Bittersweet Morning

Tuesday November 4th, 2008 was a milestone day in America. A day which saw us elect into office a new administration which promises to fix the mistakes and reverse the policies of the past eight years. That night I went to bed with a sense of optimism and hope about the next four years knowing that Barack Obama will be our new president. I am of course especially excited to have a president that is not going to be hostile to scientific inquiry. However, my optimism about my country was tempered the next morning by my disappointment with  my home state of California.  Wednesday morning I got the news that Proposition 8 (”Prop Hate”), a ballot initiative to ban marriages between homosexual couples, had passed by a narrow margin. I know this blog is about science and skepticism, and I usually try to steer clear of politics because it mostly involves value judgments and ideology rather than evidence. However I think it does apply here because Prop Hate was sponsored and motivated, as usual, by believers in the supernatural, in this case by religion.

The initiative was backed by money from evangelical Christians, the Catholic Church, the Mormon Church, and Islamic groups.  It is appalling to me how these religious groups, who have historically hated each other, can seem to only find common ground on one thing, more hatred. In this case it is their shared disdain for homosexuality. This insane preoccupation about what other people do while they are naked seems to be a common theme in all faiths. Why should I, a straight man, care so much about the rights of a group I don’t even belong to? I just can’t stand discrimination and I think it is time we ended it once and for all. Our society (most of it anyway) has slowly but surely been moving away from that stupid, outdated, and medieval concept. After all, we just elected our first African American president, and that is something to be proud of. Unfortunately, however, a large portion of our society seems to think that there are still some groups that are okay to discriminate against. Two of these groups are the non-religious and homosexuals. I am a member of the former and feel a kinship with the latter. We are both viewed by the religious majority as evil and immoral, gays because of the way they have sex, and secular people because we don’t believe in an invisible man in the sky. We are also both not immediately visible as a member of each group. We have to “come out of the closet” in order for people to know what we are. This can mean the risk of being ostracized by family, friends, or coworkers. And in some places it can even even lead to threats, physical violence, or loss of employment.

While this is a temporary setback for human rights, I think that eventually it will be overturned. The reason is that it goes against the highest law in the land, the United States Constitution. Allow me to quote from the first amendment of that great document:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof”

I think there is a reason that James Madison chose to make that the first line of the first amendment, even before our precious freedom of speech. He knew that if you let religion get control of the government and pass laws based on their beliefs, all of the other rights would be gone. Indeed this is what we do see every time in every theocracy around the world. To date, I have never heard an argument against homosexuality or homosexual marriage that isn’t either a logical fallacy or based entirely on religion. Because the denial of rights to a group of people is based on a religious belief, it violates the first amendment and is thus unconstitutional and illegal in the United States. Someday this will end up before the United States Supreme Court and should be struck down. The reason why we have a constitutional republic is because the founding fathers knew that sometimes the majority in a democracy can be as bad as a tyrannical dictator.

Separation of church and state is so important because it not only keeps those of us who do not believe free from religious dogma in our government, but it allows those who do believe to worship as they please without government intervention. Having the state recognize gay marriage does not mean that their churches will have to perform ceremonies for them or change their beliefs about homosexuals. They can all go on thinking what they do about them based on that line in Leviticus (I’ve often wondered why they are not trying to pass laws banning the consumption of shellfish, which is also prohibited in the bible) that they revere so fervently.  All it means is that same sex couples will be able to get a piece of paper from the state that grants them the same legal rights associated with marriage as everyone else.

Even though there are always setbacks, such as this proposition and the administration we have had in Washington for the last eight years, the overall trend is society has always been unmistakeably progressive. 150 years ago slavery was considered okay by most people, today it is considered as vile and reprehensible a thing as you can get. 100 years ago, women did not have the right to vote and there were many who did not want to grant it to them, today that would be unthinkable. And just 40 years ago in many places interracial marriage was still illegal (again because of religious beliefs), but now we are free to marry whomever we wish and the majority of people are fine with it. Back then, most were against it and used many of the same ludicrous arguments against it. The sign of the times moves on.

Even though I am not gay, I can sympathize with them because I can imagine how I would feel if people were to tell me that I could not marry the person I loved because of an old book that was written by primitive bronze age goat herders. So to the gay community I say keep fighting. Don’t ever give up until you have equal rights under the law. It may come slowly, but society will change and the type of thinking that led to the passing of this horrible proposition will be relegated to the scrap heap of history.

What a Crank!

A while back I had created a category called “Cranks and Nut jobs” in which to put people who could be classified as nothing but wacky. I had not written anything for that category yet and it seems fitting that the first person who gets the honor is Jack Thompson. Thompson, the Florida attorney who has made it his mission to blame everything that is wrong with the world on video games, has been recommended for enhanced disbarment by the Florida Bar. If this goes through he will be prohibited from applying to practice law again for 10 years. I say so long and good riddance.

Let me reveal my bias here right from the get go. I love video games. I have been an avid gamer since the very first time I dropped a quarter into an Asteroids game machine at a pizza place in the early 1980’s. I have owned most game consoles over the years and lots of PC games. Currently I play a lot of World of Warcraft when I get the chance. So I really take exception when this ambulance chaser runs around the county saying that violent crime is being caused by violent video games with absolutely no evidence to back up his claims. I would accuse him of confusing correlation with causation, but there simply is no correlation between violent video games and real world violence.

Thompson walked out of the June 4th hearing on the matter after the judge refused to let him read a statement of objection he had prepared. This “statement” does not sound like something written by a professional attorney, but rather like the rambling manifesto of a nut job living in a shack in the woods. Since his claims never had any merit I just wanted to say welcome to my blog Jack, you sir are a crank.

Here Be Dragons - More Excellent Stuff from Brian Dunning

A podcast, a web site, a book, a television pilot, and now a movie, is there anything Brian Dunning doesn’t do? On this blog, I most often write negative things about nutty people with crazy beliefs. It sure is nice to write an entry where I get to say nice things about someone. Brian’s free movie “Here Be Dragons: An Introduction to Critical Thinking” is now available for download and it is wonderful. He teaches critical thinking with the same great humor he always has on his podcast. I highly recommend this video to anyone who enjoys learning about science, critical thinking, and skepticism. You can watch it at www.herebedragonsmovie.com. I plan on spreading it around to everyone I can think of who needs a good slap of reality. Thanks again Brian, and keep up the good work.

The Not So Wonderful Wizard of Oz

I think it’s a little ironic that the category of woo that I used to be least interested in is the one I seem to be writing about most, so called “complimentary and alternative medicine” or CAM. Oh wait, let’s add supplements to that so we get a more suitable acronym: SCAM. Much better. Anyway, it has recently come to my attention that Dr. Mehmet Oz, a favorite on the Oprah Winfrey show, is going to get his own show. From what I have seen of him so far, I think this is a bad idea. Normally with out and out promoters of nonsense this is where I would start the name calling. However, I am going to stop short (barely) of calling Dr. Oz a quack.  I am sure he is a fine cardiothoracic surgeon and serves his patients well. My problem with Dr. Oz is that in addition to real medicine, he is a big promoter of non scientific medicine that is based on, well, crap.

I have seen Dr. Oz on the Oprah Winfrey show a couple of times and both times he made statements that were misleading and potentially harmful. On one episode a member of the audience asked him about having their feet massaged to relieve stress. Nothing wrong with that, it would have been fine for him to recommend a foot massage as a method of relaxation. However, instead of just telling the person to get a foot massage, he recommended a method of deep tissue massage known as Rolfing. A Google search of Rolfing quickly reveals tons of pseudo-scientific gibberish about how it is supposed to “align the human body with gravity” and can “restore energy flow.” It also leads people to other non evidence based “energy healing” modalities such as Reiki and Reflexology. So what is the problem with this? Nothing if all you want is a massage because it feels good, but many practitioners of these techniques claim that they can use them to actually cure serious diseases. If a person who is seriously ill avoids real medical treatment for one of these methods it can lead to their condition becoming worse or even to their death. By having a real doctor point a largely uncritical audience to these methods, it gives them an air of legitimacy that they don’t deserve.

On another episode, Dr. Oz recommended acupuncture to a woman who had pain in her shoulder. He sends her backstage for a treatment with an acupuncturist and (surprise surprise) when she comes back, she feels better. Many people watching this view it as a test that shows that acupuncture works. In order to test something like this properly, you would need a large group of people with similar symptoms. You would then need to divide them into two groups at random. One group would get so called “real” acupuncture where the practitioner inserts the needles where they should be inserted (acupuncturists believe there are what they call meridian points in the body) and another group would get sham acupuncture where the needles are inserted anywhere or are not inserted far enough. What is most important is that the study must be blinded so each group does not know what they are getting. Better yet, the test should be double blind so that neither the participants nor the person administering the test know which is which. Granted, this would be difficult to do with acupuncture, but some methods have been devised, such as having the needles inside of a sheath so the practitioner and patient don’t know if the needle is going in fully or not. These controls are important to filter out bias, the placebo effect, etc. Many studies have been done on acupuncture and other “energy healing” techniques and the all follow a similar pattern: The better designed the study is, the less of an effect there is and the best designed studies show no effect at all. Again, if all you are looking for is pain relief and you get a placebo effect from it there is nothing wrong with it. But right there on the show the acupuncturist, while giving Oprah herself a “wellness” treatment, claims that “Acupuncture treats any condition from allergies to, obviously, pain to gastrointestinal issues—a wide range of chronic diseases.” Telling people that sticking little needles into their skin can treat “any condition” and “a wide range of chronic diseases” is egregious, irresponsible, and dangerous.

Dr. Oz himself chimed in on the “science” of acupuncture and alternative medicine. The following quotes are taken directly from Oprah’s website:

“Here’s the irony—acupuncture has been around for 2,500 years in China,” Dr. Oz says. “There are a billion people in another part of the world who use these therapies.”

Here Dr. Oz makes logical fallacy of an appeal to ancient knowledge. Just because something has been around for 2,500 years does not necessarily make it valid. Just over a century ago in the west, before medicine became scientific, if you went to the doctor they would do something like try to bleed you with leeches in an effort to “balance your bodily humors.” I wouldn’t want 150 year old unscientific medicine performed on me, much less unscientific medicine from 2,500 years ago. When he states that a billion people use it, that is another fallacy known as argumentum ad populum or an appeal to popularity. How popular something is has no bearing whatsoever on whether it is true or not. Even if every person on the planet thought that one plus one equaled three, that would not make it true, one plus one would still equal two. It wouldn’t make any difference if six billion people liked acupuncture (or something else) and used it, that is not a criteria to judge its efficacy.

“But let’s broaden the discussion, because it’s not just about acupuncture,” Dr. Oz says. “The reason I’m so excited and passionate about alternative medicine is … [because it is] the globalization of medicine.”

Dr. Oz talks about his passion for alternative medicine, saying that it’s the “globalization of medicine,” presumably bringing together east and west. I don’t really like the term western medicine. It implies that where a particular treatment originated it what makes it real or better. The terms western medicine, Chinese medicine, Indian medicine, holistic medicine, alternative medicine, etc, are quite meaningless. This is not about one country or culture being better than the other. This is about whether or not the methods and treatments in question work, no matter where they come from. There is only scientific medicine which is based on evidence, and unscientific medicine which is based on superstition. There are plenty of unscientific medical methods that were made up in the west. Some examples are Homeopathy (Germany), Chiropractic (United States), and Iridology (Hungary). If any of these were to be scientifically proven, they would cease to be alternative and just be part of regular medicine.

Alternative medicines, Dr. Oz says, deal with the body’s energy—something that traditional Western medicine generally does not. “We’re beginning now to understand things that we know in our hearts are true but we could never measure,” he says. “As we get better at understanding how little we know about the body, we begin to realize that the next big frontier … in medicine is energy medicine. It’s not the mechanistic part of the joints moving. It’s not the chemistry of our body. It’s understanding for the first time how energy influences how we feel.”

I keep having to remind myself that this guy is a actually a medical doctor. Statements like that make me wonder if he ever cracked a science book in all those years of medical school. People who practice or promote unscientific healing techniques seem to think that energy is a substance. Their ideas center around “restoring the flow of energy”or “unblocking energy.” In this context the word energy is completely and utterly meaningless. Energy is not some kind of substance that can be manipulated to promote healing. Energy is a measurement of the capacity of something to perform work. In other words it is the potential or actual ability to move things. If Dr. Oz could prove or “measure” things like Chi, Prana, Auras, or any of the types of mystical “Life Force Energy” claimed in these practices, he would win the Nobel Prize for physics. Did he? Did I miss that news story? Of course not, it would major news because it would change everything we know about reality. Keep in mind here that energy is not something you measure, energy is itself a measurement of work. Sorry Dr. Oz but the next frontier in medicine is not “energy medicine” as you claim. Here’s a news flash for you: Metaphysical concepts such as vitalism were abandoned by medical science in the 19th century. You are over a century behind the times on that one.

In an ideal world, people like Dr. Steven Barrett, Dr. Steven Novella, or Dr. Mark Crislip would get their own television shows about the wonderful scientific medicine we have that has doubled our life expectancy in just the last century. As for Oz, just like in the movie, pay no attention to the man behind the curtain, the magic he is pushing is not what it’s cracked up to be.

The Chupacabra! Um, Wait…No. Just a Dead Dog

Tags: ,

A couple of days ago I came across this story. Every time I see a headline involving cryptozoology (Bigfoot, etc) I always hold out some hope that someone has finally found some shred of compelling evidence of one of these creatures. But it’s usually the same old hokey blurry videos of blurry blobs or anecdotal reports. In this case there was absolutely nothing, not even anecdotal evidence. The story is about a dead dog. Really, I’m not kidding, that’s it. Somebody’s dog died in Argentina and of course it gets blamed on a chupacabra. Man, if it isn’t one logical fallacy it’s always another. Here we have an argument from ignorance: My dog died, I don’t know how my dog died, therefore it must be a chupacabra! They are now attacking dogs instead of goats! Do we need to rename it the Chupaperro?

It’s really too bad. One of my favorite questions to ask my fellow skeptics (for fun) is if they could pick a paranormal belief and make it true which one would they pick. I’d personally like it if I could meet someone or something from another planet or if I could have superpowers of some kind. Now those things and most paranormal phenomena are pretty far fetched. But cryptozoology does not require as much of a stretch, it would simply be an animal we have not discovered yet. Let me be clear, I don’t believe in chupacabras, yetis, or lake monsters because there is no evidence. But if they were really out there and someone actually proved they existed (meaning they actually captured one) I’d be first in line at the zoo to see it, and I would be happy to be proven wrong because I would get to see such a fascinating creature. Unfortunately we get stories like this. A dead dog, whoop-de-doo.

The Dark Ages are Alive and Well

Here’s another story that made me think that it has to be a joke. A substitute teacher was fired for doing a magic trick. He made a toothpick disappear in front of the class and was accused of “Wizardry.” Someone needs to inform the administrators at this school of two things. Number one: Magic is not real. I can’t believe we actually have to point this out to adults in this day and age. And the second thing they need to be informed of is that the inquisition ended centuries ago.

How do you give a placebo to a city?

Just when you think you’ve seen it all, something else totally wacko shows up. I had to create a new category called “Weird Crap” just for stuff like this. Someone has decided to perform acupuncture on the city of Portland, Oregon. Check it out here. Acupuncture doesn’t really work on people, I don’t think it will work on a city either. After all, how are you supposed to give a city the placebo effect?!

My Journey to Skepticism

Today I’d like to talk a little bit about myself, specifically about why I am a skeptic and what led me to the skeptical movement. I was never really a big believer in the paranormal, but then again I never dismissed it either. I always had a healthy appreciation for science and history and I figured out that Santa Claus was not real at an early age. Most of the time I probably didn’t think about it much and thought there might be something to some of the claims, but I never paid it too much attention. I remember being very young and watching my uncle walk around our back yard with a forked stick looking for water (dowsing) and I figured there must be something to it because when they dug the hole, they found it. Little did I know at the time that there was water underground pretty much everywhere. I assumed that chiropractors were real doctors, Bigfoot might be out there somewhere, and took it for granted that UFOs might be alien spacecraft. As the years went by and I got older, I stopped believing in supernatural phenomena, with a mostly dismissive attitude towards it. I thought that was what a skeptic was, and I must admit that that did have a certain appeal. After all, I had heard there were still crazy people who believed the world was flat, that NASA had faked the moon landings, and in other such nonsense. I didn’t know who James Randi was until the late 1990’s, when I remember hearing that he was offering his million dollar challenge. I thought it was great that he was doing that, but didn’t look much further into it at the time. Then in 2003 I came across a little show on the Discovery Channel called Mythbusters.

You see, I grew up in the 70’s and 80’s and remember hearing the urban legend that Mikey from the Life Cereal commercials had died when his stomach had exploded from eating pop rocks and soda. I didn’t really think that one was true, but it was so much fun to see someone actually test it! On episode after episode, Adam and Jaime debunked myth after myth, many of which I had believed and that had been told to me by adults when I was growing up. That’s when I really got interested in weird beliefs and began searching the internet for more information. I was fascinated by why so many people could be taken in by these things. I would read James Randi’s commentary on his web site often, and found out there were wacky beliefs I had never even thought of. It was at this point that I learned the true meaning of what a skeptic was. A skeptic is not is a person who just dismisses things out of hand. I found out that skeptics were relatively open minded people who simply wanted proof through science, logic, and reason for whatever the claim was. An objective method to get to the truth no matter what it was, I liked that idea a lot.

A few years later I had a major change in my life that really pushed me to learn everything I could about logic and evidence through scientific skepticism: I became a parent. I now had the health and education of my children to think about, and that was not something I was going to take lightly. Suddenly the ability to find the truth about things mattered in a way that I had never thought would be so relevant. I wanted to be informed properly about any potential medical decisions I was going to have to make for them. I needed to learn how to really distinguish science from pseudoscience. It was also around this time that I discovered podcasts. I found Point of Inquiry, Skepticality, The Skeptics’ Guide to the Universe, and Skeptoid. Learning about a subject was never so fun and entertaining. I learned about critical thinking, logical fallacies, how to apply the scientific method, how people are fooled and fool themselves, and how a lack of critical thinking can be dangerous or even deadly.

It was nice to know that there were many more people out there like me. I like being a skeptic because, as Dr. Michael Shermer points out, it’s not a position. It does not rely on ideology, belief, tradition, or superstition. It does not push me towards any one side of the political spectrum. You’ll find weird unsupported beliefs on both sides and all the way in between. From the right wing religious fundamentalist who thinks people walked around with dinosaurs like Fred Flintstone, to the new age believer whose idea of medicine is getting his feet massaged while drinking wheatgrass juice and listening to Yanni. Skepticism can give you the tools you need to protect yourself and your family from quacks, frauds, and charlatans. It can save you time, money, and it can even save lives.

There are some people who criticize skeptics by accusing us of being party-poopers. They think we take the wonder out of life when we point out that the light in the sky is not a spaceship or that the log floating in the lake is not a monster. That the splotch of light in the photo is not a ghost or that we are not particularly special because the Earth is not at the center of the universe. But I don’t see it that way. I think there is so much grandeur to marvel at in the real universe that we live in. We could study it forever and never run out of amazing things, without ever having to invoke the supernatural.

So thanks to all of you in the skeptical community. Thank you to both the Mythbusters and Penn & Teller for your great television shows which bring skepticism to a broader audience than ever before. Thank you Dr. Novella and the Skeptical Rogues, Derek and Swoopy, DJ Grothe and the CFI, and Brian Dunning for doing your podcasts which have sharpened my critical thinking skills, entertained me so much, and allowed me to listen to the thoughts of so many great skeptics, especially James Randi and Dr. Michael Shermer. And a very special thanks to the late Dr. Carl Sagan for teaching so many the value of science and rational thought with unrivaled passion. I know sometimes it seems frustrating, but little by little you are all making the world a better place.

Pseudoscience on the Science Channel

Tags: , , ,

Last week, I criticized Walgreen’s for selling unscientific, untested supplements (Airborne and Homeopathy) in their store. It was particularly disturbing to see these items being sold in the legitimate pharmacy where I go when I need real medicine. Last night, I was disturbed to see pseudoscience on The Science Channel. It wasn’t one of their programs, but rather on a commercial during the program. The commercial was for Dr. Frank’s No Pain Spray. They claimed that the spray would cure pain from Arthritis, Stiffness, Fibromyalgia, Carpal Tunnel, and a lot more. The commercial was also littered with personal testimonials. The ability to cure multiple conditions and anecdotal evidence is what peddlers of pseudo-scientific crap use when there is no real evidence that their product works. But as it turns out, I didn’t even need these red flags to activate my Baloney Detection Kit (thank you Carl Sagan). Right away they tout it as “Dr. Frank’s Homeopathic joint and muscle pain relief.” Ah, homeopathy. I reserve the highest amount of ridicule for this type of alternative medicine. It’s bad enough that they are able to get away with selling people a small bottle of water as medicine for $19.95, but to see this promoted on the Science Channel was very very disheartening. Please watch the very entertaining video below of James Randi describing just how stupid homeopathy is. Oh, and by the way “Dr.” Frank, James Randi has $1,000,000 for you if you can prove your snake oil works. Not that you need it, I’m sure you’ve made much more than that by bilking plenty of people out of their hard earned money by selling them tiny bottles of water.

100% All Natural Nonsense

Posted April 25, 2008 by skeptologic
Categories: Alternative Medicine

Tags: , ,

As I’ve mentioned before, one of my pet peeves is the word natural when used to market products. The word seems to be everywhere these days. I see it on television commercials for food products, baby formula, soap, cosmetics, pretty much everything. As I walk down the aisle at the grocery store it is unavoidable on package after package. What it is about that word that makes every company want to slap it on their products? What exactly does it mean? I can understand if that means you would rather eat a peach off the tree instead of from a can, or if you want real blueberries in your muffin instead of an artificial thing that looks like a blueberry. However, I think the misuse and overuse of this word is causing some misconceptions in our society.

People seem to have the idea that if a product is natural that somehow that means that it can’t hurt you. In popular culture the words “all natural” have become synonymous with “perfectly safe.” This is simply not true. There are many things in nature that are very harmful and would not make good products for human consumption. I’ll throw out a few ideas. How about a skin cream made from poison oak. It’s all natural. Or a lotion made from the toxin of the Golden Poison Frog. One milligram of this poison is enough to kill 10 to 20 humans. It’s all natural. Anyone want to drink some mercury or eat some lead? They’re all natural. Anyone want a nasal spray loaded with the influenza virus? It’s all natural. There are countless plants, fungi, bacteria, viruses, and poisons found in nature that will kill you. Now of course I am not saying that every product being marketed as natural is unsafe, but just because something is natural should not give you a warm fuzzy feeling that whatever it is will not harm you.

So what exactly is the harm that this way of thinking can cause? A few years ago I read a new story about a teenage girl who nearly died after ingesting a plant that someone told her could get her high. I’ll never forget the quote from her in the report. She said something like “It was all natural so I didn’t think it would have any chemicals in it.” There sure is a lot wrong with that statement. It shows a frightening example of how a lack of basic science knowledge can be dangerous. Everything is made of chemicals, even us. Humans are mostly Hydrogen, Oxygen, Carbon, and Nitrogen, for example. Air is a chemical, and so is water, get the idea? What matters is if the chemicals in question are toxic or not. It makes no difference if the compounds are found in nature or created in a lab.

This misguided notion about natural being automatically better is what is leading many people to unproven alternative or naturopathic medicine. Bottom line: Herbs are drugs. There is nothing special about them that makes them safer or better than drugs that have been tested and approved by the FDA for safety and efficacy. If an herb contains a compound that can heal something, wouldn’t you rather be sure that you are getting the right dose? Wouldn’t you rather be sure that what is in on the label is exactly what is in the bottle? Wouldn’t you rather know about any potential side effects and drug interactions? The next time someone who is not a doctor offers you something as a potential cure and says not to worry because it’s “all natural,” just remind them “so is arsenic.”
