From the author’s website: “Shameless use of cute baby to promote book”
When a baby is born, parents are often awed and alarmed to find themselves responsible for this tiny new person, and they desperately want to do their very best to keep their infant safe and healthy. New mothers worry about everything from SIDS to vaccines, from feeding practices to sleep hygiene, and they are bombarded with conflicting advice about caring for their babies. Myths and misinformation abound. Finally someone has written a truly science-based guide to the first year of life: The Science of Mom. The author, Alice Callahan, is a research scientist with a PhD in nutritional biology. When her first child was born, she had a lot of questions, and thanks to her background she knew how to look for reliable answers in the scientific literature. She started writing the Science of Mom blog and eventually turned her findings into a book.
Her first chapter covers the important concepts for understanding how to think about scientific studies:
- Good science is a process that takes lots of experiments, time, and people.
- Good science is peer-reviewed.
- One study on its own isn’t worth much, but scientific consensus is trustworthy.
- Some studies are more valuable than others (here she covers the various types of study from animal studies through observational studies in humans to RCTs and meta-analyses).
- Numbers matter (sample sizes).
- Don’t believe everything you read on the Internet (here she gives some practical tips for evaluating whether a website is reliable).
- Correlation is not causation (she uses my favorite example of the correlation between autism diagnoses and the sales of organic food).
- We can’t eliminate risks (but science can quantify the risks and benefits and families can use the information to decide what risks they are personally willing to take).
- Find smart allies (experts and providers you can trust).
- Forget about perfection and pay attention to your baby.
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
– Shakespeare’s Macbeth, Act 5, Scene 5
“Vaccine Whistleblower”? More like the next Andrew Wakefield in the making, albeit a shy, really pissed off Andrew Wakefield.
I don’t review books that often. The reason is simple. My posts for this blog sometimes take as much as a several hours to write (particularly my more “epic” ones that surpass 5,000 words), and I usually don’t have the time to add several more hours to the task by reading an entire book. Also, by the time I’ve read a book I might want to review, weeks—or even months—have often passed, and a review is no longer of much interest to our readers anyway. Fortunately, Harriet does an admirable job of reviewing books for us.
Today, I’m making an exception for a book hot off the presses. The main reason is curiosity, because the book is about a topic that I’ve blogged about three times here and several times more for my not-so-super-secret other blog, and I really wanted to find out more about what was going on. I didn’t expect to find out what really happened, because I knew from the beginning that the book, Vaccine Whistleblower: Exposing Research Fraud at the CDC by an antivaccine lawyer named Kevin Barry, would be highly biased. However, as I found out a few weeks ago, the book promised four complete transcripts of telephone conversations between the “CDC whistleblower,” a Centers for Disease Control and Prevention (CDC) psychologist named William W. Thompson who has been a co-investigator on important CDC studies since the late 1990s.
Given my rather public skepticism about the particulars of Thompson’s story, I was quite surprised when my request to Barry’s publicist for a review copy of Vaccine Whistleblower was enthusiastically answered in the affirmative, thus giving me time to read the e-book before it was released. I also sent a copy of the book to a law professor familiar with the saga, Dorit Reiss, to write a legal perspective (also being published on SBM today) which is why I will say little about this aspect of the book in my discussion. In addition, René Najera has examined the book from a statisticians’ standpoint.
“Dr. Joe” (from the title of his radio show) has done it again. He keeps putting out books faster than I can take them in; this one is titled Monkeys, Myths, and Molecules. It is packed with pithy analyses of health-related subjects that should be of particular interest to SBM readers.
Dr. Joe is Joseph Schwarcz, a chemistry professor and science popularizer based at McGill University. I’ve reviewed two of his many previous books before, Is that a Fact? here on SBM and The Right Chemistry over at Skeptic.com, as well as his free online chemistry lectures, “Food for Thought“, over at edX.org. As usual, this new book is a compendium of short (four-page) articles on a variety of subjects, written in a humorous, accessible style, and larded with intriguing trivia like where to see the largest illuminated advertising sign in the world.
If you read this book, you will:
- Learn that Mozart only had seven teeth when he died.
- Learn what was the first synthetic drug ever given to a human, and who administered it.
- Learn that Popeye really ate spinach for the vitamin A, not for the iron, and how myths about myths about spinach (no, that’s not a typo) led to ever-increasing misinformation.
- Hear the story of American military experts in WWII who had the bright idea of turning bats into weapons by attaching small incendiary devices to them. In an experiment hilariously gone wrong, the flaming bats set fire to a general’s car. (Remember that saying about military intelligence?)
- Learn the role of coprolites (fossilized animal poop) in the development of modern agriculture.
- Learn why Greek yogurt is not friendly to the environment.
Dr. Joe is a packrat for tidbits like these. I wonder where he finds them all. He seems to have a bottomless supply. (more…)
You can lead a true believer to facts, but can you make him think?
I got an e-mail with a link to a video featuring “Dr.” Leonard Coldwell, a naturopath who has been characterized on RationalWiki as a scammer and all-round mountebank. Here are just a few examples of his claims in that video:
- Every cancer can be cured in 2-16 weeks.
- The second you are alkaline, the cancer already stops. A pH of 7.36 is ideal; 7.5 is best during the healing phase. [We are all alkaline. Normal pH is 7.35-7.45.]
- IV vitamin C makes tumors disappear in a couple of days.
- Very often table salt is 1/3 glass, 1/3 sand, and 1/3 salt. The glass and sand scratch the lining of the arteries, they bleed, and cholesterol is deposited there to stop the bleeding.
- Patients in burn units get 20-25 hard-boiled eggs a day because only cholesterol can rebuild healthy cells; 87% of a cell is built on cholesterol.
- Medical doctors have the shortest lifespan: 56. [Actually they live longer than average.]
My correspondent recognized that this video was dangerous charlatanism that could lead to harm for vulnerable patients. He called it a “train wreck, with fantasy piled upon idiocy.” His question was about the best way to convince someone that it was insane. He said, “If you could rely on someone to follow and understand basic information about the relevant claims, it would be a gimme. But to the casual disinterested observer, who can interpret the whole video as ‘Well, he just wants people to eat right,’ pointing out the individual bits of lunacy just looks like so much negativity.”
He asked, “How do I best represent what’s happening to someone who is either a) emotionally invested in this and/or b) casually approving of it? … I just want to be patient, not shout anyone down, not make anyone defensive, and then win. Very surprised I don’t already know how. But I feel like I don’t. What is the psychologically sophisticated approach to this?” (more…)
We’re all going to die, but we don’t like to think about it. I’ll reach the proverbial threescore years and ten next month, so I’ve been thinking more about it, wishing I knew some reliable way to ensure that I would live many more years and remain fully functional until I suddenly collapsed like the Deacon’s wonderful one-hoss shay. There are myriad “longevity clinics” and “anti-aging” formulas, and every centenarian has an explanation that is the direct opposite of some other centenarian’s explanation. But what does the scientific evidence say? In his new book Spring Chicken: Stay Young Forever (Or Die Trying), Bill Gifford has done us a great service by investigating the latest scientific evidence about aging and presenting his findings in an engaging narrative form. He interviews some of the major players and introduces us to health fanatics who are convinced they can prolong their lives by doing things like monitoring their own blood cholesterol levels on a weekly basis, exercising obsessively, severely restricting their calorie intake, fasting intermittently, deliberately exposing themselves to stress like swimming in icy water, competing in extreme athletics, taking boatloads of hormones and supplements, experimenting on themselves with investigational drugs, and doing other questionable and sometimes bizarre things.
Are there limits to human life expectancy?
There is no documented case of anyone living longer than Jeanne Calment of France, who died at the age of 122. Jay Olshansky thinks biological forces limit how long we can live. Aubrey de Grey thinks some people alive today will live to be a thousand years old. Gifford explains the controversy and the reasoning behind both sides. Will we someday be able to re-engineer human biology to overcome the limits? The jury is still out. (more…)
Ron Rosedale, MD has devised a “powerful program based on the new science of leptin.” “Finally — the ultimate diet for fast, safe weight loss, lifelong health, and longer life…” He suggests it will prevent or improve high blood pressure, diabetes, heart disease, osteoporosis, arthritis, and a host of other ills. He repeats the CAM canard that “doctors only treat symptoms” and claims that his diet corrects the underlying cause of obesity, premature aging, and many diseases. That underlying cause is hormone (leptin) dysfunction. His is essentially just another low carb diet, only with more fat and less protein than other versions. His recommendations are ridiculously elaborate and are not supported by good evidence. His diet extrapolates from basic science, is based on speculative hypotheses, and has never been tested to see whether it works and is safe, much less whether it is superior to other diets.
If this sounds vaguely familiar, it should. He is doing what so many proponents of fad diets have done in the past, and he does it poorly. His book is a puerile effort compared to Gary Taubes‘ Good Calories, Bad Calories; Taubes at least marshaled an impressive mass of scientific data, presented a cogent argument, and ultimately acknowledged that more studies would be needed to test his recommendations.

Despite all those Polish jokes, Poland has its share of good scientists and critical thinkers. A superb new book illustrates that fact in spades:
Psychology Gone Wrong: The Dark Side of Science and Therapy, by Tomasz Witkowski and Maciej Zatonski, Witkowski is a psychologist, science writer, and founder of the Polish Skeptics Club; Zatonski is a surgeon and researcher known for debunking unscientific therapies and claims in clinical medicine. Together, they turn a spotlight on research and treatment in the field of psychology. They uncover distressing flaws, show that many commonly accepted psychological principles are based on myths, argue that psychotherapy is a business and a kind of prostitution rather than an effective evidence-based medical treatment, and question whether psychotherapy should even exist, since in most cases it offers no advantage over talking to a friend about one’s problems, and in some cases can cause harm.

Note: I wrote two posts today to alert readers to two upcoming television events in time for them to plan their viewing. See the second post for an announcement about a film on scientology, along with an article about Scientology’s War on Medicine that I wrote for Skeptic magazine.
Filmmaker Ken Burns
Ken Burns has made a lot of outstanding films. His The Civil War has been listed as second only to Nanook of the North as the most influential documentary of all time. I was delighted to learn that he had applied his exceptional skills to a topic that is very important to us on the Science-Based medicine blog, cancer. His film is based on the Pulitzer Prize-winning book by Siddhartha Mukherjee, The Emperor of all Maladies: A Biography of Cancer.
I reviewed Mukherjee’s book in 2010. He is an oncologist and cancer researcher and also a superb writer. I characterized his book as:
a unique combination of insightful history, cutting edge science reporting, and vivid stories about the individuals involved: the scientists, the activists, the doctors, and the patients. It is also the story of science itself: how the scientific method works and how it developed, how we learned to randomize, do controlled trials, get informed consent, use statistics appropriately, and how science can go wrong.
I continue to think it is the best book ever written on cancer.
The film interviews Mukherjee and many of the researchers and patients whose stories appear in the book. If you haven’t read the book, it will give you an idea what it’s about. If you have read the book, you will enjoy it even more as you meet the people you have read about. It covers the history of cancer as well as the most recent scientific developments and is very optimistic about the future.
The movie is scheduled to premiere March 30 – April 1 at 9 PM EST on PBS, in 3 parts with a total duration of 6 hours. You can watch the trailer online. The producers sent me a press preview 1-hour highlight reel and I was very impressed. I can’t wait to watch the whole thing. I hope you will be able to watch it too.
Note: The film Going Clear: Scientology and the Prison of Belief will be available on HBO starting March 29th. I haven’t seen it yet, but apparently it profiles former members who reveal details that have elicited a very angry response from the Church of Scientology. I thought I would use the occasion to reprint a SkepDoc column that originally appeared in Skeptic magazine (Volume 18: Number 3) titled “Scientology’s War on Medicine.”
Scientology has openly declared war on psychiatry and is ambivalent if not openly hostile towards the rest of medicine. Its “mind over matter” philosophy promises that attaining the “Clear” state will eliminate illness.
Recently there has been a spate of exposés of Scientology, ably reviewed by Jim Lippard on eSkeptic. They offer some shocking revelations. Defectors from Scientology have described kidnappings, deliberate lying, unnecessary deaths, human trafficking, thought control (“brainwashing”), coercion, violations of labor standards, violations of human and civil rights, and other crimes. Scientology has been protected from prosecution by its designation as a religion and its vast wealth and influence; but if even a fraction of these accusations are true, Scientology has much to answer for.
Initially people are attracted to Scientology because it provides answers. Your problems are due to past experiences holding you back. Scientology can help you deal with those problems and the upper levels will reveal the secret of life itself.
Members are audited with an E-Meter (similar to a lie detector) and one-on-one attention. The auditing process is similar to psychotherapy in that it encourages people to think about their problems and work to overcome them. In Scientology, ideas are not immaterial: they have weight and solidity. The E-Meter locates and discharges mental masses that are blocking the free flow of energy. Memories are blamed and traced back in time even into past lives. Patients keep repeating the details of the experience until they are drained of any emotional charge. Once the painful experiences and associations are drained off, there are astonishing results: asthma, headaches, arthritis, menstrual cramps, astigmatism, and ulcers simply disappear. The reactive mind is replaced by the rational mind. In one case a boy’s IQ supposedly rose from 83 to 212. (more…)
In 2008 I wrote about neuroplasticity as presented in Norman Doidge’s book The Brain That Changes Itself. I urge you to click on the link and read what I wrote there before you continue. The science is fascinating. The brain is far more malleable than we once thought. Areas of the cortex devoted to a sensory input shrink when that input is lost. Neurons from other parts of the brain can be co-opted to take over lost functions. Learning a new skill actually changes the structure and function of the brain: the areas of the cortex devoted to that skill enlarge as the new skill is practiced and perfected.
This is exciting stuff, with potential therapeutic applications in chronic pain, brain damage, and chronic illness. When I reviewed that book, I said I thought Doidge was a bit overenthusiastic; and now he has written a follow-up book that is even more overenthusiastic. In The Brain’s Way of Healing: Stories of Remarkable Recoveries from the Frontiers of Neuroplasticity, he slips into unscientific speculations and relies on anecdotes about patients who have allegedly benefited from practical applications of brain plasticity science. The title is accurate: these are stories, not scientific studies. I continue to find the subject fascinating and to believe that neuroplasticity offers a lot of potential for human healing, but I don’t believe we have learned much about practical ways to accomplish that. Doidge’s book goes beyond the science. (more…)
