Citing scientific studies and the arrogance of ignorance - Open Parachute

Ken Perrott Apr 27, 2017

One thing that gets me going (as readers here probably know) is the way scientific citations are cherry-picked and dragged in to support biased positions. It’s a common form of confirmation bias in the fluoridation debate. And I get even angrier when the perpetrators cherry-picking citations will then claim they “have science on their side.” Parroting citations and (often unconnected) claims … Read More

Debating science - Open Parachute

Ken Perrott Apr 25, 2017

This last week has certainly raised the profile of the “science debate” in New Zealand. Most importantly we saw big turnouts for the Science March in several major cities – a demonstration that lots of scientists and supporters of science feel that science could be threatened – or at least that it is unappreciated by the politicians and other decision-makers. Maybe … Read More

An open letter on fluoride, science and kindness - Nano Girl

Michelle Dickinson Apr 17, 2017

Dear Lorraine, I see that last week you decided to send this message to Green Party MP Julie Anne Genter: After reading your e-mail I decided to create a flowchart for you to follow for the next time that you decide to interact with another human being.  This should especially be used when communicating with people that you … Read More

No, fluoridation is not associated with leading causes of death - Open Parachute

Ken Perrott Apr 16, 2017

We are all going to die but fluoridation isn’t killing us. Oh, dear – the local anti-fluoridation people are at it again. More cases of fiddling statistics  – and yet again the guilty party is the US anti-fluoridation activist Karen Favazza Spencer. She should really take some advice about statistics. Although I suspect she doesn’t care – she is just … Read More

Anti-fluoridationists exploit infant deaths by fiddling statistics - Open Parachute

Ken Perrott Apr 09, 2017

The local anti-fluoride people have not stopped rabbiting away with their “science” – searching for anything bad they can argue is caused by community water fluoridation. The latest claim they make – fluoridation is responsible for infant deaths! And they have some statistics to “prove” this. The table below presented by well-known US anti-fluoride activist, Karen Favazza Spencer, in … Read More

Another anti-fluoridation whopper - Open Parachute

Ken Perrott Mar 31, 2017

We are all used to political activists fiddling statistics – but this has gone too far. Local anti-fluoride activists are so narcissistic they are now presenting their own clamouring as representing public opinion – even putting figures to it. I find this really offensive. As a Hamiltonian, I objected to the undemocratic put our council took in stopping fluoridation in 2013. Read More

Fluoridation: Making sense of the Ministry of Health data - Open Parachute

Ken Perrott Mar 28, 2017

Every year local anti-fluoride activists eagerly await release of the latest Ministry of Health (MoH) data on the oral health of New Zealand School children. These data are a mine of examples which can be cherry-picked to argue that community water fluoridation is ineffective – or even that the oral health of children in non-fluoridated areas is better than fluoridated … Read More

Activist confusion at fluoridation bill hearing (and coffee) - Open Parachute

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 - Open Parachute

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 - Unsorted

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
