There is a movement in the US to oppose a public health measure that is backed by impressive evidence showing it is safe and effective, as well as highly cost effective. For as long as the government has supported this health measure, there have been those opposed to it, claiming (against the evidence) that it is unsafe, ineffective, and represents a violation of personal freedom and the right to refuse an unwanted medical intervention. I could be talking about vaccines and the anti-vaccine movement, but in this case I am talking about the fluoridation of public water supplies and the antifluoridation movement.
This social debate (there isn’t much of a scientific debate) crops up in the news every now and then – mostly prompted by an antifluoridation activist or group making noise, or by a local referendum to block fluoridation in a community. Recently there has been a Harvard study making the rounds of social media, Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis. The actual findings of the study do not show that there is any risk to public water fluoridation (if anything, they show that it is safe), but the study was seized upon by antifluoridation activists and distorted for their propaganda purposes. Unfortunately, the internet is now fertile ground for the spreading of propaganda.
The NYS Coalition Opposed to Fluoridation put out a press release distorting the findings of the study. Their press release (“Harvard Study Finds Fluoride Lowers IQ – Published in Federal Gov’t Journal”) was then printed as a science news item by many online news outlets. Reprinting press releases, without any editorial filter, is a cheap and easy way to add news-like content to your website. The Sacramento Bee, for example, published the press release under their “News” tab. Near the top of the page, in small print, they did put a disclaimer (which is better than most sites):
This section contains unedited press releases distributed by PR Newswire. These releases reflect the views of the issuing entity and are not reviewed or edited by the Sacramento Bee staff. More information on PR Newswire can be found on their web site.
That’s better than nothing, but I wonder how many people reading the press release will notice and read the disclaimer. In my opinion, a news outlet should not reprint press releases sent out from advocacy organizations clearly intended to promote an agenda. They especially should not print them under the banner of “News.” The disclaimer is not adequate. The spreading of this “news item” around Facebook and other social media demonstrates this.
