Why is it so difficult to get an open discussion on fluoridation? - Open Parachute

Ken Perrott Mar 22, 2018

Yes, I know – everyone’s mind is already made up so participants just talk past each other. People’s positions on this and similar issues have become a matter of identity – people are driven by emotions, not information. But, the information is there – and while I agree many people are driven by emotions they often attempt to use that information to … Read More

Ken Perrott Mar 13, 2018

My recent article Paul Connett’s misrepresentation of maternal F exposure study debunked got some online feedback and criticism from anti-fluoride activists. Mary Byrne, National coordinator Fluoride Free New Zealand, wrote a response and requested it is published on SciBlogs “in the interests of putting the record straight and providing balance.” I welcome her response and have posted it here. Hopefully, this will … Read More

Paul Connett’s misrepresentation of maternal F exposure study debunked - Open Parachute

Ken Perrott Mar 06, 2018

Anti-fluoride campaigners are misrepresenting a recent Mexican study claiming its findings should cause governments around the world to abandon community water fluoridation (CWF). Their claims are unwarranted because the study has a high degree of uncertainty. Activists are misrepresenting the accuracy of the studies findings. Because Mexico has areas of endemic fluorosis the study itself is not relevant to CWF. Read More

Opinion: Anti-fluoride activist commits “Death by PowerPoint” - Open Parachute

Ken Perrott Feb 28, 2018

We have all sat through boring, and counterproductive, PowerPoint presentations. Boring because the presenter breaks all the rule relevant to the preparation of visual displays. And counterproductive because, in the end, the audience does not remember any of the information the presenter attempts to convey. David JP Phillips gives some relevant advice on PowerPoint preparation in the video … Read More

Paul Connett “updates” NZ MPs about fluoride - Open Parachute

Ken Perrott Feb 22, 2018

 Data from Bashash et al., (2017). Despite a statistically significant relationship of child IQ with mothers prenatal urinary fluoride, this explains only about 3% of the huge scatter in the data. I haven’t followed the latest speaking tour of Paul Connett – organised by the local Fluoride Free NZ organisation. But I watched a TV interview with him this … Read More

Yet another fluoride-IQ study - Open Parachute

Ken Perrott Jan 31, 2018

As with most of these fluoride-IQ studies this one is only relevant to areas of endemic fluorosis (This is from a UNESCO paper and has been corrected for New Zealand. Identification of fluorosis in a country does not imply the whole country is high fluoride). Yes, it’s a bit like groundhog day. Another fluoride-IQ study – and we expect this to … Read More

Science Tank | Fluoride - Guest Work

Guest Author Jan 08, 2018

Conspiratorial people love to claim that the government adds fluoride to water and toothpaste in some dastardly plan to make us all sleepy slaves, helpless to resist their evil bidding. The truth, however, is far less scandalous and far more reassuring – fluoride is your friend, my friend, and geochemistry is how we know this! Teeth are comprised of … Read More
