Boosting the immune system – sorting science from myth

This article has been updated and republished to clear up some points, and add another section. The comments for this article are closed, please comment at the new article.

One of the most ridiculous pseudoscientific claims that I keep hearing from the junk medicine crowd is that this supplement or that food is critical to boosting the immune system – it’s so prevalent that I believe I read it several times a day.

These type of claims ignore one basic physiological fact: the immune system is a complex interconnected network of organs, cells, and molecules that prevents invasion of the body by hundreds of thousands, if not millions of pathogens every day. And no matter how much individuals try to trivialize how complicated the immune system is by claiming that downing a few tablets of echinacea will boost the immune system to prevent colds (it doesn’t), it doesn’t make it science.

And it isn’t that simple.

The bad science checklist of GMO opponents

One of my favorite science websites is at Science or Not, the author of which, Graham Coghill, claims that “this website will help you separate real science from nonsense that’s masquerading as science.” Most real scientific skeptics have that goal, but Coghill does a great job in formalizing science into a readable, logical format.

Coghill has been doing a couple of series of blog posts, both of which are some of my favorites for science. One is the “Hallmarks of Science,” which endeavors to describe what makes good science.

Then there is its evil twin, the “Red Flags of Science,” which points out the indicators of bad science, pseudoscience or plain nonsense.

So with all due respect to Graham Coghill, I’m going to abscond with his Red Flags of Science series, and show how the GMO opponents use bad science to make their case. (Please note, I deleted some Red Flags that didn’t apply to GMO refusers, like magical powers).

Antivaccine cult resorts to ad hominem attacks

I get a lot of email about this blog. Most of it is nice, many asking questions or recommending future topics. I do enjoy the recommendations, because it sometimes leads to some interesting areas of research.

Occasionally, I get critical emails, some civil, and some not quite as civil. And I got one of those emails, with interesting and not very creative ad hominem attacks – really could some of you do better than this?

Logical fallacies – debunking pseudoscience

Logical fallacies are essentially errors of reasoning in making an argument – identifying them is an excellent tool in debunking pseudoscience and other junk science. When logically fallacious arguments are used, usually based on bad reasoning to support a position (or to try to convince someone to adopt the same position), it is considered a fallacy.

Most of you didn’t know, because I didn’t promote it much, but I had a link in the menu for a list of logical fallacies. It lay fallow, barely read by me or, apparently, anyone else.

However, I decided to update and improve my list of favorite logical fallacies used by all of the pseudoscience crowd. There are many more logical fallacies than what I list, but this blog is focused on providing evidence, in a snarky way, against anti-science claims made by everyone from the vaccine deniers to creationists.Read More »Logical fallacies – debunking pseudoscience

The zombie anti-vaccine lie–Peter Doshi and the appeal to authority

flulaval-flu-vaccine

Updated 4 November 2014 to add some ironic analysis of Doshi’s “not-an-epidemiologist” background.

A few  months ago, I wrote an article about Peter Doshi, a Ph.D. who is doing some postdoctoral work at Johns Hopkins University, one of the leading institutions of higher learning in the USA. Doshi is truly not very notable in science, except last year, he wrote an article about flu vaccines, basically employing the Nirvana Fallacy that because flu vaccines aren’t 100% effective they are worthless. Since vaccines are fundamentally a medical procedure to mitigate risk with a very low risk of adverse events, even 50% effectiveness will save thousands of lives. But we’ll get back to that.

The article he wrote is not actually based on real research, but appears to be an opinion paper–kind of like the opinion papers written by creationists who want to convince anyone who will listen that dinosaurs lived with humans. Doshi denies that most flu’s are even caused by the influenza virus. I guess the CDC’s high tech diagnostic tests for influenza are all wrong. But then again Doshi presents no evidence.

Because of the zombie myths of the antivaccination world, myths or papers that are reanimated every few months because the vaccine denier community actually lacks any fresh evidence to support their nonsense. So Doshi’s paper from 2013 is resurrected in the antivaccination press. A few days ago, an obscure pseudoscience promoting website started banging the drum about Doshi’s comments. The article, found in the Realfarmacy website, has this scary headline: “Johns Hopkins Scientist Reveals Shocking Report on Flu Vaccines.” Makes it sound like Doshi wrote another article. Which he didn’t.Read More »The zombie anti-vaccine lie–Peter Doshi and the appeal to authority

The anti-GMO bad science checklist

gmo-grenadeThis article is a substantial update of the original one published last year. 

One of my favorite science websites is at Science or Not, the author of which, Graham Coghill, claims that “this website will help you separate real science from nonsense that’s masquerading as science.” Most real scientific skeptics have that goal, but Coghill does a great job in formalizing science into a readable, logical format. If I had to only read one science blog, it would be his, since his logical methodology to critically evaluate scientific claims would help me evaluate anything I read.

Coghill has two ongoing series of articles, one, the “Hallmarks of Science,” which endeavors to describe what makes good science, and it’s evil twin, the “Red Flags of Science,” which establishes the key indicators of bad science, pseudoscience or plain nonsense. With these two powerful tools, one could, through an openminded analysis, determine the the strength of evidence supporting a claim.

Vaccine deniers use logical fallacies to prove superiority

The natural immunity fallacy.
The natural immunity fallacy.

I frequently employ the term Logical Fallacy to demonstrate a logical or rational failure of a particular argument, especially those who adhere to anti-science or even pseudoscience points of view, like antivaccinationists. Logical fallacies are used to win arguments, despite the merits of said argument.  It’s also used to divert the reader (or listener) to a totally irrelevant point, but has the illusion of being logical.  

There are several definitions of what constitutes a logical fallacy:

A logical fallacy is, roughly speaking, an error of reasoning. When someone adopts a position, or tries to persuade someone else to adopt a position, based on a bad piece of reasoning, they commit a fallacy.–Logical Fallacies

An argument that sometimes fools human reasoning, but is not logically valid.–Fallacious Argument

In logic and rhetoric, a fallacy is usually an improper argumentation in reasoning resulting in a misconception or presumption. By accident or design, fallacies may exploit emotional triggers in the listener or interlocutor (appeal to emotion), or take advantage of social relationships between people (e.g. argument from authority). Fallacious arguments are often structured using rhetorical patterns that obscure any logical argument.–Wikipedia

Generally, in discussions or debates, those who lack scientific evidence (which is based on the logical scientific method), have only one choice–resort to one of many logical fallacies. Over time, distinct types of logical fallacies that help define a failure of a pseudoscientific argument. Let’s look at one that is popular with the antivaccination crowd.

Opinion: why vaccine denialism is so annoying

SwineFluVaccineI’m writing this opinion piece not for those who vaccinate themselves or their children, because they accept the science either because they reviewed it and accepted it, or they just know that vaccines work and are relatively safe.

On the other hand, this article is not written for the antivaccinationists, because they don’t listen to logic anyways. They ignore real science to invent their own, based on lies, pseudoscience, and logical fallacies.

No, this article is written for those who may be on the fence about vaccines, and thinks there’s some sort of balanced discussion or debate about vaccines. It’s time to dispel the false-balance discussion pushed by pseudoscience for the simple reason because they lack the intellectual and scientific evidence.

Let’s look at how the antivaccinationists have gone off the rails of real scientific understanding.Read More »Opinion: why vaccine denialism is so annoying

The Zombie Apocalypse of antivaccine lies–they just won’t die

zombies-vaccinatedThose lies from individuals who push pseudoscience can be likened to zombies. The lies seems to arise out of unscientific, ignorant, and brainless nonsense. The lies keep arising even after scientific skeptics bury them. Of course, the lies are so loud, it really sounds like the groans of the living dead. Oh, and we can’t forget that the goal of these lies is to eat the brains of the innocent people who are trying to understand the real facts about vaccines. Of all of the pseudoscience zombies out there, the vaccine deniers are the worst, because people die from the zombies, much like what happens from vaccine preventable diseases.

There is a particularly annoying and obnoxious vaccine-denying zombie liar who goes by the handle of The PatriotNurse. Now, as you would expect from her name, she is a nurse, but she runs with the anti-government, conspiracy theory loving, pro-gun (and I don’t mean just owning one gun, but having a full armory because of the government and conspiracies) crowd. And she is antivaccination, as you may have guessed. She posted a crazy video on YouTube, which lists out all of the canards and lies of the antivaccine zombies.  

Amusingly, she has disabled comments to this video by stating, “The comments are OFF for many reasons. Foremost is that I refuse to be abused for a contrarian viewpoint that goes against mainstream “Sickcare.” One of the fun things about YouTube is the comments section, where you can cheer for a good music video, or attack someone who posts dumb stuff. But The PatriotNurse refuses to allow her zombie ideas to be shown in the bright light of the day. After watching some of her other videos, I cannot believe someone actually gave her a degree in nursing.

In her vaccine denying, anti-science video, The PatriotNurse uses the standard repertoire of unsupported claims, myths and fairytales that most antivaccinationists use to make their ignorant cases. So, in order of the stupidity of her zombified argument, let me try to chop of its head, and hope the argument doesn’t come back again. Maybe I’m naive about that.Read More »The Zombie Apocalypse of antivaccine lies–they just won’t die

Identifying science denialism and pseudoscience

Science denialism, a form of pseudoscience, is everywhere these days. There’s the oft-discussed vaccination denialists who refuse to vaccinate children because they believe that vaccines cause some condition (usually autism), and Big Pharma hides evidence. Or AIDS denialists who believe that HIV doesn’t cause AIDS. Or global warming deniers who think that either global warming isn’t happening or, if it is, it’s not caused by human activities. Or evolution denialists, like Ken Ham, who think that one hundred years of scientific research can be ignored for a book that was written 5000 years ago to help illiterate pastoral farmers understand the natural world. It’s not just science, of course, there are Holocaust deniers, who think that no Jews were killed by the Nazis. There are even 9/11 deniers (usually called truthers) who think that Big Government (probably in league with Big Pharma) is hiding the truth about what really happened on 9/11.Read More »Identifying science denialism and pseudoscience
