5 out of 4 Americans Do Not Understand Statistics

Ed: Doctors say he’s got a 50/50 chance at living.
Frank: Well there’s only a 10% chance of that
Naked Gun

There are several motivations for choosing a topic about which to write. One is to educate others about a topic about which I am expert. Another motivation is amusement; some posts I write solely for the glee I experience in deconstructing a particular piece of nonsense. Another motivation, and the one behind this entry, is to educate me.

I hope that the process of writing this entry will help me to better understand a topic with which I have always had difficulties: statistics. I took, and promptly dropped, statistics 4 times a college. Once they got past the bell shaped curve derived from flipping a coin I just could not wrap my head around the concepts presented. I think the odds are against me, but I am going to attempt, and likely fail, in discussing some aspects of statistics that I want to understand better. Or, as is more likely, learn for the umpteenth time, only to be forgotten or confused in the future. (more…)

Irritated by the Skeptical Inquirer. Again.

I have a confession. I have been interested in issues skeptical since high school when I came across a copy of the Zetetic at Powells. In the pre-digital era I had a complete library of Zetetic-Skeptical Inquirers (SI) that a decade ago was tossed in the recycle bin along with a similar collection of MacWorlds. I have been interested in skepticism a long time and, here is my confession, I no longer find much of the subject matter covered by SI all that interesting. Even big ticket topics like the existence of God are uninteresting. It is not that the topics are not important, they are, and each generation has to relearn why Bigfoot or haunted houses or UFO’s are nonsense. But for me it is a large serving of been-there, done-that.

So while I subscribe to SI, it is more from a sense of obligation to support institutions I think are important than from an expectation that I will be either educated by the content or entertained by the style of the writers. I usually skim the magazine while accomplishing tasks that do not require my full attention probably because SI is the only magazine I still receive in dead tree format, the rest of my life being digital.

So I ran across “Taking our medicine: What hope for skepticism in healthcare?” by Kenneth W. Krause and after skimming it I was irritated. So I read it again and I was more irritated, which is often a good sign. But I could not quite put a finger on what it was. So I read it again and then went for a walk and thought about it.

All the facts were fine. I had no issue with the content of the article. It was the adjectives that irritated me. And the essay was, from my perspective, incomplete. It was like reading a relationship/birth control article by the Pope. Sure, he knows the facts of the situation, but not being an active participant in the process and with an agenda to promote, vital information will be missing or distorted. (more…)

Alternative Microbiology

A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science.

~ Claude Bernard.

I almost never have to search for material for this blog. The Secret always seems to provide topics. Subject matter appears unbidden out of the ether. But not this week. I enjoy deconstructing the nonsense of SCAM papers or blog entries more than any other type of blog entry. Perhaps the glee that last week’s entry provided had to be countered by some kind of cosmic balancing mechanism. Although the rational part of my mind objects to the personification of random existence, I suppose the Universe just does not want me to have that much fun two entries in a row. Probably explains why I have a viral URI and my brain has slowed almost to the point of functional inactivity. There is no shortage of SCAMs to write about, they are just not created equal in their ability to generate a passionate rant. (more…)

Scam Stud

We have evolved in order to survive reality, not to understand it. And it is a good thing that understanding and survival are not tightly linked as many people are apparently totally disconnected from the reality I inhabit, the one described by the natural sciences. When I started writing and podcasting about the SCAMverse I was under the impression that people who used SCAMs were simply misinformed. If people were made aware of the facts of the matter, they would see the error of their ways and put away their SCAMs as the childish thoughts they are.

Silly me. Reality, as I understand it, is often if little interest to proponents of SCAM. This was brought home by the Food Babe with an essay Should I get the Flu Shot? Spoiler alert. Her answer is “No, I’m not taking the Flu Shot. Ever.”

It is how she reaches that conclusion that is amazing. There are nouns and adjectives and adverbs and verbs and article and prepositions. They are strung together to form sentences and paragraphs, but somehow, though an almost magical alchemy, all that writing transmutes into content that is completely divorced from reality as I understand it. It is a tour de farce that reaches the definition of the Pauli Principle, where “It is not only not right, it is not even wrong.” (more…)

Pump it up: osteopathic manipulation and influenza

First, my bias. I work in Portland and we have medical students, residents, and faculty who are DOs (Doctor of Osteopathy). Before he moved on to be a hospitalist my primary physician was a DO. From my experience there is no difference between an MD and a DO. In my world they are interchangeable. There are many more qualified applicants for medical education than positions in MD programs and some opt for a DO education. Osteopathy has a dark side.
As best I can determine from my colleagues, learning osteopathic manipulation (OM) is the price they pay to obtain an otherwise standard medical education. I have yet to see OM offered by any of my DO colleagues. It may be they know better than to offer such a modality around me given my ranty propensity for all things SCAM.

The literature would suggest that OM is left behind by most DOs upon graduation. DOs are not proud of their OM, and rarely invite them ‘round to dinner. It will be interesting to see if OM fades over time in DO school as the old time true believers die off and are supplanted by a generation of DOs trained with more traditional medical education.

OM, the small pseudoscientific aspect of DO medical school education, is a form of massage and manipulation invented in the 19th century with no basis in reality. OM postulates

the existence of a myofascial continuity – a tissue layer that interlinks all parts of the body. By manipulating the bones and muscles of a patient a practitioner is supposed to be able to diagnose and treat and variety of systemic human ailments.

Studies into the efficacy of OM find it to be ineffective for any process aside from low back pain (is there anything that does not help low back pain?), not surprising for a therapeutic intervention detached from reality. My purpose with this entry is not to review OM per se, which may be a good topic someday, but to focus on a specific application of OM. (more…)

What are words for?

Do you hear me

Do you care

Do you hear me

Do you care

My lips are moving and the sound’s coming out

The words are audible but I have my doubts

That you realize what has been said

You look at me as if you’re in a daze

It’s like the feeling at the end of the page

When you realize you don’t know what you just read

What are words for when no one listens anymore

What are words for when no one listens

What are words for when no one listens it’s no use talking at all

I might as well go up and talk to a wall

‘Cause all the words are having no effect at all

Missing Persons on blogging. Or so I thought. I was surprised to learn the song was written by the brothers Gibb.

Words are important. I try and choose my words carefully when writing so that they accurately reflect not only my thoughts but reality. When I speak, not so much. My frontal lobe filters often fail if I think might I might get a laugh.

I tell housestaff, precision of writing reflects precision of thought. It is one of the reasons I write; the act of writing forces some coherence into what can be muddled and inchoate thoughts. Even though I have residents who write notes, I always write my own. Often I do not make a final decision as to a plan until I put pen to paper, or electrons to screen. Writing crystallizes thought.

Not, evidently, for everyone, as 10 Facts About the Flu Vaccine and the Flu nicely demonstrates. (more…)

I refute it thus

Reality is one honey badger. It don’t care. About you, about your thoughts, about your needs, about your beliefs. You can reject reality and substitute your own, but reality will roll on, eventually crushing you even as you refuse to dodge it. The best you can hope for is to play by reality’s rules and use them to your benefit. Combined with a little luck (nothing quite as beneficial as being a white, middle class male in the US) you might have a reasonably healthy health.

The most reliable way to understand reality is science and the scientific method. Used wisely you may have a shot at minimizing morbidity and mortality. Deny or ignore it and reality don’t care. Reality will get us all.

We all have our biases, recognized and unrecognized. I often see the world in terms of infectious diseases. When I read Team of Rivals: The Political Genius of Abraham Lincoln I enjoyed the politics and personalities but I was struck by how people constantly died young of infectious diseases. We don’t see mortality in the young anymore for a variety of reasons: better nutrition, an understanding of the pathogenesis of disease, clean water, flush toilets and vaccines.

Survey Says…

Surveys are evidently a popular way to get a paper published. Put “complementary alternative medicine survey” into Pubmed and get 2,353 hits. I would have trouble coming up with a hundred groups about whom I would be interested in their use of SCAMs, but I tend to be a lumper rather than a splitter. But if you want to know about SCAM use in chronic pain patients in one Singapore hospital, the information is available.

I am a survey magnet and a remarkable number of people send me dead tree and electronic surveys which I generally ignore. So people like me, those who ignore surveys (but support public television), are underrepresented in surveys. But evidently there is no group whose attitudes about SCAM are not amenable to analysis including my medical brethren, Infectious Disease doctors.

So I was understandably curious when I was sent a link to “Infectious Diseases Physicians’ Attitudes and Practices Related to Complementary and Integrative Medicine: Results of a National Survey“. The abstract makes it sound like my colleagues are a bunch of ignorant rubes who just fell off the turnip truck: (more…)
