Misrepresenting fluoride science – an open letter to Paul Connett

A new year and a new speaking tour of New Zealand by US anti-fluoride campaigner Paul Connett. Looking over the presentation he is giving at his New Zealand meetings I find he has absolutely nothing new to say. It’s all been … Continue reading

Alternative reality of anti-fluoride “science”

Paul Connett made many unsupported claims in his presentation against community water fluoridation (CWF) to Denver Water. Here I debunk a claim where he rejects most scientific studies on the cost-effectiveness of CWF. Connett asserted two things in his presentation: … Continue reading

Wishart misrepresents fluoride science to advance his extreme ideology

Seems if there is an anti-scientific bandwagon to climb on New Zealand’s own self-described “investigative journalist” just can’t help himself. Having self-published books on climate change (he denies the science) and evolution (he supports creationism) it shouldn’t be long before he … Continue reading

Peer review, shonky journals and misrepresenting fluoride science

Occasionally groups with an anti-science message will get hold of a ‘peer reviewed’ paper in a scientific journal which fits their message completely. They will promote it heavily as scientific ‘proof” for their message. This is currently happening with a paper published … Continue reading

Repeating bad science on fluoride

Anti-fluoride propagandists have been trumpetting a new “peer reviewed” scientific paper in their campaign against fluoride. Most of them don’t seem to realise that the claim is not new – just a re-presentation of claims from a paper they already … Continue reading

Anti-fluoride activists attempt to silence science

Roger Stratford, a local aspiring politician, wants scientist to shut up. He is campaigning against the fluoridation of Hamilton’s water supply (we have a referendum coming up) and is a member of Fluoride Free Hamilton. He is also campaigning for … 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

Embarrassing knock-back of second draft review of possible cognitive health effects of fluoride

This is rather embarrassing for a US group attempting to get the science right about possible toxic effects of fluoride. It’s also embarrassing for the anti-fluoride activists who have “jumped the gun” and been citing the group’s draft review as … Continue reading

The promotion of weak statistical relationships in science

Image credit: Correlation, Causation, and Their Impact on AB Testing Correlation is never evidence for causation – but, unfortunately, many scientific articles imply that it is. While paying lip service to the correlation-causation mantra, some (possibly many) authors end up arguing … 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
