Six Hilarious Pseudoscience Contradictions


Pseudosciences are the imposters of real science. They attempt to mimic the activities and language used by scientists, but have no intellectual substance beneath their shallow surface. This is likely because science has such a strong cultural authority and has been responsible for many beneficial and exciting discoveries during the past few centuries. Anything that attempts to parasitize on science can potentially steal some of this authority from science.

Yet, because pseudosciences are not based on credible arguments or evidence, they contain a combination of wishful thinking and stuff that is plainly made up. Because critical thinking and scientific evidence plays very little role (in any), it is not surprising that inconsistencies and contradictions have crept into many forms of pseudoscience. These contradictions do not just occur between different kinds of pseudosciences, such as chiropractors claiming that giving birth is a massive trauma and that newborns must get spinal adjustments while natural birth activists think that giving birth in the wilderness is completely safe. They can also be found within a specific pseudoscience and that produces many great ironies that many quacks and cranks seem completely oblivious to. Let us look at six such hilarious pseudoscience contradictions. Read more of this post

Mailbag: But Some Scientists Disagree!!!11


It is time for another entry in the mailbag series where I answer feedback email from readers and others. If you want to send me a question, comment or any other kind of feedback, please do so using the contact info on the about page.

A common denialist tactic to spread fear, uncertainty and doubt about some scientific model or medical discovery is to attack the scientific mainstream explanation. This is typically done by either portraying scientists and doctors as evil, denigrate the scientific community as a whole or distract from the independently converging evidence by pointing to a few scientists that might disagree either with the entire model or some minor detail.

“Not all scientists agree!” is their call to arms, but they forget that there will always be disagreements in science. What they are effectively doing is either (1) radically exaggerating some internal scientific debate about some minor detail as if the entire scientific model was under threat or (2) artificially inflating the importance of a small number of scientists, researchers or doctors who disagree with the mainstream scientific model.

Why Postmodernist Glaciology is Pseudoscientific Bigotry

Postmodernist nonsense about glaciers

Are satellite measurements of climate parameters a masculinist attempt at fake objectivity that boils down to nothing other than pornography? Is glaciology just a form of “western science” that actively suppressing other ways of knowing because of its reliance on mathematical models and advanced technological equipment? Are glaciers offended when people cook with grease near them? Will fat turn into another glacier if left overnight? Is the world so chaotic and unpredictable that scientific investigation into glaciers is fundamentally impossible because of the supposed gendered nature of empirical research methods?

Sometimes you run across published papers that are so batshit that you cannot possibly fathom how they were published, passed peer-review or even funded. One such paper is the postmodernist piece “Glaciers, gender, and science” that was written by Mark Carey, M Jackson, Alessandro Antonello and Jaclyn Rushing and published in Progress in Human Geography in 2016. This post takes a closer look at this review paper with particular focus on its rampant abuse and misrepresentation of satellite measurements as a technique to monitor climate change.

Getting the role of ice in climate science wrong

The problems begin at the very start of the introduction. Here, Carey and colleagues (henceforth Carey et al.) charges into climate science and mischaracterize the role of ice and glaciers as means to understand and measure climate change:

Glaciers are icons of global climate change, with common representations stripping them of social and cultural contexts to portray ice as simplified climate change yardsticks and thermometers. In geophysicist Henry Pollack’s articulation, “Ice asks no questions, presents no arguments, reads no newspapers, listens to no debates. It is not burdened by ideology and carries no political baggage as it crosses the threshold from solid to liquid. It just melts” (Pollack, 2009: 114). This perspective appears consistently in public discourse, from media to the Intergovernmental Panel on Climate Change (IPCC).

This is, of course, completely untrue. Glaciers play a crucial role in climate science for a wealth of reasons. They offer a stunning visualization of the effects of warming that does not depend on mathematical models or political biases. If a glacier has been reduced by 40% over a certain period, then that is just a brute fact and no amount of political ideology or climate denialist misinformation can change that.

Water from glaciers also provide freshwater and electricity for many millions of people around the world and has important roles in agriculture. IPCC is aware of these issues and have entire rapports that focus on these very issues. One of the newest such reports is The IPCC Fifth Assessment Report from Working Group II called “Climate Change 2014: Impacts, Adaptation, and Vulnerability” that can be found here with a shorter summary for policymakers that can be found here.

Indeed, Carey goes on to mention some of these factors later in the introduction, but only as a means to knock down the straw man he has erected in the very first three sentences of the paper. This hows that the Carey paper has an ignorant view of the way glaciers are seen and used in climate science research. Read more of this post

Local Weather Still Not Global Climate

Temperature measurements

Climate change looks to be one of the major challenges facing humans in the 21th century and beyond. The evidence has accumulated to such an extent that we now can be reasonably confident that there is a current warming trend and that the human emission of greenhouse gases is a powerful contributing factor.

In fact, not only was April of 2016 the warmest April globally that has ever been recorded since measurements started, it is part of a 12-month streak of records. Yet, climate change denialism is alive and well.

There are thousands and thousands of newspaper articles, blog posts and social media groups that discuss global warming and climate change, yet people do not seem to be able to grasp the basic concepts of the field. One such prominent example is the difference between local weather and global climate. To put it simply, local weather is what you see outside the window, whereas global climate is long-term average trends for the entire world. NASA has a great article explaining the difference between weather and climate in additional detail.

Thus, it makes no sense to say that there is no global climate change because it was recently cold in some local area. Yet this is what climate change denialists and a lot of laypeople argue. In reality, it is as dumb as saying that there is no world hunger because you had a snack to eat last night or that because you no longer have a cold, infectious diseases must not be an issue globally.

Flawed Chemtrails Paper by Herndon Retracted

Retracted chemtrails paper

Chemtrails is a pseudoscientific conspiracy theory based on the notion that the government is secretly releasing mind-controlling chemicals that sterilize people from airplanes. In reality, it is a combination of water vapor and airplane exhausts. It is bad for the environment, but it is not even close to the fantasies put forward by conspiracy theorists. This is obvious from the realization that world population has increased from ~3 billion in the late 1950s to ~7 billion in the early 2010s, despite increased airplane traffic all over the world. In a similar fashion, the Flynn effect suggests that IQs are increasing by 3 points per decade. So the predictions made by the chemtrails conspiracy theory is refuted on all levels.

However, pseudoscientific cranks almost never let reality come in the way of a tantalizing conspiracy theory that appeal to their own biases and they make up increasingly bizarre and convoluted ideas as they go along. On 11th August 2015, the nuclear chemist J. Marvin Herndon got a paper that promoted chemtrails conspiracy theory published in an obscure journal called International Journal of Environmental Research and Public Health (2014 impact factor 2.063 according to their own website).

Swedish Far-Right Politician Talk Nonsense About Climate Change

letter to the editor by SD politician

The Sweden Democrats (SD) is a far-right populist and anti-immigration political party in Sweden. With its roots in Swedish Neo-Nazism of the late 1980s and early 1990s1, it has no resemblance to the Democratic Party in the United States. In fact, they are more similar to the British National Party and during the past 20 year it has tried to white-wash its image in various ways. In the last election (2014), they received almost 13% of votes and became the third largest party in Sweden. Recent opinion polls indicate that their numbers are rising. Many political commentators think that this is due to the recent election debacle, where neither the left or the right achieved majority and SD threatened to vote against any budget regardless of origin (and did so once) unless they were given strong influence on immigration. This led the other parties to create a cautious truce called the December Agreement, whereby they would not vote against the budget delivered by the largest coalition. Some voters considered this to be a betrayal and may have shifted allegiances to SD to voice their disagreement.

Recently, Josef Fransson (industry-political spokesperson of SD) and SD-supporter Sandra Palenryd (secretary at Halmstad Hylte) wrote an ignorant screed (webcite) against mainstream climate science and got it published as a letter to the editor in a local newspaper called Hallandsposten (“The Halland Post”). It regurgitates many of the same climate denialist assertions that have been refuted a thousand times before. It is noteworthy, however, that the official position of one of the largest political parties in Sweden is so deeply anti-scientific (they even go so far as to deny the existence of a current warming trend) and how this risks influencing public policy depending on the results of the next election. It would be a disaster if Sweden had its scientific research and reputation so easily undermined by unreasonable forces like SD. Thus, this merits a point-by-point refutation.

Mailbag: Eviscerating More Pseudoscientific Nonsense

mailbag letter

It is time for another entry into the mailbag series where I answer feedback email from readers and others. If you want to send me a question, comment or any other kind of feedback, please do so using the contact form on the about page.

It always amazes me that so many denialists continue to spew out the same old garbage over and over, despite the fact that it has been refuted thousands of times over. At the same time, they so arrogantly dismiss any criticism of their flawed understanding of science as unscientific. It has never been easier to selectively focus on information that only confirms your existing opinion. The Internet has created confirmation bias on steroids. This time, we are going to take on (1) a climate change denialist who deploys the global warming hiatus myth, (2) an anti-psychiatry proponent who tries (and fails) to refute the existence of schizophrenia with pure logic and (3) an anti-immigration proponent who promotes the “white genocide” conspiracy theory.

The global warming hiatus myth is based on cherry-picking intervals

Kevin King writes the following:

This article is cretinous in the extreme. The models tell us the global surface temperature will increase, as well as the ocean temperatures. For almost 20 years there has been no global warming, either on land or in the oceans that we can measure. Even a first year arts student could comprehend this. No you are the denialists and you all belong together in a mocked up moon landing studio somewhere out in the nevada desert with a bunch of creationists. Start using your brains and read some Richard Feynman. Because clearly you haven’t got a scientific bone in your body.

To illustrate how climate change denialists cherry-pick intervals to argue for the flawed notion of a global warming hiatus, consider the following graph:

escalator of doubt

Most denialists fixate at the starting point 1998. This is done because there was an especially powerful El Niño during that year, making the global temperatures quite high during that year in comparison with others. If you draw a trend line from 1998 to today, you can deceptively make it appear as if there has been no warming.

Is Donald Trump Scientifically Illiterate?

Donald Trump does not understand climate change

One of the most basic distinctions in climate science is the difference between weather and climate. Weather is the instantaneous atmospheric conditions, such as rainy, snowy, sunny and so on. Climate, on the other hand, is about long-term trends. Confusing weather with climate, claiming that we cannot predict climate because we cannot predict weather, or trying to argue against the existence of human-influenced climate change by referencing current weather events is one of the most common tactic used by climate change denier.

Trump fails on climate knowledge

Contrary to Trump, the existence of local anomalies does not refute a general trend. More about the difference of weather and climate can be found on the NASA website.

Donald Trump does not understand vaccines or the immune system

Trump claims to not be anti-vaccine, yet he pulls out a classic anti-vaccine trope:

Too many, too soon? Nope!

While the number of vaccines have increased over time, the number of immunological challenges (“antigens”) have decreased. This is because modern DNA technology has enabled researchers to include only those components that are necessary to produce a good response. In other words, vaccines poses a smaller challenge to the immune system now than it did in the past. For more information, see the Offit et al. (2002) paper in Pediatrics.
