MH17 tragedy – new investigation launched

Ken Perrott Jun 09, 2016

Two years after the shooting down of the Malaysian commercial airliner (flight MH17) over eastern Ukraine (Donbass), investigators seem no closer to identifying the culprits. This may seem surprising given the quick recovery of the black boxes and most of the airplane. But, on second thoughts, perhaps not surprising given the regional … Read More

Fluoridation debate: Responding to Tom O’Connor

Ken Perrott Jun 02, 2016

Ken Perrott responds to Tom O’Connor’s post Debating fluoridation and tyranny – Tom O’Connor responds. This is the second article in the debate. I think Tom’s concept of “freedom of choice” is confused. He appears to be arguing for his own right to determine a social decision. But that is undemocratic, it imposes an individual’s wish on society. Read More

May ’16 – NZ blogs sitemeter ranking

Ken Perrott Jun 01, 2016

There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters.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 wanting their own blog included. I encourage and am happy to respond to queries … Read More

Debating fluoridation and tyranny – Tom O’Connor responds

Ken Perrott May 31, 2016

Individual consent – what does it mean and how is it obtained? This article below is a guest contribution from Tom O’Connor responding to my article on attempting a tyranny of the minority on fluoridation. I invited Tom to discuss the issue here, and offered him a right of reply because I think there is value in discussing the points he … Read More


Water fluoridation: attempting a ‘tyranny of the minority’

Ken Perrott May 29, 2016

Tom O’Connor, president of Grey Power, describes community water fluoridation (CWF) as the “Tyranny of the Majority” (see “Fluoridation of water a trampling of our right,” Timaru Courier, May 26th). Well, it is nice to see an anti-fluoridation piece which does not resort to scientific misrepresentations and distortions.* These fallacious “scientific” arguments a really just a proxy … Read More

Public discussion of science can be toxic

Ken Perrott May 19, 2016

Public discussion of the science around problems humanity faces today seems inevitably to be diverted by hostility, misleading propaganda, personal attacks, and even outright censorship* of scientists and supporters of science. This creates an atmosphere, and an information overload, which turns the ordinary person off –  if it doesn’t actually fool them into taking up an unscientific position. So … Read More

Overall increase in tooth decay noted in fluoridation cessation studies

Ken Perrott May 15, 2016

Anti-fluoride activists love to trot out studies where no increase in tooth decay was found after community water fluoridation  (CWF) ceased. They are cherry-picking, of course, because they ignore the studies which do show a decline in dental health. I have written about this before (What happens when fluoridation is stopped? and Anti-fluoridationist’s flawed attacks on Calgary study), so I am pleased to see a … Read More

Don’t be fooled by simple media “science”

Ken Perrott May 11, 2016

This video is getting plenty of coverage – and despite its length, it is worth watching. The humour helps, of course. You certainly won’t be bored if you commit the 20 minutes required to watch the video right through. Oliver warns about the way journalists often misrepresent the science. Further, he is warning that often the science itself is suspect … Read More
