Citing scientific studies and the arrogance of ignorance

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

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

No, fluoridation is not associated with leading causes of death

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

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

March ’17 – NZ blogs sitemeter ranking

Ken Perrott Apr 01, 2017

Here are the rankings of New Zealand blogs with publicly available statistics for March 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 There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters.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 people … Read More

Another anti-fluoridation whopper

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

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)

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
