ADHD and fluoride – wishful thinking supported by statistical manipulation?

Finding reality needs more than wishful thinking. The problem is that statistical arguments often provide a jargon to confirm biases. Image credit: Accurate Thinking Versus Wishful Thinking in Gambling I worry at the way some scientists use statistics to confirm … Continue reading

Fluoridation and ADHD: A new round of statistical straw clutching

“To clutch at straws – the act of reaching for a solution no matter how irrational or inconsequential.” Source: Advanced Vocabulary for English Language Learners Anti-fluoridation activists are promoting a number of new scientific papers they argue support their campaigns. But one … Continue reading

Fluoridation not associated with ADHD – a myth put to rest

The myth of community water fluoridation causing attention deficit hyperactivity disorder (ADHD) is just not supported by the data. I show this in a new paper accepted for publication in the British Dental Journal. This should remove any validity for … Continue reading

ADHD link to fluoridation claim undermined again

Recently I suggested that Attention Deficit Hyperactivity Disorder (ADHD) was better correlated with elevation than with community water fluoridation (see ADHD linked to elevation not fluoridation). I criticised the study of Malin and Till (2015) for limiting their investigation to a chemical toxicity … Continue reading

ADHD linked to elevation not fluoridation

Attention-Deficit Hyperactivity Disorder (ADHD) is more likely linked to residential altitude than community water fluoridation (CWF). This finding calls into question a recent paper claiming ADHD is linked to CWF. A paper that is being heavily promoted on social media at the moment … Continue reading

Data dredging, p-hacking and motivated discussion in anti-fluoride paper

Image credit: Quick Data Lessons: Data Dredging Oh dear – another scientific paper claiming evidence of toxic effects from fluoridation. But a critical look at the paper shows evidence of p-hacking, data dredging and motivated reasoning to derive their conclusions. And … Continue reading

Can we trust science?

Image credit: Museum collections as research data Studies based simply on statistically significant relationships found by mining data from large databases are a big problem in the scientific literature. Problematic because data mining, or worse data dredging, easily produces relationships … Continue reading

I don’t “believe” in science – and neither should you

I cringe every time I read an advocate of science asserting they “believe in science.” Yes, I know they may be responding to an assertion made by supporters of religion or pseudoscience. But “belief” is the wrong word because it … Continue reading

Hyping it up over fluoridation

In my time as a scientific researcher, honest scientists used to condemn colleagues who over-hyped their science. To our mind there should have been a special place in hell for scientists who misrepresented their findings or dishonestly described their significance. … Continue reading

Canadian studies confirm findings of Broadbent et al (2015) – fluoridation has no effect on child IQ

Readers may remember the scathing reaction of anti-fluoride campaigners to the paper of Broadbent et al (2015). This was the first paper to compare child and adult IQ levels for people living in fluoridated and unfluoridated areas. The anti-fluoride campaigners … Continue reading
