Guest Post: Magical Thinking


Faith is viewed dramatically differently by the many different types of nontheists. There’s no one philosophy of thought held by nontheists in a group – we’re a disparate bunch – since we are largely unified merely by lack of belief in a god or gods. Some see faith and religion as not being such a bad thing at all. On message boards and blogs, you will often hear cries for moderation in our discourse, saying that we can all coexist with our many and myriad beliefs, and we should all live and let live. What’s the harm in that?

The harm is in what James Randi calls “magical thinking”. This is a product of faith, as I see it. Magical thinking is, at its most basic, allowing one’s self to accept arguments without any logic, evidence, or reasoning. Religious people accept that their god exists, miracles occurred, and any number of extraordinary things. The more educated theists will put forth arguments born of their faith-based logic, but when these are torn down by competent nontheists, all that is left is faith. “I just know.”

When asked if religion does any harm, therefore, I must emphatically say "yes." Even the most moderate of religions require, by their very definition, magical thinking. It is bad enough to see this in adults who refuse strong evidence which conflicts with their beliefs. I find it more abhorrent still that this magical thinking is then taught to their children. This can only stymie their intellectual growth, by providing logical dead-ends to their questions. Worse, the parents would then go on to glorify that same willful ignorance - faith is a virtue, after all.
A person who cites faith as a reason for believing something is proudly claiming they hold their belief with no supporting evidence asked for or given.

Again and again through history we've seen that sort of magical thinking be harmful. Consider the anti-vaccination movement: A group of people led by a vocal spokesperson, Jenny McCarthy, whose claims are dubious at best. However, they've "seen" it happen, or they know someone who has had it happen to them - their child or their friend's child or their aunt's first cousin twice removed had a friend who definitely caught autism from their MMR shots. A facetious example, to be sure, but this is how the “evidence” is presented. As an example, take one of Jenny McCarthy’s own blog posts. “I know children regress after vaccination because it happened to my own son.”

Prior to this statement, McCarthy quoted the parent of one of the 12 patients in Andrew Wakefield’s original study (more on this in a moment), who makes the other side of this claim.
“To hear that my son's gastrointestinal condition has been extensively refuted, by unqualified and ill-informed individuals who have never laid eyes on him, looking at and mis-interpreting scanty medical notes without the courtesy to ask for our version of our son's early childhood, flies in the face of everything that the medical community and its professional bodies seek to represent.”
This person may have legitimate issues with the studies done that concluded, of course, that there was no link between her child’s gastrointestinal disorder and autism. However, she is attempting to reach a hypothesis from an already defined conclusion, which flies in the face of the scientific method. In other words, she has seen this happen, and “knows” what must have caused it; therefore it must be shoddy science that refutes her particular claim.

The research, the evidence, and the scientific community is overwhelmingly against them. The first one to propose a vaccine-autism link was Andrew Wakefield, and his work was recently (finally!) discredited by prominent UK medical journalist Brian Deer. It was proven that Wakefield accepted upwards of $800,000 from lawyers who wanted him to prove that the vaccine was unsafe. The scientific journal that originally published Wakefield’s work has since retracted it, publically and finally refuting the pseudoscience once and for all.

In response to all this, of course, Jenny McCarthy was not deterred. Here’s a rebuttal to this blog post by “Orac” of Scienceblogs.com, which contains citations, links, and a lot more science than I’m capable of producing.

This is nothing short of willful, deliberate ignorance, despite overwhelming evidence against this vaccination-autism link. The original promoter of the idea has been debunked as a fraud. Not a single shred of evidence has ever turned up in favor of the idea. But still the idea persists, because McCarthy and those who follow her “believe” it to be true. They “know” that their child is afflicted by autism because of vaccines, and it seems like nothing will change their minds.

Children are dying because
people trust her more than
medical professionals
This brings me back to my original point. What’s the harm? They’re welcome to their own crazy ideas, so why get so worked up about it? As of 2008, measles have become endemic in the UK. The reason? Low MMR coverage – the same vaccine that McCarthy and other anti-vax types rail against the hardest. Whether this was caused directly by anti-vax efforts is irrelevant. It shows us that there is a pressing need for vaccinating our children, and it’s not to line pharmaceutical company’s pockets. It’s to maintain immunity as a species to diseases that should have been wiped out. A compendium of other examples from right here in the USA, check out the Jenny McCarthy Body Count website, which catalogues death and hospital reports from the CDC concerning illnesses in people who were never immunized, and more on Jenny McCarthy’s role in the anti-vax movement.

Religion is not the root cause of this sort of willful ignorance that can lead to serious harm. Religion is just a symptom of magical thinking; taking things on faith, or anecdotal evidence, or just “feeling” something to be so. Religion does, however, reinforce that faith is a good thing, to be prized and rewarded.

Instead, I say, question everything. Check your sources and cross your references; be a skeptic. Read up on What’s the Harm to hear sobering stories about the specific dangers of neglecting critical thinking. Only when we all think critically can we surmount the dangers posed by magical thinking.

What Do We Do With Crazy Ideas? The Anti-Vax Movement

The Anti-Vax movement.

It's one of those crazy, unfounded, ideas that makes me very angry, even more than normal, because I was taken in by it for a while. I heard it in passing, and the idea of "Oh yeah, we really do pump our kids full of so much stuff so early" stuck. Over time it evolved to "Huh, maybe there's some credibility to this, so many injections so young can't be healthy for them. I don't have kids yet, but I'll look carefully into which vaccines I'll allow." It might have progressed further, but Mike brought it up at one point, I voiced my opinion, and he (nicely) ridiculed me out of it. Since then I've done my research, and I'm much more hesitant to accept an idea just because it sounds plausible.

Here's Penn and Teller's take on it (NSFW language):



The Anti-Vax movement brings up a difficult question for which I can see two answers:

1. We combat the crazy idea early, with the outcome of debunking it or giving it credibility where it would otherwise have none.

2. We ignore the crazy idea, and allow it to fall off the radar unnoticed or, in the case of the Anti-Vax movement, gain a large foothold.

Which do you think works better? Is there a third option that I've missed?

Never stop questioning,

Guest Post - Amanda on her agnostic theism

This entry is about my personal beliefs. I would never expect anyone to read it and change their own beliefs; it's simply an informative essay. If you have any questions, I'd love to answer them in the comment section.

In order to fully understand my religious beliefs, I need you to first strip away the title of “Jewish.” I will re-apply this title later in the post, and explain the part it plays. But first you need to understand my core religious beliefs, which are my own and not necessarily a part of Judaism (although they were developed because of the lessons the Torah has taught me).

In scientific pursuits, we first ask a question. Once we investigate this question, more often than not, we end up with more questions rather than finding a definite answer. Eventually, we end up with some answers, and a heightened understanding of the universe and its structure. But even then, there is often a gap in our understanding. In order to illustrate this, I like to picture a stone arch. Each piece in the arch is necessary for it to stand, but most important is the keystone at the top – the wedge-shaped piece that allows the two sides to support one another. Imagine that the stones in the arch are facts; knowledge derived through scientific endeavors. And now imagine that the keystone is invisible. We can’t see it, but we can see its outline, and we can use that information to inform our understanding of its structure and function. We know there must be something holding up the other pieces, and we know where it must sit, and its approximate shape. Moreover, we can even assume it’s made of the same material as the rest of the arch. But we still can’t see it or know its exact nature for certain.

It is my belief that the last unknown in each scientific field will all lead us to the same conclusion. We will eventually find a construct at the center of existence that affects all things, is a part of all things, and is necessary and essential to existence. I originally found this concept in the Hebrew name for God. It has four letters (which is unique because all other words in Hebrew have three-letter roots), which stand for “I Am Who Am,” and has been interpreted to mean that God is the source of existence. Not in the sense that he woke up one day, pointed his finger and created the universe, but in the sense that he is in everything, he is everywhere, he IS existence itself. Eventually, I realized that because science is the pursuit of studying the universe, and God is the universe, there is no reason why religion and science can’t both be right.

This is where I get to the core idea that makes my personal beliefs possible. I find that Christians often find this concept challenging because it so directly contradicts what they have been taught. Aside from that, however, it’s a fairly simple idea: the stories told in religious books are metaphors. Every component of the Bible, the Torah, the Koran and any other myth used to worship or explain our existence is metaphor meant to educate us about the nature of the universe, and moreover, to inspire us to explore it. This goes for God as well.

I don’t believe God is a bearded father figure in the sky, looking down on us and creating miracles. That version of God is a story, told with the intent of inspiring people to explore the world around them, and to ask questions of nature, and never be satisfied with just one answer. As such, no religious book is necessarily wrong or right. They are all attempting to describe the same thing.

I do believe, however, that it’s wrong to teach someone to ignore science. And it’s wrong to emotionally handicap someone by teaching them that God should be feared, life should be feared, and the afterlife is a giant test of their moral fiber. I believe it’s wrong to tell someone to shut their eyes and let the universe do the work for them. And I believe it’s wrong to tell someone that prayer provides results. All of these things make people weak and vulnerable, and blind them to the beauty of the universe. It’s healthy to embrace randomness and statistical probability. Nothing happens for a reason, unless you consider causal factors and other conditions surrounding the event to be a reason.

In my life, I use the ceremonies surrounding Jewish holidays to acknowledge that life is diverse, the universe is big and weird and full of randomness, and that there is something out there worth knowing. I pursue this something through my scientific pursuits, and celebrate it through Judaism.

Theists think too,

Neil Degrasse Tyson is a Rock-Star of Science

More accurately, he is a rock-star of science literacy. We need more educators stressing the importance of learning to ask the right questions, I count myself very lucky to have had several.



In search of reason,
