It’s difficult to be a real scientific skeptic – let’s make it easier

scientific skeptic

Since I started this website, nearly four years ago (that’s 50 internet years), I’ve noticed a serious problem – some skeptics, even scientific skeptics, are lazy, trying to take the easiest way to accept or refute a claim. It is difficult to be a real scientific skeptic (see Note 1). It’s not impossible, but it takes more than using some intentional or unintentional bias or fallacy.

This lack of real skepticism has manifested itself in some incredible meta memes: “vaccines are dangerous,” “gluten is dangerous,” and “GMOs are dangerous,” even in groups who are ostensibly “pro-science.” However, if I replied to them, “wow, you must be a creationist too,” generally, their indignant reply would make a sailor blush.

Scientific skepticism is hard, not because of the complex science (even though, that is part of the issue), it’s because searching for the evidence that supports or refutes some claim is often nuanced, and contradictory. And researching it isn’t easy.

Thus, as a self-proclaimed scientific skeptic, I thought I’d write an article to help anyone learn more about what interests them, how to discriminate between bad and good research, and where to find good information. Sit down with your favorite internet consuming device, grab your favorite snack and drink, and enjoy.

Vaccine skeptics – let’s be clear, they are really science deniers

vaccine skeptics

I get so tired of this, the press describing vaccine deniers as “vaccine skeptics.” I wish the press would stop doing this, but no matter how much we say it, we continue to see it. I took the cantankerous Orac’s suggestion to Google “vaccine skeptic” and “Robert F Kennedy.” And, I got over 2 million hits. Two million!!!

Now, you might be asking yourself, “self, why is this feathery dinosaur getting all cranky about whether these people are called skeptics or deniers?” Because skepticism, even to the lay person, implies that the person has some legitimate beef with the science of a topic based on a thoughtful and unbiased review of said science. That is actually the furthest thing from the truth for these so-called vaccine skeptics.

Besides I’ve been cranky and snarky about misusing the term “skeptic” in science for years. And when this feathery dinosaur sees the press lending some legitimacy to the illegitimate beliefs of Robert F Kennedy Jr, it requires some cranky commentary (although the crankier Orac took some wind out of my sails).

Science deniers use false equivalence to create fake debates

This article is #3 of the 12 most popular posts on Skeptical Raptor during 2015. This article discusses how science deniers employ false equivalence to create fake debates.

If you read a news article, Google a scientific topic, or watch TV, you’d think that some scientific principles were actually being debated by scientists. The unfiltered information about important scientific subjects allows the science deniers to use a false equivalence to make it appear that the often minority, and scientifically unsupported viewpoint is equivalent to the scientific consensus which is based on huge amounts of published evidence.

From listening to the screaming and yelling, you would think that scientists aren’t sure about evolution, vaccines, global warming, and the age of the earth (or even the age of the universe). There are even those who think there’s a debate that HIV doesn’t cause AIDS. It’s because some news sources think there’s a debate, so bring one person to represent one side, and one for the other, and the person screams the loudest often wins.

Opinion – vaccine deniers annoy the shit out of me

This is part of my series of opinion pieces. As I’ve written, it is not meant to be supported by evidence or data – unless I link to evidence. Then it is.  

Vaccine deniers, or anyone who is antivaccine for any reason, are a difficult group. They have ideas that are just unsupported by any factual evidence. They have an opinion that they’ll hold on to as if it were a commandment from Thor.

Again, as I’ve written before,

[infobox icon=”quote-left”]Even if you believe that your opinion is right, does not make it so. It’s still wrong. And just because you can troll the internet finding others who share that misconception, again does not move it into the realm of fact, it merely means you’ve found like-minded people who are also wrong. Your wrong opinion is still wrong, and it has no validity. None.[/infobox]

The opinion that vaccines are neither safe nor effective is simply wrong. The vaccine deniers want to claim there is a scientific debate. No there’s not. The vaccine deniers want to claim that their opinion is more valid than the mountains of evidence. It isn’t.

Let’s make this clear – the antivaccination cult is wrong. We’re going with that assumption, because it is valid, and it is supported by mountains of evidence. And just because they whine loudly, they’re still wrong.

So how do they get there? Here are some of my “opinions” of what led them to being so wrong.

Richard Dawkins GMO position is made clear to Prince Charles

During the late 1990s, Richard Dawkins, noted secularist, author and evolutionary biologist, wrote an open letter to Prince Charles, noted promoter of pseudoscience and heir apparent to the British throne, about the Prince’s hostility to science. Even though Richard Dawkins GMO letter was written more than a decade ago, the salient points still ring true today:

…Sir, I think you may have an exaggerated idea of the natural-ness of ‘traditional’ or ‘organic’ agriculture. Agriculture has always been unnatural. Our species began to depart from our natural hunter-gatherer lifestyle as recently as 10,000 years ago – too short to measure on the evolutionary timescale.

Wheat, be it ever so wholemeal and stoneground, is not a natural food for Homo sapiens. Nor is milk, except for children. Almost every morsel of our food is genetically modified – admittedly by artificial selection not artificial mutation, but the end result is the same. A wheat grain is a genetically modified grass seed, just as a pekinese is a genetically modified wolf. Playing God? We’ve been playing God for centuries!

Richard Dawkins’ GMO ideas reflect real science, based on everything we know about genetics, agriculture, and biochemistry. Even though Dawkins letter was written a decade before the anti-GMO forces decided to make it a thing, it is still salient today.

Boosting the immune system – sorting science from myth

boosting the immune system

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.

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


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. Continue reading “The zombie anti-vaccine lie–Peter Doshi and the appeal to authority”
