[Guest Post] The Importance of Skepticism and Critical Thinking in American Society

Posted on by

This post was written by a fellow skeptic and student of psychology, Matthew Facciani.

At best, a lack of skepticism and critical thinking in our society will leave humanity uneducated, insipid animals. At worst, it will be the cause of our ultimate demise.

To begin, I would argue that critical thinking (disciplined thinking that is clear, rational, open-minded, and informed by evidence) is related to and facilitates the process of skepticism (the method of suspended judgment or systematic doubt). In order to be skeptical, you must be able to systematically pick apart problems with the concept or idea. By utilizing critical thinking in one’s skepticism, we can challenge fixed beliefs and continue to advance our society with scientific, artistic, social, and other pursuits. Additionally, employers strongly value critical thinking in their potential employees and critical thinking skills are positively correlated with GPA.

Despite the obvious importance of advancing mankind, some individuals are actually opposed to teaching this kind of thinking. The Republican Party of Texas’ Official Platform explicitly stated they were against the teaching of critical thinking in public school classrooms (quoted from their platform: “We oppose the teaching of… critical thinking skills”). It is astonishing that these elected politicians would even consider such a position, let alone have it in their official platform.

This certainly reflects a problem in American society with regards to the values of critical thinking and skepticism. In his book The Demon-Haunted World, Carl Sagan discusses the problem with not valuing these types of thinking in our society. He mentions that even people who may want to study science can be overwhelmed by pseudoscience, and science is “often filtered out” before it reaches us.

The fact that scientists like Sagan are critical of our scientific inadequacies would not mean much if it not for the data that backs up their statements. Americans have embarrassingly low scores in worldwide comparisons of scientific literacy, science, and math. Skepticism and critical thinking are simply not valued in American society, and the data supports it.

Because skepticism and critical thinking are not cultivated in American society, many Americans cannot tell when they encounter something that is pseudoscience (such as homeopathy or astrology). Someone may want to learn about scientific research, but due to our society’s scientific climate, people are inundated with pseudoscientific claims. Furthermore, with the advent of the internet, there is so much information about everything so you can find arguments for any position–with sound evidence or without.

However, a keen understanding of science makes it easy to determine which claims have a substantial amount of evidence. For example, climate change has been documented as a real and problematic phenomenon by many, many researchers. But a few vocal people have found “evidence” against climate change that makes people think twice–as they should when presented with conflicting data. However, any scientifically literate person should be able to see that the overwhelming evidence is that climate change is a real phenomenon and the few studies against it are outliers, poorly done, or cherry-pick data based on their biases.

These biases also impact how people deal with scientific claims in general. People may blindly follow someone who they think is in charge or an expert without analyzing things for themselves (see Milgram’s obedience study). People also see others following these “experts” and are likely to try to conform (see Asch conformity studies). When many people are already blindly following perceived authority figures, it is likely to continue because people do not want to be nonconformists, and the cycle continues. It takes more of a psychological effort to research things for oneself as it is, but couple this with a cultural environment that does not foster critical thinking, skepticism, or science, and we have a legitimate problem.

Furthermore, science in general is often misrepresented in the media. My own field of psychology is often decimated by its public representation and perception. I am technically getting a PhD in experimental psychology, but if I say the word “psychology” to an average person on the street, they think I will psychoanalyze them on a couch, read their mind (though, ironically, my research is actually like mind reading in a scientific sense), or engage in some other pseudoscientific method they saw on television. So I often tell people I study neuroscience because it has less stigma compared to psychology–though people are less likely to know what neuroscience even is!

Most other sciences deal with these issues, as well. The average American is simply not inclined to research or understand scientific concepts because skepticism and critical thinking are not valued in our society. Listening to what people say on television is often good enough for most people. It may not directly impact one person who doesn’t know what an experimental psychologist actually does, but that mindset of incessantly accepting information without challenging it can have catastrophic consequences. We are left with a critical mass of people who do not challenge information presented to them. They blindly follow what perceived authority figures tell them without a second thought.

Critical thinking allows people to dissect and analyze information, and skepticism prompts them to question the information that’s being presented to them first. So I ask, I plead, whoever is reading this–please stand up for the importance of skepticism and critical thinking. Write to your local politicians telling them about it. Do not let someone say something mindless and unfounded without challenging them. We need to foster an environment in which people feel comfortable challenging ideas and concepts. Once this happens, many more people will be thinking critically about our society’s problems and greater progress will occur.

He completed his undergraduate education at Westminster College in Pennsylvania, receiving a B.A. in Psychology with honors.

Abortion and Suicide: A Spurious Link

Posted on by

In South Dakota, it is now legal to require doctors to tell women seeking abortions that they are putting themselves at risk for suicide.

This move is brilliant from a PR standpoint. Unlike banning certain types of abortions entirely or, say, forcing women to undergo invasive screenings that are medically unnecessary, this seems completely apolitical when you first look at it. Don’t people deserve to be informed if they may be increasing their risk for suicide? Don’t we all agree that suicide is a Bad Thing?

However, something tells me that this is actually another attempt to scare women out of (what should be) a normal, socially acceptable medical procedure.

First of all, the inconvenient truth here is that credible research consistently shows little or no link between abortion and poor mental health. One 2008 study reviewed the literature and found that the only studies that seemed to show such a link had very flawed methodology, whereas the studies that were well-designed showed no links. (Damn liberal academics!) And here’s another study that showed no such links. And here’s a thorough debunking of a study that did claim such links:

Most egregiously, the study, by Priscilla Coleman and colleagues, did not distinguish between mental health outcomes that occurred before abortions and those that occurred afterward, but still claimed to show a causal link between abortion and mental disorders.

In other words, that study actually tried to use mental health pre-abortion to confirm a hypothesis about mental health post-abortion. This is simply not how you do science. And it’s especially bad here, because according to the American Psychological Association, guess what the best predictor of mental health post-abortion is?

Across studies, prior mental health emerged as the strongest predictor of postabortion mental health. Many of these same factors also predict negative psychological reactions to other types of stressful life events, including childbirth, and, hence, are not uniquely predictive of psychological responses following abortion.

That’s right. Shockingly enough, the best predictor of mental health is, well, past mental health. And poor mental health predicts poor response to all sorts of stressful events, of which abortion is only one example. Another one being, for instance, childbirth!

Compounding the bad science here is that, unlike physical side effects,suicide isn’t something that just happens to you suddenly and without warning. People don’t just suddenly wake up one morning and decide to kill themselves. Suicidality is a complex process that involves factors like genetics, family history, environment, social support, mental illness, and life circumstances. For instance, here are some things that, according to research, actually increase one’s statistical risk for suicide:

As you can probably surmise, not all of these correlations are also causations. While mental illness and drug addiction can actually cause suicidal behavior, being intelligent and being LGBT probably cannot. In the latter case, the causative culprit seems to be (surprise surprise) institutionalized discrimination and homophobia. Before I get too off-topic, let me point out the irony in the fact that, despite this well-known risk faced by LGBT youth, I don’t see any of these pro-lifers advocating for an end to homophobia.

That’s why something tells me that nothing about this court ruling actually has anything to do with suicide prevention.

Although the court’s ruling does at least acknowledge that abortion probably doesn’t cause suicide, it nevertheless states that “conclusive proof of causation is not required in order for the identification of a medical risk.” This is probably true, but it only makes sense from a physical health standpoint. If studies show that people who get a certain elective medical procedure are much more likely to, say, experience headaches or nausea or numbness, you don’t necessarily need a causative study to conclude that there’s a reasonable chance that these symptoms were caused by the procedure (assuming, of course, that there was no illness present that might be causing them). Furthermore, there’s a difference between saying “This procedure may cause you to experience cramps and headaches” and saying “This procedure may cause you to kill yourself.”

The truth is, mental health doesn’t work that way. A person who gets an abortion might experience mental side effects because of the stress of having gotten pregnant accidentally and been forced to decide what to do, perhaps without the support of a partner or family. Furthermore, any invasive medical procedure can be stressful and worrying for many people–especially one like abortion, which is consistently portrayed as more painful and dangerous than it really is.

And this is all made even more complicated by the fact that the faulty studies in question were actually studying mental health before the abortion. Perhaps a person with poor mental health is more likely to seek an abortion in the first place–say, if they feel that they aren’t mentally capable of raising a child at the moment.

Ultimately, decisions about what to tell a patient should be left up to the people who know most: doctors (with, of course, a reasonable amount of regulation to prevent malpractice). If a doctor can tell that a person seeking an abortion is going through a lot of mental distress, then that doctor may want to gently recommend counseling and perhaps give out some hotline numbers–and training doctors to recognize signs of mental health troubles is always a good thing.

But doctors should not be mandated to fearmonger to their patients. They should especially not be mandated to serve a pro-life agenda.

Is Homosexuality “Unnatural”?

Posted on by

Spoiler alert: no.

First, let’s define “natural.” Here’s what Merriam-Webster has to say:

  • “being in accordance with or determined by nature”
  • “having a specified character by nature”
  • “occurring in conformity with the ordinary course of nature : not marvelous or supernatural”
  • “existing in or produced by nature : not artificial”

For something to be “unnatural,” then, it would have to be the opposite of these things.

And now here are some facts about homosexuality:

  • Same-sex attraction exists among humans all over the world.
  • Although there’s no such thing as the “Gay Gene,” plenty of research has suggested that ties do exist between genetics and sexual orientation.
  • While some research has shown that one’s environment can influence their sexual orientation–for instance, a study showed that gay men report less positive interactions with their fathers than straight men–such factors aren’t exactly up to the individual to choose. (Also, one can’t really determine causation in cases like that.)
  • In general, psychological authorities agree that homosexuality is caused by an interaction of countless factors, usually develops in early childhood, and is not a choice.
  • There is no evidence that sexual orientation can be forcibly changed through “conversion therapy” or any other methods. (However, one’s orientation may be fluid and can sometimes change on its own over time, just like other types of sexual preference.)
  • Even animals can be gay! Homosexual behavior has been documented in tons of different animal species, such as penguins, pigeons, vultures, elephants, giraffes, dolphins, lizards, sheep, and, curiously, fruit flies and bedbugs. Bonobos, meanwhile, are almost entirely bisexual.

Compare this list to the definitions of “natural” above. Could it be that homosexuality is just a part of nature?

Some people like to claim that because homosexuality is “unnatural” because it’s maladaptive in terms of evolution–after all, how are you supposed to pass on your genes if you can’t have biological offspring?

First of all, for various reasons that I may elaborate in a future post, I don’t believe we need to let evolutionary concerns dictate our behavior. Second, there are plenty of other conditions that people are born with that aren’t evolutionarily adaptive–albinism, for instance. Nobody goes around railing about how albino people are “unnatural.” (Except perhaps in parts of Africa, where the condition is heavily stigmatized. But it goes without saying that what happens to albino people in some cultures is deplorable.)

That’s not even to mention the fact that, last I checked, it’s not anybody’s business whether or not particular individuals want to pass their genes on to the next generation or not.

The reason I’m writing about all of this is because homosexuality’s supposed “unnaturalness” is a common justification given by bigots for why they oppose gay rights. (For some examples, see here, here, and here.) As usual, however, their arguments have nothing to do with the meaning of the word “natural” or with current research on homosexuality. (At least among Christians, the idea that homosexuality is “unnatural” comes from bible verses such as Leviticus 18:22, which refers to same-sex relations as an “abomination.” There’s a vague line of reasoning if I ever heard one.)

Therefore, I wish they’d just give the real reason they don’t support gay rights–that they don’t like gay people, don’t wish to examine why they feel this way, and would rather the LGBT community just shut up and stop making their lives so difficult.

The Complete Idiot’s Guide to Breast Cancer Awareness

Posted on by

If you have ever seen a bunch of women posting Facebook statuses with a random color, or a location where they “like it,” and felt a mix of confusion and frustration, you are not alone.

These memes are part of an effort for breast cancer “awareness,” a word that I use cynically here and only in quotation marks. The color meme referred to women’s bra color, and the location one referred to where they like to put their purses. Of course, they made it sound sexual to attract more attention: “X likes it by the bed”, “Y likes it in the closet,” etc.

Now, an acquiantance of mine (who also happens to be the Director of Health Promotion and Wellness at Northwestern University, and therefore isn’t entirely ignorant about these things) has reported that this stupid trend still has not died.

Perhaps even less sensically, the latest iteration of this meme is people posting stuff like “is going to New York for five months” or “is going to Las Vegas for twelve months,” and this, too, is supposed to elicit friends’ queries and be met with the response that it’s for breast cancer “awareness.”

As anyone with even a modicum of critical thinking skills can tell you, such a status, when finally deciphered, tells you exactly one thing: “There is a thing called breast cancer and you should know about it.”

Yes, yes there is. But could we finally get beyond that?

For instance, here are some actual facts about breast cancer:

If you’d like to do some actual good, why not spread this information around?

Besides that, here are some other ways you can help:

  • Volunteer to provide support for people battling breast cancer. (This is even easier if you know of such a person. You can help by driving them to doctor’s appointments, making them meals if they’re too tired, babysitting their kids, or just being there to listen.)
  • Donate to charities that provide such support, or to organizations that fund research on breast cancer. Here are some to get your started: Susan G. Komen for the Cure, the National Breast Cancer Foundation, and the National Breast Cancer Coalition. With a quick Google search, you could find local charities, charities that cater towards a particular demographic that you belong to, and so on.
  • If you want to go beyond simply giving money, participate in charities’ fundraising events, such as Susan G. Komen’s Race for the Cure. That way you get to raise money while meeting other people who care and physically showing your support for survivors and people battling breast cancer.
  • If you’re politically liberal, be an activist for government initiatives that fund cancer research, education initiatives, support for cancer patients, expanded insurance coverage, etc. One good place to start: ask your representative to support H.R. 3067, the Accelerating the End of Breast Cancer Act of 2011, which proposes an initiative to end breast cancer by 2020.
  • If you’re studying medicine or biomedical engineering, consider making cancer research your focus. Or work as a research assistant in a lab that studies cancer.
  • Buy products from companies that donate to breast cancer research (but beware of pinkwashing).
  • Similarly, if you happen to own a business or want to start one (and I know many of you Northwestern students do), consider donating a percentage of your profits to breast cancer research.
  • If you’re going into journalism and you’re interested in health, consider writing about breast cancer. Not everyone has enough knowledge to decipher academic articles; you can be the one who makes that information accessible to those who need it.

As you can see, some of these require your time and money. Others do not. The few seconds that it takes you to type your stupid status could be better spent posting a link to an important recent article about breast cancer.

And now, I get it. Cancer is a terrifying thing. The amount of information available about it could fill books upon books, and some of it is constantly going obsolete or being revised. Even I felt a bit overwhelmed just looking at the few websites I looked at to research this article.
I also get that when your friends are posting oh-so-funny things on Facebook, you want to join in the fun. Trust me, I was in middle school once, I know.

But I have some unfortunate news for some of you: neither I, nor breast cancer survivors, nor families of breast cancer victims give a flying fuck what color your bra is or where you like to put your purse, cutesy sexual innuendo notwithstanding.

If you’re old enough to make sexual innuendo, you’re old enough to educate yourself and others about breast cancer (and, for that matter, anything else you think people should be educated about). Let’s stop selling ourselves short here.

*edit* Another reason I just thought of to hate these memes–they are generally restricted to women only, and women aren’t “supposed” to tell men what they mean, thus constructing breast cancer as a “girl thing.” Not only do men witness their friends, girlfriends, wives, mothers, daughters, sisters, etc. fighting breast cancer, but some men actually get breast cancer, so it’s not only a women’s problem.

Anyway, there is enough of a stigma placed on men who get breast cancer without its promotion through this meme.

Update (2/2/2012): In case anyone’s going through my archives and reading old posts, let it be known that I officially withdraw my support for the Susan G. Komen Foundation in light of its defunding of Planned Parenthood.

Preventing Depression

I love it when people who actually know what they’re talking about confirm something I’ve believed for ages.

In this case, a study at the Feinberg School of Medicine (that’s Northwestern’s med school) showed that one out of every four or five college students who come to their school’s health center may be suffering from depression. The study also recommended that colleges should start screening students for depression. This way, they might even be able to pinpoint students with minor depression and help them get treatment before their depression worsens.

Ever since I’ve started seriously reading about psychology and depression, I’ve felt that we should start taking a preventative approach to it–not just in colleges, but everywhere. Depression tends to worsen with time, and even when it does remit on its own, it usually comes back later, with more intensity. Furthermore, distorted thinking patterns seem to precede the development of a full-blown depressive episode, so why not address those earlier rather than later?

For instance, parents take their kids to the doctor to make sure that they’re growing at a normal rate and developing the cognitive abilities they’re supposed to develop–why not also check to make sure that kids aren’t developing negative and maladaptive thinking patterns that could increase their risk for becoming depressed later?

You might think that kids are too young to show definitive patterns, but I think that’s false. My own little brother, who’s eight years old, constantly complains that he’s fat and needs to exercise, despite being underweight for his age. He also says that everyone at school hates him (they don’t) and that his school is awful and should be burned to the ground (and various other sentiments that have gotten him sent to the principal’s office before). Perhaps most importantly, he also has a pervasive family history of depression.

The unfortunate truth is that society views mental illnesses as fundamentally different from physical illnesses. One is a straightforward matter–you go to a doctor for checkups, and if something is wrong, you receive treatment. The other is for some reason shrouded in mystery, and people generally don’t go seek help for it until they’re already barely functioning.

As recent scientific developments are beginning to show, however, it may be that all mental illnesses actually have a physical basis. More and more psychologists and psychiatrists (notably, Peter D. Kramer of Listening to Prozac fame) are starting to take this view. If they’re right, it follows that we should try to take a preventative approach in treating mental illness, not a palliative one.

However, many people still have negative attitudes about the idea of psychological screening. One of the students quoted in the article linked to above said that these screenings are a bad idea because someone could just “be having a bad day” and–oh, the horrors–get recommended for counseling. First of all, however, counseling isn’t exactly the same as taking antibiotics or getting a spinal tab. Second, that just means that we need to develop better depression screening tools, not that we shouldn’t screen for it at all.

In college especially, conditions like depression can take a turn for the worse rather quickly, as evidenced by the several suicides we’ve had on campus while I’ve been a student here. Every time a tragedy like that occurs, friends and family are often quoted as saying that they “never saw it coming.” Maybe a professional psychologist would’ve.
