Remember This: Ginko Biloba Won’t Improve Your Memory

Posted by skeptologic on November 15, 2009

My wife enjoys watching “The Doctors,” a talk show that features four doctors presenting medical information and answering questions on a wide variety of topics. I have always been very concerned about getting the highest quality medical information for my family, and make it a point to be highly critical of anything that might wave the red flags of pseudoscience. I have watched this show with my wife a few times and found it to be pretty good, but as with most information presented in the mass media, I have definitely seen the pseudoscience creep in a few times. When it does, Dr. Travis Stork, one of the hosts, is usually quick to point out that there is no evidence behind the particular item, or that it should only be used for relaxation, not a treatment, etc.

On one episode they were talking about ear candles, a particularly stupid alternative “treatment” in which you stick a hollow candle in your ear and light it (what could possibly go wrong!?) in order to suck out “negative energy.” One of the other hosts, Dr. Jim Sears, credulously stated that there might be something to this, while Dr. Stork rightfully rolled his eyes and said something to the effect of “Come on, what could this possibly do?” I have tried to equip my wife with the tools to spot nonsense when it comes to medicine (she is not very interested in science, except as it relates to health) and she now comes to me and mentions when she sees something she suspects of being woo-woo on the show. That and Dr. Stork’s apparent skepticism made me feel pretty good about the show for the most part.  It’s not perfect, but it’s not in the same league as the horrible, despicable, harmful nonsense presented on The Oprah Winfrey Show.

Unfortunately on a recent show I saw something that really bugged me. At the end of the show, Dr. Stork did a quick segment touting the herb Ginko Biloba as a treatment for memory loss. He said that some studies had shown a positive effect. I am curious Dr. Stork, exactly what studies are you referring to? I searched pubmed and all I found was a bunch of studies that showed that it did not work. Let me reiterate my stance on herbs: herbs are drugs. There is nothing special or magical about them. Some people prefer them because they are “all natural” and because of that they think they are somehow better than pharmaceuticals in pill form. If we test an herb properly and it is found to have a beneficial effect, it can be used medically. But the problem is that there are so many herbs out there that are popular as folk remedies that have not passed these tests. At least he warned that the herb can vary in purity and dosage, and I have heard the doctors on the show mention that if you are taking any herbs or supplements you should tell your doctor. Good advice, because they are drugs, which can have side effects and interact with other drugs you may be taking. All natural means nothing.

It bothers me that they would promote what amounts to nothing more than a pop culture belief for Ginko Biloba over the real scientific data. And we should consider that if Ginko did show a real effect, the pharmaceutical companies would figure out what compound was beneficial, purify it, make it into pills and make billions of dollars. Why don’t they? Because they have to prove their drugs actually work in real scientific clinical trials. They can’t sell drugs without proof of safety and efficacy, the supplement makers can and do.

And for those of you reading this who are going to email me a study that shows a tiny effect that is barely more than statistical noise, or that showed a small effect is rats or something, JAMA published the results of a gigantic eight year study on Ginko Biloba for dementia. The results? It does not work. For a review and explanation of the results of this study, you can go here, Dr. Steven Novella explains it way better than I can.

Note to Bill Maher: You Can’t Pick and Choose with Science

Posted by skeptologic on September 23, 2009

I really hate it when celebrities that I like do, say, or support stupid and harmful things. Most celebrities are into one wacky thing or another, so this is pretty much impossible to avoid. One celebrity I generally like is Bill Maher. He’s really funny, and he is pretty rational when it comes to most things. He is an outspoken critic of religion and 9/11 conspiracy theories for example. As a matter of fact he calls himself a rationalist and champions science in his criticism of those things. But last Friday on his show “Real Time with Bill Maher,” he criticized western medicine in favor of alternative medicine. Let me say again that I do not like the term western medicine. It is misleading in that it gives the impression that where a treatment originates has anything to do with its validity. I prefer the terms science based medicine or scientific medicine, which I will use henceforth. In the video clip, Maher puts forth a question to his panel from one of his viewers:

“Will the implementation of universal health care help or hinder alternative medicine?”

One of the panelists, Jefferey Toobin, starts to say exactly what I would “There’s only medicine, if it works it works, if it doesn’t it doesn’t.” But Maher quickly interjects with a pro alternative anti-scientific rant. I will take his claims point by point:

“That’s not how this country works, often alternative medicine is illegal in this country you can go to jail for practicing it.”

This is not true, but it should be. There are lots of so called alternative treatments in this country that are perfectly legal. Homeopathy, chiropractic, reiki, acupuncture, and various detoxification “treatments” are all perfectly legal and some are even covered by insurance. Why in the world would anybody want quackery, and make no mistake that is what many of these treatments are, to be allowed? You want to be taken advantage of by snake oil salesmen with treatments that have absolutely no plausible scientific validity? What exactly is rational about that Bill? He goes on:

“Such as even suggesting any alternative treatment for cancer, you don’t understand how much the pharmaceutical companies have their tentacles wrapped around the government in this country. I don’t know whether Laetrile works, I know the shit they’ve been trying for the last 50 years doesn’t. I know they’ve made no progress as far as cancer in this country.”

Ah the old “Big Pharma” conspiracy.  I have news for you Bill, every large corporation “has its tentacles” wrapped around our politicians, not just the pharmaceutical companies. That is a totally separate issue than whether or not scientific medicine is better than quackery. And it does not mean that somehow doctors, pharmaceutical companies, and the government and all part of a grand conspiracy to keep us all sick for fun and profit. Offering alternative treatments to a person with a serious disease such as cancer should be illegal, because if that person avoids or delays real medical treatment, it can lead to their death. And “no progress” in cancer treatment for 50 years? First of all, there are many different types of cancer. They have made more progress with some than with others, but even if they hadn’t that still would not validate pseudo-scientific treatments in any way.

“There are people who actually go out of this country when they get cancer and some of them come back alive when they’ve been given a death sentence, but in this country you can’t talk about that.”

The logical fallacy here is anecdotal evidence. How does Bill know how all of the people who leave the country for cancer treatment and come back alive were cured? Where exactly to they go? What treatment do they get? Is his statement even true? What if they left the country and got a real scientifically valid cancer treatment that they could not get here for some reason or another? What if their cancer spontaneously went into remission? This has nothing to do with unproven non scientific medicine being a better solution.

He then defines alternative medicine as “holistic” and says “As opposed to drugs and surgery.”

So he’s opposed to drugs and surgery? I can’t understand why anyone would be opposed to drugs that can cure diseases and life saving surgery, but here is Bill’s reasoning:

“The reason why we have this giant health care problem is because people are so sick and the reason they are so sick is that the system we have now, western medicine, the non alternative system, only treats symptoms. That’s how they keep the scam going, if you only treat symptoms, of course people are going to get sicker. Yes, Nasonex will stop you from sniffling and will shove the mucus right down your throat.”

Wow. Let me say first that he is correct that there are some drugs and treatments that do only “treat symptoms.” For example there is no cure for the common cold, but when I get a cold I would at least like something to relieve the symptoms so I don’t feel like crap while I have it. The medicine he mentions, Nasonex, is an medication that treats allergy symptoms. I have no idea if it “shoves the mucus right down your throat” as Bill claims, but I do know that when I am suffering from severe allergies in the spring, I definitely want something to temporarily relive those symptoms. But his claim that the system we have only treats symptoms for everything and that it’s a scam is so demonstrably false it’s not even funny. Life expectancy has doubled since medicine became science based and we discovered what actually causes disease. Since then, through vaccination we have eradicated or marginalized many very serious diseases: Diphtheria, Pertussis, Hepatitis A and B, Polio, Small Pox, Measles, Mumps, Rubella, Tetanus, Varicella, HiB, Meningoccal, and Rotavirus. Not good enough for you? What about antibiotics? Millions of lives have been saved by antibiotics. They don’t just “treat symptoms,” they kill the bacteria that have infected you. And since we’re talking about cancer treatments too, chemotherapy kills cancer cells. It’s not perfect, it does not always work, and the side effects really suck, but it is not designed to just treat symptoms.  I can’t believe he also seems to have a problem with surgery. There are many types of conditions where surgery will absolutely save your life. I guess if Bill Maher gets seriously ill, he would rather have some crank stick little needles in his skin or something.

People do not get sick because of the system we have. People get sick because there are viruses, bacteria, and other things in the world that make them sick. Proponents of alternative medicine often use these kind of buzz-phases like “western medicine only treats symptoms,” “holistic,” “treating the whole person,” and “all natural” because their “treatments” are totally made up and have no scientific evidence or even plausibility to back them up. Bill Maher may not like the pharmaceutical industry (and I’m sure there are probably many valid criticisms of those and many other types of companies) but at least the pharmaceutical companies have to prove their products work  in real scientific clinical trials before they can sell them. Can you imagine if a pharmaceutical company were to sell a drug to the public for a serious illness that they knew was only a placebo? It would be a scandal! But alternative medicine does this all the time. Their treatments are usually nothing more than placebos and they don’t just give them away. Supplements, complimentary, and alternative medicine, there is your S.C.A.M.

What I do not understand is how Bill Maher can champion science when it fits with what he wants it to, and dismiss it for something else. He understands why evolution is true and why 9/11 conspiracy theories are not (even though he is a very outspoken critic of the Bush administration whom those conspiracy theories target), based on the scientific evidence. You can’t pick and choose what scientific data shows based on what you want to be true. Bill Maher calls himself a rationalist, but his disdain for science when it comes to medicine is not rational at all. In fact it is extremely dangerous. This is why while he may agree with skeptics on many things, but is definitely not a skeptic. Skeptics go with what the scientific data shows, even if that data goes against what they want to be true. I hope that if Bill Maher or anyone in his audience gets seriously sick that they will avail themselves of what science has to offer instead of quackery. It will probably save their lives.

Oprah and Dr. Oz Sue Quacks, how Ironic!

Posted by skeptologic on August 21, 2009

So Oprah Winfrey and Doctor Mehmet Oz are suing people for using their images to sell supplements online. The suit claims that “the public is being deceived into thinking the duo have endorsed products like acai berry, a freeze-dried energy booster.” So the queen of pseudoscience and Doctor Woo-Woo are all of a sudden concerned about the pubic being deceived? Cry me a river! Keep in mind that it does not say that they are concerned that the public will be duped into buying “health” products that do not work, but only deceived into thinking that they have officially endorsed them. How ironic.  Acai berry is just one ingredient in a whole fruit salad of nuttiness that gets promoted on The Oprah Winfrey Show. Here is just a small list: past life regression, The Secret, psychic powers (including the most harmful ones, so called psychics who claim they can help police find missing children), detoxing, anti-vaccination, energy medicine, Airborne, Suzanne Somers and her crazy hormone and vitamin mega-dosing, therapeutic touch, homeopathy, and much more. Look, I understand that nobody has the right to use their images without thier permission, but here is a free tip for Oprah and Doctor Oz: If you don’t want people to be deceived into buying quack products from quacks who are using your images to do so, stop promoting pseudoscience and quackery on your show!

My Favorite Episodes of my Favorite Podcast: Skeptoid

Posted by skeptologic on August 8, 2009

“You’re listening to Skeptoid, I’m Brian Dunning from Skeptoid.com.” Every Tuesday morning I can’t wait to hear those words and the topic that Brian will be covering that week. The Skeptoid podcast follows a simple, effective format. Every week Brian spends around five to ten minutes covering some paranormal or pseudo-scientific pop culture subject from a skeptical point of view. A couple of weeks ago the episode was about how we can make skepticism more commercial and more appealing to the masses. Brian argues that the key to this is to make whatever the presentation is fun, entertaining, and compelling first and foremost. I thought about this and realized that looking back at all of the Skeptoid episodes I had listened to, my favorites were pretty much the ones that had interesting subject I had never heard of before, tugged at my heart strings, or most of all made me laugh. I went to Skeptoid.com and scanned the episode list to pick out my top ten, which quickly became my top 15 and then top 25. The list was getting too long so I decided to cut it off at 15.

I first heard about Skeptoid from an interview Brian did on another podcast. I thought, well that sounds interesting, he’ll probably cover Bigfoot, The Loch Ness Monster, ghosts, Roswell, The Bermuda Triangle, etc, and run out of subjects pretty quick. Boy was I wrong. Skeptoid is currently on episode #165, Brian has stated he currently has over 200 subjects and growing to cover (if I remember correctly), and neither the Bermuda Triangle or Nessy have been covered yet! There was just way more baloney out there than I could have imagined, and it is much more harmful than I ever thought possible.

A couple of notes, I did not include episode #150 “Screwed!” While that episode was great, it was so different than any of the other episodes that I have to put it in its own unique category. I am also not counting the various listener feedback and student question episodes, since they all contain so many topics each. So anyway here is my list:

#15: Illuminating the Fatima “Miracle of the Sun” (episode #110): I like this episode because I myslef am of Portuguese descent and grew up hearing about this so called “miracle.” Brian has a very interesting take on what may have actually happened.

#14: Mercury, Autism, and Chelation: A Recipe for Risk (episode #55): This episode is one of the many examples of the harm that pseudoscience can do. A child died because he was being treated for heavy metal poisoning with chelation therapy, even though blood tests showed no such condition. Brian argues against the popular belief that mercury in vaccines causes autism. This episode came out in 2007, and since then there has been an avalanche of new claims (by Jenny McCarthy and others) about so called “toxins” in vaccines. The subject is so important that this episode could use a part two just about anti-vaccination activists and their current claims, but that episode would probably have to be an hour long. Luckily, Dr. Steven Novella and his crew over at Science Based Medicine are also doing an amazing job addressing this topic in great detail. Hopefully people will listen, otherwise we will continue to see outbreaks of terrible vaccine preventable diseases and many children may suffer and die as a result.

#13: Raw Food, Raw Deal? (episode #30): This one made me laugh on my commute and people on the train were looking at me funny. The claims of raw foodists are just so far fetched and silly that I could not help it. It’s the only example I can think of where Brian nearly laughed while recording his podcast. It  happened when he addressed the claim that cooked food is toxic (yes you read that right): “I’m not even sure how to answer this one. Obviously, if cooked food was toxic, everyone on earth would have died long ago. Generations ago. Tens of thousands of years ago. Every speck of evidence shows quite conclusively that everyone talking about this is, well, alive. Cooked food is not toxic, or else we’d be dead.” But then I laughed even harder when he delivered this gem when talking about the claim that cooking food renders it non-organic when in fact you would have to cook it at over 750 degrees Fahrenheit to do so: “So if you cook your food in a ceramics kiln, then yes, it is possible to chemically change it into a non-organic compound.” The episode is just hilarious and the claims are so out there, it was so much fun to listen to.

#12: Should You Take Your Vitamins? (episode #103): Something I had believed my whole life was shattered. Vitamin C does not help you prevent or get over a cold. I had no idea that this whole idea came from one book written in the 70’s, and that clinical trials had disproved it.  Brian also mentions “Airborne,” a supplement that claimed to prevent and treat colds and flu. I had also written about  the Airborne quackery myself a few months earlier, arguing that Walgreens should be sued as well for their knock off, Wal-Borne. Good news: Walgreens just got nailed too. Bottom line, you pretty much get all the vitamins and minerals you need from your food if you eat a balanced diet. You don’t need supplements unless you have a specific deficiency. Oh, and you can’t “boost your immune system” either. Brian said he was going to do a whole episode on that too. Looking forward to it.

#11: Despicable Vulture Scumbags (episode #89): In this episode Brian took the time to address a specific email from a listener whose friend had been diagnosed with ALS. Some jerks sold the victim a useless device called a Barr Wet Cell Battery. It made me feel terrible for both the ALS victim and his friend, who wanted to tell his buddy not to waste his time and money on the bogus device. Brian did a wonderful job giving the guy advice on what he should do for his friend. I was quite upset that people would try to make money off of someone’s ailment with bogus snake oil. They really are “despicable vulture scumbags.” I was in tears. Way to go Brian, you nailed it.

#10: Medical Myths in Movies and Culture (episode #78): “Never listen to your mother!” Oh this episode spoke to me! I’ll never forget one summer when I was a kid visiting family in Boston. After eating a huge lunch my cousins and I started cooling off by turning on a hose and getting wet. An older cousin of mine ran out of the house and screamed at me that by getting my feet wet after eating a big meal I could die. Even as a young kid I could remember thinking that there was no way that could be true. Why did she believe that? Her mother probably told her, and her mother before that. My own mother told me that I could get very sick by swimming right after a big meal (also not true). And I also got the “don’t crack your knuckles, you’ll get arthritis” and “don’t eat chocolate it causes acne” growing up, both of which Brian addresses in this episode. There are just so many of these that this should be a recurring episode. I’ll get you started on the next one Brian: eating pop rocks and soda will not cause your stomach to explode. Go!

#9: Coral Castle (episode #149): When this episode popped up on itunes, I said Coral Castle? What the heck is that? It was brilliant! Especially the video of Wally Wallington moving gigantic blocks around with only tools and methods known to the ancient Britons. He raises a 19,200 lb. block using levers, fulcrums, and gravity. I also like this one because it is a great example of a very common logical fallacy, the appeal to ignorance. Just because you can’t think of how ancient people could have built things like Stonehenge or the Giza Pyramids does not mean that it was not possible or that aliens or some supernatural force must have done it. It just means you have not considered enough possibilities.

#8: Organic Food Myths (episode #19): This was the very first Skeptoid episode I ever listened to, and it is still one of my favorites. Wow, talk about a sacred cow for so many people. Just read the comments on the online transcript for this episode. Brian has addressed them multiple times during the various listener feedback episodes and it looks like there will be a part two to this episode coming next week. People keep accusing Brian of being a paid mouthpiece for “big food.” Apparently there is big everything (big food, big corn, big pharma, big government, big dairy, who knew?) It’s amazing the amount of anger you can generate in people just by pointing out that organic farming does not necessarily mean that the food is grown without pesticides. Or that in most cases it is worse for the environment because you use more land to grow less food. Or that most organic crops are grown by the same companies that grow regular crops. Or that Trader Joe’s is not a small company. Or my favorite: that just because something (like organic pesticide) is “all natural” that it can’t harm you. That is a huge pet peeve of mine. Looking forward to next week’s episode, go get ‘em Brian!

#7: The Magic of Biodynamics (episode #26): Now this one is just plain weird! Adults in the 21st century actually believe that casting a magic spell over a vineyard will improve wine making. It’s just silly on so many levels, and it was another subject I had never heard of before. Just listening to Brian reading the “preparations” directly from a biodynamics website was hysterical. At the end of it, he says “It doesn’t say so but I think you’re supposed to chant Double double toil and trouble, fire burn and cauldron bubble while preparing it.” But I really cracked up when he was reading about why cow horns figure so prominently in the potion, complete with bongo drums, monkey and other animal sounds playing in the background. Priceless.

#6: Bend Over and Own Your Own Business (episode #95): Listen to this episode and just try not to laugh while he is naming off the various “business opportunities” companies are trying to sell. It reminds me of those stupid infomercials about “internet millions” that are on late at night. Um, okay, I only watch them because of the large breasted scantily clad women. It also reminded me of  Don Lapre, the infomercial jackass who used to try to sell you “his package” to make money by placing tiny ads in newspapers.  Apparently a lot of people fall for these type of scams. Brian’s description of how these so called opportunities take a normal sales job and invert it so you pay them to work for them was a lot of fun. He also mentions multi-level marketing, which is the king of the business scam. I am very much looking forward to a full episode about that. I really think it’s annoying when people ask if I am interested in a “business opportunity,” especially if it is to sell bogus “health” products like magic fruit juice.

#5: All of the episodes that specifically teach about critical thinking: Listen to these episodes if you want to become a better critical thinker: A Magical Journey through the Land of Logical Fallacies Part 1 and Part 2, How to Spot Pseudoscience, A Primer on Scientific Testing, How to be a Skeptic and Still Have Friends, and The Importance of Teaching Critical Thinking, in which Brian points out:

First of all, happiness and enlightenment are all around us in our world; they are not found only within a given pseudoscience. But moreover, once we begin investing our faith in unsubstantiated or supernatural phenomena, we are contributing to the redirection of attention, influence, and funding away from technologies and concepts that have been evidenced to be beneficial to humanity and to our world. As my good friend says: “If once you start down the dark path, forever will it dominate your destiny; consume you, it will.” The choice between pseudoscience and science is the choice between stagnation and progress: Progress toward long life, health, happiness, a cleaner planet, bountiful food, knowledge, and peace.

#4: The Detoxification Myth (episode #83): The idea that we need to “detoxify” our bodies has become ubiquitous in our society. Even at my work, I have known people who are very highly educated at top universities who go on “detox fasting diets” where they don’t eat and drink only water with lemon juice in it for a week. Some go and get “cleansing” colonic procedures. This episode is the second all time most discussed on the website, and it’s easy to see why. There are so many of these crazy detox ideas and so many people buy into them. One of the more stupid ones are the kinoki foot pads that are supposed to draw toxins out through your feet. The idea that your intestines get clogged with old fecal matter  is very popular. Just check out this crazy infomercial. These creepy guys are basically saying the we are all full of crap. I think they are. The government must not have all of the resources it needs to go after these charlatans, or they are letting them get by with disclaimers. The best defense you have against this kind of stuff is good information. If you have any friends or family members who are considering one of these detox scams, have them listen to this episode. Hopefully it can keep them from making a big mistake with their money and their health.

#3: New Age Energy (episode #1): The first episode is one of the very best. The word energy has been used and abused by so many new age, pseudo-scientific, and quack ideas that this episode kills a whole flock of birds with one stone. It’s simply an explanation of what energy is, and more importantly, what it is not. Energy is not a thing, it’s a measurement. If people can just get that concept they will be  better equipped not to fall for false health scams like straight chiropractic or acupuncture. Can somebody please explain it to Doctor Oz?

#2: Wheatgrass Juice (episode #6): Here is Brian’s reaction to a poster describing the benefits of wheatgrass juice: “My friends, the English language does not contain adequate hyperbole to do justice to the tons of manure printed on this poster.” Boy was he right. When I heard that they were claiming that the chlorophyll in it was “high in oxygen” I immediately thought wait…how can we get oxygen by ingesting it? That makes no sense. Then Brian said “it’s not true at all that chlorophyll is a good source of oxygen. I suggest you continue to rely on your lungs for that, which are probably better, since you don’t have leaves.” Brilliant, but it got better. They also claimed that the high magnesium content in it was good for your sex hormones. In fact, wheatgrass juice has hardly any magnesium at all. Brian then points out: “If you want magnesium, take a vitamin pill. If you want oxygen, take a breath. If you want sex hormones, get a girlfriend.” Just awesome. I am still waiting on an episode about bee pollen and extract of ginseng!

#1: When People Talk Backwards (episode #105): Alright, after 104 episodes I thought I had already heard all of the crazy I could take. But as Brian states in the beginning of this podcast “Just when you thought there was nobody in the world crazier than yourself, along come people who believe that we all subconsciously say what we really mean in reverse.” What? At first he goes into the description of what this means, and them goes on to describe the science behind the perception of what they think they are hearing: audio pareidolia. It was already interesting enough, but them came the audio samples. The first time I heard the sine wave sounds, it sounded like nothing to me. After I heard what it was supposed to sound like, I could not get my brain not to hear the speech! It was amazing. But my favorite moment had to be when he played the famous clip of Jim Morrison saying “Treasures there” backwards, which is supposed to sound like he says “I am Satan.” But then he plays the whole clip and it sounds more like he says “I am Sata-Schnigel.” Then, in his best sarcastic tone, Brian says “So if reverse speech is real, Jim Morrison’s true intention in life was to inform us that he’s Sata-Schnigel.” I was listening with my headphones at work at started cracking up so loud that people came around into my office to see what was going on. But the episode only gets better towards the end when Brian gives his own interpretation of an Indian music video. It was hilarious just to hear him say “I could be high today” and “I see the nuns are gay.” From beginning to end, this episode was just barrel of laughs.

So Brian is definitely right when he says we need to make skepticism commercial by making it entertaining. But the great thing is, he has already done that with the Skeptoid podcast. Hopefully, a television network will think the same thing about The Skeptologists. After all, if Oprah can make misinformation entertaining, why can’t we do the same with good information?

Oprah Winfrey Needs to Stop Promoting Pseudoscience Now

Posted by skeptologic on May 21, 2009

In the past, I have criticized Oprah Winfrey for her promotion of Doctor Mehmet Oz due to his support for pseudoscience and quackery. Keep in mind, I don’t like to criticize Oprah. She comes across as a very generous person who cares about people very much. She built a school in South Africa, gives people free cars and home makeovers, and sometimes does a lot of good by shining the spotlight on things that need attention. The problem I have with her is her promotion of pseudoscience. In addition to Doctor Oz, she has promoted psychic detectives, past life regression, many kinds of alternative medicine, “The Secret,” and many others forms of woo-woo. I’m sure in her mind she genuinely believes in these things and thinks they are wonderful. I just wish she would stop to consider the enormous harm that these beliefs can cause. But now, she has done something that has crossed the line. I am speaking of Oprah’s decision to give anti-vaccination advocate Jenny McCarthy her own show.

This is a public health hazard, it is irresponsible and dangerous. Thanks to vaccinations, children are now safe from many horrible deadly diseases that were common just a couple of generations ago. If enough people listen to Jenny McCarthy, children will die. It has already happened in the United Kingdom where a discredited study wrongly linked MMR vaccine with Autism. Consequently, there have been outbreaks of the measles in that country.  Ms. McCarthy is now claiming that she is not anti-vaccine, but I don’t believe her. If she was not against vaccines, she would not be out there spreading misinformation about them. She is now claiming that the vaccines are full of toxins, but her assertion is based on a lack of understanding that a high school chemistry class would easily cure. Contrary to what she says, vaccines do not contain ether, anti-freeze, or aborted human fetal tissue. Even though her claims have been debunked over and over, she still keeps repeating them. And she has stated herself in a recent interview with Time Magazine that “I do believe sadly it’s going to take some diseases coming back to realize that we need to change and develop vaccines that are safe. If the vaccine companies are not listening to us, it’s their f***ing fault that the diseases are coming back. They’re making a product that’s s***.  If you give us a safe vaccine, we’ll use it. It shouldn’t be polio versus autism.” There it is, she actually acknowledges that these diseases are going to come back. I wonder if she and Oprah Winfrey have really thought about what that means: the death of children.

Maybe to them those deaths are just statistics. I wonder if putting a human face on this travesty might help. You see, anti-vaccine propaganda in Australia has recently claimed the life of a four week old baby. Little Dana McCaffery was going to be vaccinated, but she was still too young. Her parents were unaware that the community they were living in had lost herd-immunity due to low vaccination rates for whooping cough. I want Jenny and Oprah to go to her website, read what happened, look at her picture and realize that she is not just a statistic. She was a person who spent her very short life suffering and gasping for air until she died. I myself saw this video on Phil Plait’s blog, and it has haunted me ever since. The anti-vaccination cranks in Australia actually sent them hate mail. What kind of a sick people send hate mail to a couple whose baby just died? Words fail me, they really do. Pseudoscience kills. For the sake of public health I really hope Oprah reconsiders her decision.

What it really means to be open minded

I love this great video explaining what it really means to be open minded and why skeptics who think scientificaly are more open minded that people who believe in the supernatural.

Hydroxycut – Another Example of why Congress Should Repeal DSHEA

Posted by skeptologic on May 2, 2009

As you have probably heard, the FDA has warned people not to use Hydroxycut products after several users of the product developed serious liver problems. Surprise, surprise, an an unregulated, untested, unapproved supplement is causing people harm. Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), any company or quack can come up with any bullshit product and sell it to the public without having to prove its safety or efficacy to anyone. As long as the claim it’s a supplement and it “is not intended to diagnose, treat, cure or prevent any disease” they can sell you snake oil, which is what most of these products are. They might as well sell them out of a wagon like they did in the old west. Most people think products like this are perfectly safe because the are “just supplements, not drugs” or because they are “herbal” or “all natural.” Wrong! Herbal supplements, all natural or not, are DRUGS. I always hear people criticizing the pharmaceutical companies for various reasons, but at least the pharmaceutical industry is practicing science. They have the burden of having to prove that the drugs they develop are safe and effective before the FDA will let them sell them. This process is not always perfect, but it’s better than nothing. I’ve said it before and I’ll say it again, if a company or person wants to make a medical claim about an herb or natural remedy they should have to prove that their product can do what they say it can do. And by proving it I do not mean a couple of clowns from their company giving the item to five people and asking them how they feel. I mean a real, double blind, placebo controlled clinical trial that is repeated by others and then submitted to the FDA. Billions of dollars a year are being wasted on useless products that at best just cost you some money, and at worst might take something much more valuable like oh, I don’t know…your liver! I again call on congress to take action and put the burden of scientific proof on everyone by repealing Dietary Supplement Health and Education Act of 1994. Let’s make the snake oil salesmen pack up their wagons and leave town.

A Graphic and Horrible Example of “The Harm”

Posted by skeptologic on November 19, 2008

“Those who can make you believe absurdities can make you commit atrocities.”

-Voltaire

The quote above is in my opinion one of the wisest things ever said. When people find out that I do not believe in the paranormal and am a vocal critic of such beliefs, I am often asked “Well, even if it (insert supernatural belief here) isn’t real, what is the harm in believing?” The answers to that question are varied depending on the specific nonsense under discussion, but today I came across one of the worst examples of how paranormal belief can cause suffering on a massive scale. It is particularly disturbing because it is happening against a group that is least able to defend themselves against it–children.

Imagine this scenario: A local religious leader tells you that your child is a witch who is possessed by Satan. They come into your house and for a steep fee that is usually more than you make in a year, begin a “deliverance ceremony.” The terrified child is then shaken violently, has “potions” poured into their eyes, and is dragged around the room. All of this while you the parent look on, praying that the ritual will work. If it does not, your child is then either killed, or thrown out of the house into the street to fend for themselves.  Sounds like something out of 14th century medieval times right? Nope, this is happening right now in Nigeria, where a blend Christianity and local tribal beliefs have created widespread fear of witchcraft. Many of the children are held captive in churches, chained up without food until they confess to being a witch. Just the thought of something even a fraction as terrible as this happening to my children makes me wince in horror.

Please read the article if you are one of those who think that beliefs in the paranormal are harmless. It goes without saying that if the people in these villages were not brainwashed by this nonsense, there is no way that they would allow this abuse of their children to happen, much less pay someone to do it. There are simply not enough words in the English language to describe how horrible these atrocities are, and what makes it even worse, is that all this abuse is FOR NOTHING. Nothing because witchcraft and Satan do not exist and never have. Think about it again: parents are paying people torture and kill their children due to a belief in something that can’t even be proved to exist.

If this is not sickening enough for you, or if you think that this is only an exception to the rule and that most supernatural, superstitious, paranormal, or pseudoscientific beliefs do no harm, please visit whatstheharm.net where you can see examples of how pretty much any of these beliefs can cause harm on a massive scale. And also keep in mind that I am writing this on the anniversary of another of the most graphic examples of how a lack of critical thinking can kill. It was thirty years ago today that 909 people, many of them children who had no choice in the matter, commited mass suicide in the cult community of Jonestown after being brainwashed into it by their cult leader, Jim Jones.
