take by the media, go much deeper than what I’ve already explained.
What led me to dig deeper after reading the Reuters’ report was the following quote:
“The effect was much greater than we expected,” lead researcher Sarina J. Grosswald, a cognitive learning specialist in Arlington, Virginia, said in a written statement.”
I wondered why the researcher had expected an effect and hypothesized that there may be a connection between the researchers and TM more significant than academic curiosity. I was quickly able to discover that Grosswald is a hardcore believer in TM. Just read this quote by Grosswald from a website called Ask The Doctors
, which provides a forum for specialists to answer questions related to TM and health
“The TM technique is the exact opposite of harmful. It reduces your risk of getting serious chronic health problems like hypertension, diabetes, and heart disease. In fact, research on the Transcendental Meditation program shows that people who practice it go to the doctor about 50% less than the general population. And if they are in the hospital for some reason, their hospital stay is 50% shorter, on average. For some conditions, the need for medical care is as much as 87% less for TM meditators. Practicing the Transcendental Meditation technique is one of the best things you can do for your health.”
She clearly does not come across as an unbiased investigator. In reading her other responses on the “Ask The Doctors” website, and especially after listening to a 16-minute talk
she gave in 2005, when this research actually took place, which is posted on a Maharishi Vedic Education Development Corporation sponsored website that focuses on “ADHD, the Mind and the Transcendental Meditation technique” called Insights in Health
, it is obvious that she is a true believer. That doesn’t prove the research is bogus by itself, but it is a red flag.
A more concerning red flag, and one which was also discovered in the talk given by Grosswald, is the fact that the 10 children involved in the study may have been coached. In the last few minutes of the presentation, Grosswald presents clips of the children meeting with the TM proponents prior to the initiation of the study, where it appears that they are told what the expected outcome of the trial is, that their symptoms will improve with TM. “
“It wasn’t difficult to look at this study and see that the claims being made by TM supporters aren’t valid. It wasn’t even that hard to uncover the connections between the investigators, the school where the study was conducted and pro-TM organizations. Yet I was unable to find one news report that displayed even the slightest amount of critical thinking, instead reading like press releases from TM believers. The current state of science and health reporting is rather depressing, and I don’t see things improving any time soon as more and more dedicated science writers are falling prey to the poor economy.”
