Where Is The Worst Health Information On The Internet? The Huffington Post

Going to the Huffington Post for medical information is perhaps comparable to going to Vito Corleone for advice on income tax compliance.  Another prominent blogger refers to is as “that hive of scum and quackery,” a lovely and accurate epithet for a media outlet which provides refuge and cover for anti-vaccationists, homeopaths and practictioners of reiki and other such pseudoscientific twaddle. I avoid the HuffPo like the plague.  But, like a moth to the flame, sometimes I can’t help myself, and when a facebook friend (and former blogger) pointed to this contrarian article, my interest was piqued and I had to check it out.

Is High Blood Pressure Overtreated? Dr. Dennis Gottfried, Associate professor, University of Connecticut Medical School

First of all, I don’t know Dr Gottfried, and I don’t want to cast aspersions on him professionally. He might be a faith healer and snake-handler, or he might be a prominent researcher and expert in the field. I have no idea, and other than his questionable judgement in being affiliated with the HuffPo, I don’t want to make any judgement on him as a physician or a scientist. Read more »

Bad Science And The Gift Of Medical Skepticism

Discover magazine had an article about Dr. Ben Goldacre, a British physician who writes for The Guardian, is the author of the new book “Bad Science: Quacks, Hacks, and Big Pharma Flacks,” and is considered a gift to skepticism. His column is also called “Bad Science,” and he recently gave a short and interesting talk about non-evidence-based medicine at the Pop!Tech conference held in Camden, Maine. Enjoy!

Health And Medicine: Scientific Or Miraculous?

I was recently listening to an audiobook about diet, written and read by a “famous” doctor who gets people healthy through dietary changes.

Since my podcast pushes me a little into the mainstream (more than this blog does), I thought it would be good to hear what the “average” person is reading about health. Plus, I am not exactly the most compliant patient when it comes to diet, so I thought I could possibly get something out of it personally.

I did my best to listen with an open mind, ignoring what I thought were gimmicks and trying to glean the valuable information from what this doctor was saying.

I had to stop, however, before finishing the book. It wasn’t the content so much that gave me cause to feel the desire to smash my iPod, it was the hype. The author was constantly using words like “amazing,” “magical,” and “miraculous.” Read more »

When “Big Pharma” Is Demonized

To be blunt up front –- SBM is not apologetic about the pharmaceutical industry. We get zero funding from any company, and have no ties of any kind to “big pharma.” In today’s world I have to spend time making that clear, because despite the reality critics are free to assume and falsely claim that our message is coming straight from the bowels of hell (a.k.a. the pharmaceutical industry).

We promote science-based medicine and criticize pharmaceutical companies along with everyone else when they place other concerns ahead of scientific validity, or promote bad science, for whatever reason.

It has become fashionable, however, to not only criticize the pharmaceutical industry but to demonize them –- and the term “big pharma” has come to represent this demonization. Cynicism is a cheap imitation of skepticism –- it is the assumption of the worst, without careful thought or any hint of fairness. Read more »

Bad Science: Nine Ways To Dress Up Flawed Research

This post is a follow up to my book review of Bad Science, located here.


I couldn’t help but feel unusually depressed by Dr. Ben Goldacre’s exposé of researchers who resort to trickery to get their articles published in peer-reviewed journals. There are a number of ways to manipulate data and many ways that flawed research is presented to enhance its chances of publication.

Before we get started, I need to point out that “negative trials” – or research results that don’t corroborate the investigator’s original hypothesis/es – are much less likely to be published. People (and/or publishers) are far more interested in finding a needle in a haystack, than hearing that no needle could be found.  This is a driving force in all manner of mathematical convolutions aimed at demonstrating something interesting and to warrant publication. After all, who can blame the researchers for wanting to get their research published, and to have it make a meaningful contribution to their field of study? Who wants to toil for months to years on end, only to discover that their hypotheses were not born out by experimentation, and in fact no helpful conclusions may be drawn whatsoever?

And so, with this intense pressure to find something meaningful in one’s research (either for profit or personal satisfaction and professional advancement) – there are some typical stragegies that researchers use to make something out of nothing. Ben Goldacre reviews these strategies in the voice of an unscrupulous senior pharmaceutical investigator, giving advice to his junior colleague. (Parenthetically, it reminded me of The Screwtape Letters – an amusing book written by C.S. Lewis, featuring the imaginary advice of a senior demon to his junior counterpart as they tempt humans to evil.)

(This passage is taken directly from pages 192-193 of Bad Science)

1. Ignore the protocol entirely. Always assume that any correlation proves causation. Throw all your data into a spreadsheet programme and report – as significant – any relationship between anything and everything if it helps your case. If you measure enough, some things are bound to be positive by sheer luck.

2. Play with the baseline. Sometimes, when you start a trial, quite by chance the treatment group is already doing better than the placebo group. If so, then leave it like that. If, on the other hand, the placebo group is already doing better than the treatment group at the start, then adjust for the baseline in your analysis.

3. Ignore dropouts. People who drop out of trials are statistically much more likely to have done badly, and much more likely to have had side effects. They will only make your drug look bad. So ignore them, make no attempt to chase them up, do not include them in your final analysis.

4. Clean up the data. Look at your graphs. There will be some anomalous ‘outliers,’ or points which lie a long way from the others. If they are making your drug look bad, just delete them. But if they are helping your drug look good, even if they seem to be spurious results, leave them in.

5. The best of five… no… seven… no… nine! If the difference between your drug and placebo becomes significant four and a half months into a six-month trial, stop the trial immediately and start writing up the results: things might get less impressive if you carry on. Alternatively, if at six months the results are ‘nearly significant,’ extend the trial by another three months.

6. Torture the data. If your results are bad, ask the computer to go back and see if any particular subgroups behaved differently. You might find that your drug works very well in Chinese women aged fifty-two to sixty-one. ‘Torture the data and it will conhfess to anything’ as they say at Guantanamo Bay.

7. Try every button on the computer. If you’re really desperate, and analysing your data the way you planned doesn’t give you the results you wanted, just run the figures through a wide selection of other statistical tests, even if they are entirely inappropriate, at random.

8. Publish wisely. If you have a good trial, publish it in the biggest journal you can possibly manage. If you have a positive trial, but it was a completely unfair test, then put it in an obscure journal… and hope that readers are not attentive enough to read beyond the abstract to recognize its flaws.

9. Do not publish. If your finding is really embarrassing, hide it away somewhere and cite ‘data on file.’ Nobody will know the methods, and it will only be noticed if someone comes pestering you for the data to do a systematic review. Hopefully that won’t be for ages.

Eat To Save Your Life: Another Half-True Diet Book
