Activist confusion at fluoridation bill hearing (and coffee)

Ken Perrott Mar 24, 2017

I have been in Wellington for the Parliamentary select committee hearings on fluoridation. Well, that was the excuse – I was really there to catch up with my family (always a joy and am amazed at how tall my grandson has become) and to enjoy the great food in Wellington cafes. Havana Coffee Works in Tory Street, Wellington. Great coffee … Read More

Anti-fluoride authors indulge in data manipulation and statistical porkies

Ken Perrott Mar 12, 2017

Darrell Huff & Irving Geis wrote a classic book – How to Lie With Statistics. They outline various ways data can be presented to give the wrong story. However, there is an even more naive use of statistics to misrepresent data – just declare that a relationship is statistically significant, don’t show any data or statistical analysis. Unfortunately, many … Read More

EPA comprehensively debunks anti-fluoride claims of a fluoride-IQ effect

Ken Perrott Feb 26, 2017

The US environmental Protection Agency (EPA) has denied an anti-fluoride petition to ban community water fluoridation. The document outlining its reasons for declining the petition is valuable because it considers all the arguments and evidence presented in the petition and comprehensively shows them to be misleading or even false. This is a humiliating defeat for the petitioners – the US  Fluoride Action … Read More

Anti-fluoridationists go to Supreme Court – who is paying for this?

Ken Perrott Feb 22, 2017

The costly battle to prevent fluoridating the water supply of two small Taranaki towns has gone on for four years – and it looks like continuing. Last October the South Taranaki District Council won a costly four-year court battle for the right to fluoridate the water supplies of Patea and Waverley. New Health NZ, which took High Court action to … Read More

Debunking a “classic” fluoride-IQ paper by leading anti-fluoride propagandists

Ken Perrott Feb 21, 2017

Three of the paper’s authors – Quanyong Xiang (1st Left), Paul Connett (2nd Left) and Bill Hirzy (far right) – preparing to bother the EPA. Anti-fluoride groups and “natural”/alternative health groups and websites are currently promoting a new paper by several leading anti-fluoride propagandists. For two reasons: It’s about fluoride and IQ. The anti-fluoride movement recently decided to give priority to this issue … Read More

Islamophobia or mental illness?

Ken Perrott Feb 16, 2017

Mental illness is far more widespread than we often wish to admit. In fact, it is probably worth considering it a normal part of life – like the occasional cold or other ailments we all get. But occasionally mental illness can be more debilitating – even embarrassing. Does any family not have a member who sometimes embarrasses them by behaving inappropriately? … Read More

Non-fluoridated Christchurch does not have better teeth than fluoridated Auckland

Ken Perrott Feb 07, 2017

It seems every time anti-fluoride propagandists present data it is either cherry-picked, distorted or misleading. Often all three. So it is hardly a surprise to find local anti-fluoride propagandists are telling porkies again. They have been promoting this graphic claiming it shows people in “non-fluoridated Christchurch have “better teeth.” But the graphic is based on naive cherry-picking of the data, it ignores the effect different ethnic … Read More

January ’17 – NZ blogs sitemeter ranking

Ken Perrott Feb 01, 2017

Here are the rankings of New Zealand blogs with publicly available statistics for January 2017. There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters. (Let me know if I weed out yours by mistake or get your stats wrong). Every month I get queries from … Read More

Debunking anti-fluoridationist’s remaining 12 reasons for opposing fluoridation

Ken Perrott Jan 31, 2017

New Zealand anti-fluoride campaigners have whittled their list of objections to community water fluoridation (CWF) down to 12 reasons. Maybe that’s progress – they used to tout a list of 50 reasons! Let’s go through that list one by one and see if any stand up. I am responding here to each reason given in the Fluoride Free New Zealand’s … Read More
