In recent weeks, we've reported here on new studies from Australia and New Zealand that strongly suggest ailments attributed to wind turbine sound are actually caused by the "nocebo" (similar to placebo) effect, in which individuals who are led to expect physical symptoms experience those symptoms, whether or not the supposed cause of the symptoms is actually present.
This week's news stories have included two related items, one illuminating and the other less so.
First, the New Yorker blog has an excellent discussion of nocebo, titled "The Nocebo Effect: How We Worry Ourselves Sick," that mentions wind turbine sound only briefly and focuses instead on other activities that have resulted in similar concerns, such as wireless communications. It notes, for example, "After the 1995 Aum Shinrikyo sarin nerve-gas attack in Tokyo … hospitals were flooded with patients suffering from the highly publicized potential symptoms, like nausea and dizziness, but who had not, it turned out, been exposed to the sarin. This is common in disasters where the agent is invisible, as with chemicals or radiation."
The article also summarizes a famous case in which a single teacher at a high school complained of a "gasoline-like" smell and dizziness, whereupon more than 100 other teachers and students fell ill–and no cause for the ailments was found. Describing other experiments in which nocebo effects have been found, the article says that they "… [draw] a direct line between irresponsible journalism and health problems."
"Irresponsible journalism" brings us to the second item of note, a segment by National Public Radio (NPR) that highlighted the findings of Dr. Nina Pierpont, a New York pediatrician who coined the phrase "Wind Turbine Syndrome" to describe symptoms reported to her by neighbors of wind projects. Dr. Pierpont's work has been strongly criticized for its lack of basic scientific procedures and safeguards, as Media Matters for America, a media watchdog group, explains in a blog post on the NPR piece:
"Pierpont's report consisted of telephone interviews with 23 people who responded to an ad asking for people who claimed to experience 'wind turbine syndrome,' and their anecdotes about 15 family members.
"The Chief Medical Officer of Health of Ontario, Canada, stated in a report that 'no conclusions on the health impact of wind turbines can be drawn from Pierpont's work due to methodological limitations including small sample size, lack of exposure data, lack of controls and selection bias.'" [emphasis added]
NPR also implied that a recent scientific review finding that hair cells in the ear may react to inaudible low-frequency sound provides support for Dr. Pierpont's thesis. Media Matters, however, correctly noted that this finding is not new and that there is no evidence that the reaction of these cells affects the functioning of the inner ear. Low-frequency sound, it added, is very commonly found in both natural and human environments. The NPR report, it concluded, " … is the kind of 'irresponsible journalism' that the New Yorker noted can exacerbate the 'nocebo effect.'"
