Here we go agian

Just when we seem to be making progress over Syria this has to happen. The US was starting to accept that the current elected president in Syria no long “has to go.” Peace talks are underway in Geneva.

And then President Bashar al-Assad had to torpedo all this progress by launching a chemical attack on little children in Idlib. What a fool.Well, if you believe that I guess you might believe anything.

Well, if you believe that I guess you might believe anything.

In the video above, the former British Ambassador to Syria, Peter Ford, presents a far more sensible analysis. He is imminently reasonable in his analysis – but unfortunately the same cannot be said for our mainstream media, leading European politicians and the representatives of NATO countries in the UN Security Council.

Lessons from Aleppo reporting

I think it disgusting for our media and these politicians to unquestioningly take at face value reports from Al Qaeda – the umbrella organisation for the “rebel”/”terrorist’ groups in Idlib, and their propaganda arms – the White Helmets and the Idlib Media Center. Hell, we saw all this before. The propaganda from the Jihadists in east Aleppo, propagated by the White Helmets and the Aleppo Media Center. Reports of chemical attacks, massacres, bombing the “last” schools and hospitals.

In the end, the Aleppo Media Center and the White Helmets left with the jihadist fighters under the surrender agreement and have now set up in Idlib.

Now independent reporters have access to the parts of Aleppo formerly held by the jihadis what do we find? Schools used as arms factories, remaining evidence of the chemicals they used to manufacture chemical weapons.

And the jihadis have used, and still use, chemical weapons in both Syria and Iraq. Yet, strangely, those events, while they sometimes are reported in our mainstream media, never get the NATO Ambassadors running to call UN Security Council Meetings.

Of course, I do not know what really happened in Khan Sheikhoun, Idlib. We really don’t yet have the facts – as UN officials have pointed out. It seems to me unreasonable to assume that the Syrian air force used chemical weapons in their attack on jihadis there. After all, the Syrian government gave up all their weapons, under US supervision, in 2013. And what could they possibly have to gain? They are doling so well, militarily, at the moment. They don’t need this sort of bad publicity.

Dogs returning to their own vomit

No, the Syrian government is not gaining from this event – but the “rebels”/”terrorists” are. And so are those who wish to torpedo the peace conference – or worse, organise a NATO military attack on Syrian armed forces and aerodromes.

But haven’t we seen all this before. isn’t this what was attempted in 2013 with the blaming oaf a similar chemical attack on the Syrian government. Isn’t this, as Peter Ford says, just like “dogs returning to their own vomit.”

Hopefully, other politicians have a memory – and a conscience. They will not be fooled by yet another attempt to justify intervention. To justify “regime change.”

Hopefully, they will, at least, have more sense than the current gung-ho politicians from NATO. Hopefully, they will refuse to pass judgement until they have some facts. Hopefully, they will not be so silly that they trust the word of Al Qaeda and its propaganda arms.

The Putin Derangement Syndrome

Rolling Stone has come out with a name for a madness which seems to be sweeping the US  – and even more widely – at the moment. The Putin Derangement Syndrome.

The latest clinical evidence for this illness must surely be this report from the BBC on the deaths of 14 or more Russians in a Metro bombing in St Petersburg.  A report suggesting that somehow President Putin was responsible!

Such “reporting” is simply obscene. But in this world where the people with a Putin derangement syndrome seem to prevail such stupid allegation becomes evidence and then fact.

Will the St Petersburg bombing of 2017 be added to that already long list of Putin’s crimes? You know – the Moscow apartment bombings, the Moscow Metro bombings, the murders a Denis Voronenkov (murdered in  Kiev by a member of the neo-Fascist Azov brigade but blamed on Putin), Boris Nemtsov, Alexander Litvinenko, Boris Berezovsky, Paul Klebnikov, Anna Politkovskaya, etc., etc. All attributed to Putin, no evidence – but the simple allegations have become facts in the minds of this suffering from the Putin Derangement Syndrome.

Hell, it has apparently become necessary candidates for cabinet office in the US to give the politically correct answer to the questions – Do your believe Putin is a murderer? or Do you believe Putin is a war criminal?

Bugger the evidence – we just want to you come on board and show that you also suffer from the Putin Derangement Syndrome before we let you do this job.

And what about those who have died? Do we not wish to honour them? How does the Washington Times honour those people and their families by publishing (at least for a time) a photo of a protest in their report? As if the gathering was somehow celebrating the atrocity.

And in Germany, the government decided they wouldn’t taint the Brandenburg Gate with the Russian colours because the atrocity was not “exceptional.” Yet after similar attacks in Paris, Brussels, London, Istanbul , Nice and Jerusalem, the Berlin landmark was shown in solidarity with the victims in the national colors of the respective countries. After the massacre of an Islamic assassin in a gay club in Orlando in Florida with about 50 deaths last summer, the Brandenburg Gate was immersed in the rainbow colors of the gay movement.

In attacks in other countries, Berlin showed less selectivity. – Quelle: ©2017

OK, give the malady a clinical name. Call it the Putin Derangement Syndrome. Or perhaps, just be a bit more honest and call it old-fashioned racism (see Western racism and the stereotyping of Russians).

Whatever – I just find the attitude obscene.

Bottle fed infants: fluoridated water not a problem.

Parents need no longer be concerned about using fluoridated water for baby formula. Photo credit: Life insurance for your heirs

New recommended fluoride dietary intakes by infants and young children in Australia and New Zealand were recently published. The updated values are available online at Nutrient Reference Values for Australia and New Zealand.

This is a regular update – the Australian National Health and Medical research council advises these recommendations be reviewed every 5 years. But the new recommendations are interesting because the upper limit for fluoride intake for infants and young children is substantially higher than the previously recommended upper limit.

Public health policy in Australia and New Zealand aims to adjust fluoride intake at the population level to be high enough to prevent dental caries but low enough not to cause moderate or severe dental fluorosis or other adverse effects. But health professionals have noted an anomaly in recent years.  Dietary intake of fluoride by children may exceed the previously recommended upper levels – even when community water fluoridation levels are within the recommended targets. Despite this the occurrence of moderate or severe dental fluorosis in Australia and New Zealand was rare.

This led to health authorities acknowledging that, for example, bottle-fed infants may sometimes exceed the upper limits for dietary fluoride intake – but still recommending this was harmless. Anti-fluoride activists misrepresented this advice by claiming health authorities were recommending that fluoridated water not be used for preparing formula for bottle feeding. Their claims are incorrect and alarmist. The “warning” simply provided advice that there was no risk of harm but the if parents were concerned they should occasionally use non-fluoridated water to make up baby formula.

In part, this current report is a response to that conundrum.

Why the change?

Anti-fluoride propagandists will no doubt attack this change. They have made capital out of the situation in the past by claiming that infants and young children are getting dangerous levels of fluoride in their diet. They, of course, ignore or hide the fact that despite this, levels of moderate and severe dental fluorosis have not been a problem. They, also misrepresent the situation regarding dental fluorosis and its causes – see Dental fluorosis: badly misrepresented by FANNZ and Water fluoridation and dental fluorosis – debunking some myths.

However, the expert working group who reviewed the literature and came up with the new recommendations did have their reasons. And these were more than just the absence of moderate and severe dental fluorosis.

They also concluded the previous recommendation was not consistent. This is because it was based on the US Environmental Protection Agency’s use of mean dietary intake and not the higher percentile fluoride intake which should have been used for the upper limit.

Consequently, their recommendation for the upper limit of fluoride intake for children up to 8 years of age is 0.20 mg F/kg bw/day (kg bw = kg body weight). The previous limit was 0.1 F/kg/ bw/day. This produces the following upper limits for children of different ages.

In Australia and New Zealand, the estimated upper range of total daily fluoride intake for different age groups ranges from 0.09to 0.16 mg F/kg bw/day – considerably lower than the new recommended upper limit of 0.2 mg F/kg bw/day.


Will anti-fluoride campaigners top claiming that bottle-fed infants consume dangerous levels of fluoride if their formula is made with fluoridated water?

And the rest of us should not longer make the concession that intake levels are above the recommended upper limits – because they aren’t.

Another anti-fluoridation whopper

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. The attitude of voters was clear from a previous referendum which showed overwhelming support fo this safe and effective social health measure.Protests led to another referendum in October 21013 and again overwhelming support for community water fluoridation (CWF). A clear result and several months later the council reversed its stance –  we now have community water fluoridation again.

Yet anti-fluoride activists argued to reject the referendum result – so what is all the talk now about Patea and Waverly? Are they now objecting to a council which rejected the views of its electors?

Not at all. No referenda were held in Patea or Waverly. As far as I can tell there were no household surveys either. Simply the normal consultation process involving submissions. So where does Fluoride Free NZ (FFNZ) get its figures for the views of residents for the above poster? Are 85% of Patea and 75% of Waverly really opposed to CWF?

Again, no. Those figures represent the proportion of submissions presented to the council arguing against CWF. In fact, half of those submissions came from out of town – somewhere else in New Zealand or overseas. (Paul Connett, from the USA, and other members of his political activist group, the Fluoride Action Network, are regular submitters to New Zealand councils). This is typical of the way that these activists submerge councils with “submissions” when CWF is considered. Many submissions are simply copies or form letters.

By the same logic, FFNZ could argue that 75% of Hamiltonians were against fluoridation (because the overwhelming proportion of submissions to the council were). Despite the clear referenda results showing the opposite. In fact, FFNZ does list the submission number in the case of Hamilton as one of their referenda results!

Now we expect FFN to argue that over 90% of New Zealanders oppose fluoridation because that was the proprtion of anti-fluoride “submissions” to the recent selct committee hearings on the current fluoridation bill!

As they say – pull the other leg.

Wait – there is more!

But FFNZ goes even further over the top in their facebook presentation of this poster. They claim:


“In 2012 the South Taranaki District Council asked residents of Patea and Waverley if they would like fluoridation chemicals added to their water supply. The resounding answer was “NO”. However, Council went ahead and voted for it anyway. Because of the blatant disregard for the community’s wishes, New Health New Zealand took STDC to court. STDC have now spent $320,000 fighting this when they could have just backed off from fluoridation. This issue is going to go to Supreme Court some time in the future.
You have to wonder who these people are working for don’t you.”

So somehow the South Taranaki District High Council is to blame for the expenses involved in defending itself against court action – action taken by a lobby group of the New Zealand “natural”/alternative health industry. A big business worth billions that is pumping something like $100,000 a year into court actions agaisnt fluoridation. See Who is funding anti-fluoridation High Court action?Big business funding of anti-science propaganda on health and Anti-fluoridationists go to Supreme Court – who is paying for this?

How ridiculous – even for these political activists.

2018 Global Atheist Convention

Looks like we are going to have another regional global atheist convention.Such

Such conventions were held in Melbourne in 20110 and 2012 and were very successful. However, a lot has happened between prominent atheists since then. People have fallen out and personal campaigns have been promoted for and against personalities. I hope these conflicts do not jeopardise this planned convention.

I guess it will depend on the invited speakers. Salman Rushdie and Ayann Hirsi Ali will be interesting and attract lots of people. I look forward to announcements of other speakers in the planned line up.

So, I have my questions at the moment – but will certainly consider attending if the other speakers are as interesting.

Must renew my passport.

Meanwhile – if you are interested here is the message from the organisers:

The Atheist Foundation of Australia is pleased to announce the third Global Atheist Convention in Melbourne in February 2018.

Bringing together like-minded thinkers, and those who want to challenge their current thinking, the three-day exhilarating event will feature world-renowned speakers and entertainers.

Fluoridation: Making sense of the Ministry of Health data

Image credit: Built in Colorado

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 areas.

Well, the latest data (for 2015) has just been released and the anti-fluoridationist reaction is typical. They are presenting selected data to argue that “the gap [between the numbers of caries-free children in fluoridated and non-fluoridated areas] has become practically non-existent.”

And the make a big thing of comparing this “practically non-existent” gap with the 40% difference claim they attribute to the MoH. Needless to say, they are wrong.

Let’s have a look at what the 2105 data shows, how this compares with data from previous years and what the limitations of the data, and consequently any conclusions drawn from the data, are.

The data

The figures below show the data – I have included it in graphs showing the data for earlier years. Notice that the data is for Māori and “Other.” This is because the “Total” figures in the data tables throw all ethnic groups together and are therefore misleading. As I have pointed out several times in the past (Anti-fluoridation cherry-pickers at it again A challenge to anti-fluoridationers to justify their misrepresentation of New Zealand researchDebunking anti-fluoridationist’s remaining 12 reasons for opposing fluoridation and Schluter & Lee 2016 noted in their paper Water fluoridation and ethnic inequities in dental caries profiles of New Zealand children aged 5 and 12–13 years: analysis of national cross-sectional registry databases for the decade 2004–2013), Pacific island children, whose oral health is poorer than other groups, are concentrated in fluoridated areas of Auckland. This distorts the “Total” figures (in particular underestimating the oral health for fluoridated areas). Local anti-fluoride propagandists have taken advantage of this in the past to make untruthful claims.

The “Other” group will be mainly Pakeha, but also will contain some Asian. I have not included the data for Pacific island children – the relatively small number in non-fluoridated areas mean the comparison is rather erratic.

Data are presented for “% caries-free” – the proportion of children with no tooth decay, and mean dmft – the average number of decayed missing or filled tooth for each child.

5-year-old children

In summary, the reduction of dental decay (using % caries-free figures) for 5-year-old Māori varied between 8% and 60% in the years 2005 – 2015 and was 25% in 2015.

In summary, the reduction of dental decay (using % caries-free figures) for 5-year-old “Other” varied between 3% and 22% in the years 2005 – 2015 and was 3% in 2015.

Year 8 children

In summary, the reduction of dental decay (using % caries-free figures) for year 8 Māori varied between 12% and 48% in the years 2005 – 2015 and was 12% in 2015.

In summary, the reduction of dental decay (using % caries-free figures) for year 8 “Other” varied between 5% and 27% in the years 2005 – 2015 and was 5% in 2015.

Average effects

It’s worth looking at average effects out over several years to limit the effect of variability in the data. The is the result of the effect of fluoridation in reducing tooth decay (using % caries-free figures) – average effect in the period 2005 – 2015.

Average reduction of tooth decay: 2005 – 2015

  5-year-olds Year 8 children
Māori 33% 27%
“Other” 11% 15%

Problems with the data

Of course, this data is not meant to provide definitive measurements – it is simply the records for oral health (% caries-free and dmft) for different regions. There has been no determined effort to make sure that the resident regions of the child are the same as the school region. While there is some separation into ethnic groups there has been no effort to take into account factors like sex differences, socio-economic influences, dietary differences, and other dental treatment differences. For example, in some regions the health authorities have a programme of treating children in non-fluoridated areas with fluoride varnishes or taking extra steps to provide access to dentists.

It’s interesting that the anti-fluoride people prefer such data to more definitive data corrected for problems. Well, they do at the moment as they are cherry picking to support their claims (see MoH says Fluoridation reduces dental decay by 40% – No it doesn’t!). They are very critical of data from the MoH’s New Zealand Oral health Survey. The MoH acknowledged limitations inherent in this survey for determining an effect of fluoridation – and the anti-fluoride people love to quote that acknowledgment. But at least the Survey did give data:

“for people living in non-fluoridated areas, which are adjusted for age, sex, ethnic group and neighbourhood deprivation to allow appropriate comparisons with people living in fluoridated areas.”

Instead, the anti-fluoride people rely on cherry-picked comparisons from data where no such adjustments have been made. And they never acknowledge the limitations of that data.

Fluoride Free NZ cherry-picks data without correcting for ethnic differences, etc., to make their claim.

The “Halo Effect”

The graphs above do show a tendency for the fluoridated and non-fluoridated lines to approach each other. One could speculate on the reasons and more definitive studies are required to check out such speculation. But here are some of my ideas:

The results could be influenced by changes in residential vs school or dental clinic location. For example, the introduction of “hub and spoke” dental clinics during the 2000s may mean that more children now live in a region with different access to fluoridated water than that for the clinic or school. The recent provision of extra dental care, such as fluoride varnishes or more dentist visits in non-fluoridated areas, is also a likely possibility.

But another possibility is that the efficacy of community water fluoridation is declining – maybe because of better health care, diet, and parental responsibility. In fact, the evidence indicates that community water fluoridation may now have less importance in some cases than dietary intake from other food sources. This graph from a US Environmental Protection Agency report (Fluoride: Exposure and Relative Source Contribution Analysis) shows fluoridated water may now contribute less than 50% of the dietary intake for many children and certainly no more than 70%.

Percentage Media Contribution to Total Daily Fluoride Intake. Figure 7-1 in EPA report Fluoride: Exposure and Relative Source Contribution Analysis.

This has resulted in a “Halo effect.” Because processed foods and beverages now contain more fluoride than in the past (when non-fluoridated water may have been used in processing) the difference in total dietary fluoride intake between children living in fluoridated and non-fluoridated areas has been reduced. The common use of fluoridated toothpaste also contributes to this “Halo Effect.”

This does raise the question – if community water fluoridation is less important as a dietary source perhaps it could be stopped? Although the warning is that if community water fluoridation was stopped perhaps other dietary sources like processed foods and beverages would have a lower fluoride content and dietary intake would then fall below optimum levels.

It’s a complex issue.


Once again the local anti-fluoride activists have been caught out misrepresenting the MoH data by cherry-picking and purposely ignoring important factors like ethnicity.

Fluoride, coffee and activist confusion

Havana Coffee Works in Tory Street, Wellington. Great coffee and chance to see roasting in action. On the site of what was the old Wellington Milk Department in the 1950s.

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.This time I

This time I also set out to acquire some freshly-roasted coffee beans from one if the many roasters in Wellington.

The Havana roaster turned out to be a surprise. Not only are their coffee beans excellent ( I am looking forward to getting home and drinking coffee made with them) – they are based in Tory Street as the site of what used to be the old Milk Department. Some of you may still remember the days when milk was delivered to your house in the middle of the night by a milkman. My Dad was one of those milkmen, and my siblings and I all spent time helping him deliver milk in the dead of night. So that building brought back memories. Even got to walk along Channing street on the way back to my hotel. You wouldn’t know it now but that street was very disreputable in the 50s because of the opium dens in the old houses.

Select Committee Hearings

These were interesting. Submissions were called for on  Health (Fluoridation of Drinking Water) Amendment Bill currently before parliament. This legislation is not about fluoridation itself. It is about how decisions should be made – about the process, not the science. In effect, it proposes transferring decisions from local councils to District Health Boards.

Pressure for the law change came from local councils who were sick to death of the hounding from activists and being forced into making decisions – not about whether to fluoridate or not – but about the science. Activist submitters continued to deluge them with passionately-worded submissions full of scientific claims – councillors with no scientific skills were being forced into making decisions about the science – were the activists correct in their claims that fluoridation causes all the ills known to mankind or should they accept the science presented by the experts. After all, activist submissions could look very sciencey – they were often full of citations to the scientific literature!

True to form the anti-fluoride activists deluged the select committee with submissions which were irrelevant to the bill – very few of them actually suggested changes or showed any evidence they had read the bill. No, they did their usual trick of preaching about the “science” – their claims of harmful effects from fluoridation and that it does nothing for oral health anyway.

It is amazing to hear people make outrageous claims about the scientific literature – claims which make clear they have never bothered to read the source they are citing. I guess they think they can get away with such porkies and misrepresentations because they are talking to politicians. However, my impression was this failed at these hearings – unless submitters raised suggestions about the process they were simply politely thanked and sent away.

So I found it frustrating to hear such lies being peddled about the science (and discussion by the public was not allowed) but confident in the fact the select committee was just humouring these people. Responses from committee members were always about process – not the scientific claims.

My submission

There were only a few submissions which dealt properly with the wording of the bill – the vast majority were just empty anti-fluoride rhetoric. I made a submission as an individual scientist but also as part of the Making Sense of Fluoride (MSoF) team. It was great to catch up with MSoF people who I tend to talk with on-line every day but have not till now met in person.

This was my oral submission:

As Monty Python used to say: “And now for something completely different.”

I support this bill as far as it goes but don’t think it will solve the basic problems without changing the way the science is considered. I want to suggest a change.

The current submissions show the problem. This committee has been inundated with large numbers of written and oral submissions. Many of these are duplicates or form letters. Most are opposed to community water fluoridation and usually make scientific claims – such as fluoride is a neurotoxin, that it causes a high prevalence of dental fluorosis or uses contaminated chemicals.

Submissions often cite scientific articles – some have even attached copies of these articles. This sort of thing can impress the layperson – perhaps some of the members of this committee are impressed? After all, it is easy to fool the ordinary person with scientific claims, citations, documents and publications. Advertisers do it all the time.

But this committee is simply not considering the science. Political committees – parliamentary, local body or District Health Board should not make scientific decisions. They do not have the skills for this. Yet that is what most of these submissions are asking of this committee. It’s what was being asked of local councils and it will be what is asked of DHBs.

Consideration of the science behind community water fluoridation requires people with scientific and health skills. Such people need to check evidence provided, check citations when they are presented, check what the scientific literature actually says (which could be very different to what submitters claim). Proper scientific consideration requires that the claims and cited scientific literature need to be considered intelligently and critically. The wider literature needs to be consulted. Cited claims need following up.

I have attached a couple of documents that do this – these are responses to documents used by several submitter arguing against community water fluoridation.

The current wording this bill requires DHBs to consider the scientific evidence. That just invites opponents of community water fluoridation to inundate DHBs with the sort of submission this committee has received – and local councils have been inundated with. DHBs are no better equipped to deal with this than this committee or local councils.

I suggest a change requiring DHBs to take advice on the scientific evidence from central bodies – the Ministry of Health and the Public Health Advisory Committee. This would transfer responsibility for scientific considerations to central bodies better equipped to do that evaluation.

The Public Health Advisory Committee has a legislated role to consider questions like this and advise the Minister. It is also able to consult interested organisations, experts like the Royal Society and the Prime Minister’s Chief Scientific Advisor who performed the most recent fluoridation review. It can also consult appropriate individuals.

This would not remove the right of lay persons to make submissions about the science – it simply redirects those submissions to a more appropriate body.

I think a change like this should be welcomed by everybody. It removes from DHBs the impossible job of making decisions about the science they are not equipped to make. It provides a proper venue for the science to be considered intelligently and critically. It is a credible and authoritative body for scientific organisations, health organisations, activist groups and the ordinary person who has concerns on this issue – whether for or against community water fluoridation.

After all – if someone has a genuine concern or has evidence they think will stand up to scientific scrutiny why should they want to waste time submitting it to a committee of politicians? Wouldn’t they be far happier knowing they are appealing to people who have the skills to evaluate their concerns properly?

Trump didn’t invent the problems – and his opponents didn’t invent protest

Anti-Trump rally. Union Square, Manhattan, New York. November 2016. Image credit: Kelly Kline

At last, I find myself agreeing with something written by PZ Myers – well, sort of. I agree with the main message in his article about the current US political mess  – It is disturbing that the news is all Russia all the time – but it really does not go far enough. It doesn’t identify what actions should be pursued – nor does it identify the problems that have resulted in his main complaint.

Let’s get the fallacy in his first sentence out of the way. A fallacy which undermines the rest of his argument. Talking about the current political turmoil in the US he says: “I agree that the administration’s Russian connection ought to be pursued.” But he doesn’t say why.

The Russophobic diversion

The fact is Russia is a normal and natural country in the modern world. Its economy has strong international links and it is only natural that business and political personalities in the US will have, or will have had, links to Russian business, diplomats, and political personalities. Just as they have, and will have had, links to such entities from other countries, the UK, Germany, Saudi Arabia, Ukraine, Poland – and even little old New Zealand.

And that goes for US business and political personalities of all different political persuasions. Are US officials really going to get distracted by pursuing all these links, or even all the links with Russian entities? What about the international business links, including with Russia, of Democrat politicians – including the Clintons? What about the contact between Democrat politicians and Russian diplomats? Hell, should officials really investigate, and cast aspersions, on the many meetings ex-President Obama’s White House administration had with the Russian ambassador?

These links and contacts are perfectly natural in our modern global society – and they are only a current issue in the US because of the wave of neo-McCarthyism stalking that country. Neo-McCarthyism, we should remember, launched by Hillary Clinton to divert attention away from the political corruption in the Democratic Party revealed by Wikileaks. Neo-McCarthyism now maintained by Democrat politicians and anti-Trump elements of the intelligence community and mainstream media as a tool to control or limit the powers of the new administration.

Neo-McCarthyism is terribly dishonest and pernicious. It relies on Russophobia (which I often see as a form of racism – the last respectable form see Western racism and the stereotyping of Russians) and, in the end, the fear of being outed as a traitor, to bring people’s thinking “into line.”

And PZ Myers has fallen completely into that trap with this acceptance of neo-McCarthyism in his first sentence.

The real problems – and they aren’t new

But Myers goes on:

“but I am not happy that that is being treated as the primary reason to delegitimize Donald Trump. The man is a destructive incompetent with a fist full of bad policies, and the most effective way to bring him down is to expose the fact that his campaign staff talked to the Russian ambassador? What? Have you looked at what he is doing to the country right now? Because there is a whole lot of crap going down while we’re busy looking for Russians under the bed.”

Myers should be unhappy that such neo-McCarthyist reasons are used at all – from the point of view of democratic and human rights. But, yes, he makes a valid point – the neo-McCarthysim is a diversion. People should be paying attention to the real problems the US election result has left them with – a President and, probably more importantly, a Congress where anti-science and anti-human rights elements have been strengthened.

PZ illustrates this by listing some of the proposed cuts to the EPA budget. Others will find similar regressive proposed action in other areas. But PZ Myers is all at sea when it comes to fighting these problems:

“There is no single reason to rise up and throw these assholes out — they’ve provided an embarrassment of causes that make them terrible leaders, which is part of the problem, that the reasons for taking action have been diffused so widely. It seems to me that our targeting is off when conversations with Russian diplomats become the strongest reason for investigating the president, rather than his habit of appointing incompetents and looters like DeVos and Pruitt to run major government agencies.”

It is politically immature to see the solution as “to rise up and throw these assholes out.” Come off it. The president was legally elected. It is childish for the defeated parties to see “rising up and throwing out” elected leaders as a solution. Such advice, while it may appeal to the more emotional and immature, is a recipe for continued defeat, not a solution.

The fight-back is not new either

These problems upsetting people did not suddenly appear with the election of a new president. They have been there for a long time – as has the struggle against them. The election results did not create the problems – it simply made them worse.

Democratic and humanitarian-minded people (and science-minded people) have been fighting these problems for years. The fight against racism, environmental pollution, climate change denial and limitations on the reproductive and other rights of women is not new.

The fight-back uses many methods – lobbying and representation to Congressional committees, publicity in the mass media and alternative media,. petitions, citizen’s meetings. participation in political parties, rallies, and demonstrations.

No, the current rallies and demonstrations are not new. But, I am amazed that some people who have joined these, donned knitted pink hats and vented their feelings at anti-Trump rallies think they have invented something new. Perhaps the only new thing in their political activity has been the lack of clearly defined purpose. (And perhaps it is this focus on Trump himself which has made them susceptible to the ne0-McCarthist argument – to the extent they will often use it in their slogans).

Where have these people been? And that is a valid question as there is a school of thought that some of the current protesters had, in the past,  been lulled into inactivity, a false sense of contentment because they believed “their” democratic president was handling the situation. Solving all the problems. Stopping US interventions and war mongering overseas.

While it is true that Trump’s election may have encouraged some people to become active and to join the fight back, let’s not pretend the fight-back is at all new or that these newcomers have invented it. If anything, their lack of specific targets and resort to personal expression of their own anger is a bad sign, not a good one.

Because the fight back on all these important issues is not new and has developed its own maturity it will not disappear when the current highly motivated and emotional responses subside. Hopefully, many of the people who have joined the fight back because of their response to the presidential election result will stay and participate in the long-term struggles.

It would be nice to think that PZ Myers would get past his current emotional concept of the fight-back – “rising up and throwing out the assholes.” That he might actually participate in the day to day struggle of people fighting against the anti-democratic, anti-women, racist and anti-science policies.

Unfortunately, if his current habit of attacking people involved in these struggles because they do not measure up to his standards continue, this will not be the case.

Anti-fluoride authors indulge in data manipulation and statistical porkies

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 people are fooled by the use of those magical words – “statistically significant.”

I suppose the lay person could be excused – although it would pay even them to be a bit more sceptical about such claims. But it seems that even some “scientific” journals, or perhaps inadequate peer reviewers, can be fooled by those magical words. Here is an example in the paper by Hirzy et al., (2015) in the journal Fluoride. (Yes, I know, this journal is well known for its anti-fluoride stance and poor scientific quality but I would have thought the editor, Bruce Spittle,  would have picked this one up – even if they do not have an adequate peer review system. Perhaps the fact Spittle is one of the authors of the paper is a factor).

I critiqued the paper in my article Debunking a “classic” fluoride-IQ paper by leading anti-fluoride propagandists and have submitted a more formal critique to the journal (see – Critique of a risk analysis aimed at establishing a safe dose of fluoride for children.) But here I just want to deal with those magical words used in the paper – “statistically significant.”

Hirzy et al (2016) rely completely on data reported by Xiang et al., (2003) and claim they “found a statistically significant negative relationship between . . . .  drinking water fluoride levels and IQ.” Trouble is – you can search through the data presented by Xiang et al., (2003) and there is absolutely nothing to indicate a “statistically significant” relationship. Sure, that paper actually claims “This study found a significant inverse concentration-response relationship between the fluoride level in drinking water and the IQ of children.”  But there is no table or graphic presenting the individual data points and no statistical analysis for drinking water F and IQ. Rather surprising because Xiang et al., (2003) did present the individual data points for urinary fluoride and did present some results for statistical analysis of other relationships.

The trick behind the misleading use of Xiang’s data

However, what Xiang et al (2003) did do was separate their drinking water fluoride and IQ data into different ranges. This is a table of their result.

While group F was data for one village (Xinhuai) and the data in the other groups were for a separate village (Wamiao), there was no explanation of the criteria used for the groups – and the numbers in each group very tremendously. Over half the children (290 of the total 512) were in Group F and the size of the other groups seem to arbitrarily vary between 8 and 111.

This manipulation produces data which can be used to imply a statistically significant relationship. Do the statistical analysis for water F and IQ in the above table and sure you get a lovely straight line, a correlation of 0.96 and very significant statistically (p=0.003). But because of the manipulation, this says exactly nothing about the original data.

I will illustrate this by taking some data which Xiang et al (2003) did provide – for urinary fluoride and IQ. The data are illustrated in the figure below from the paper.

A statistical analysis of that data did show it was statistically significant – Xiang et al. (2003) cite a “Pearson correlation coefficient –0.174 , p = 0.003.” Now, that explains about 3% of the variance in IQ and I would have liked to see a similar analysis for water F as other workers have usually found weaker relationships for water F than for urinary F.

But let’s try using the manipulation of Xiang et al (2o03) and Hirzy et al (2016) to make the relationship between urinary F and IQ look a lot better than it is. I used a software tool to extract data from the figure – it didn’t extract all the points (264 out of a total 290) because of overlaps but statistical analysis of my extracted data gave a Pearson correlation coefficient of 0.16, p=0.010. Very similar to that reported by Xiang et al., (2003).

The tricky manipulations

I have absolutely no idea why Xiang et al., (2003) used different group sizes – so, to be fair, I have divided my extracted data into 6 groups of 44 pairs each (after sorting them into order based on urinary F) to produce the following table.

Urinary F IQ
A 1.79 105.57
B 2.30 89.45
C 2.30 77.72
D 2.69 68.58
E 2.48 56.25
F 2.69 40.10

This produces a lovely graph:

But, just a minute, I can get a better graph if I sort  the data according to IQ instead of urinary F:

But why stop there. If I choose different group sizes – remember Xiang et al., (2003) had groups ranging from 8 to 250 in size – I am sure I can get an even better presentation of the data.

TBut these graphs look far better than the one presented in Xiang et al (2003) for urinary F. We have taken data where the urinary F data explains only about 3% of the variance in IQ and produced graphics implying it “explains” up to about 75% of the variance. And we could “explain” more with a bit of extrra manipulation.


Data manipulation like this doesn’t change the fact that while the relationship between urinary F and IQ is statistically significant it only explains about 3% of the variance in IQ. This means that other factors, or confounders, should be considered – and when they are it is likely the significant relationship of IQ to urinary F would disappear.

Although Xiang et al., (2003) did not provide any statistical analysis to support their claim there was a significant relationship between water F and IQ I am sure the relationship is similar to that for urinary F – maybe even worse. Manipulating the data by using a range of groups of different sizes has certainly made the data look a lot better – but it is completely misleading.

I think it shocking that the authors of the Hirzy et al., (2016) paper have used manipulated data in this way – first to claim that fluoride in drinking water has a major negative effect on IQ and secondly to use such massaged data to work out a “safe dose.”

Worse, the journal Fluoride, and its peer reviewers, should never have accepted this paper without querying the claim of a significant relationship between drinking water F and IQ.
