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

An open letter to Paul Connet and the anti-fluoride movement

Paul Connett and Vyvyan Howard have, through the local Fluoride Free New Zealand activist group, published an open letter addressed to NZ scientists and educators (see An Open Letter To NZ Scientists And Educators). It is strange to encourage scientific … 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
