Psychology Journal Bans Significance Testing
This is perhaps the first real crack in the wall for the almost-universal use of the null hypothesis significance testing procedure (NHSTP). The journal, Basic and Applied Social Psychology (BASP), has banned the use of NHSTP and related statistical procedures from their journal. They previously had stated that use of these statistical methods was no longer required but can be optional included....
Mel asks and I do my best to answer. On acupuncture.
I read a lot of the pseudo-medical websites. The writing is at best pedestrian, often turgid, and, at its worst, incoherent. It is rarely either engaging or clever. Wit, the clever bon mot, the amusing turn of phrase or retort, is rare at best. So rare I cannot think of an example. It is ironic that those who engage in fantastical treatments...
Chaperones Needed. On acupuncture.
I receive a monthly newsletter from my medical board. Among other issues discussed are the results of disciplinary actions for physicians. Occasionally a physician who has boundary issues is required to have a chaperone present when doing exams. I was thinking that the concept of a chaperone could be more widely applicable. Consider “You Docs: Amazing acupuncture,” the latest from Drs Oz...
Beware The P-Value
The p-value was meant to be used as a convenient and quick test to evaluate how likely a result was due to chance, or a real effect. It has since come to be treated as an indication of importance or truth, particularly in the CAM world. This is a problem.
Of the Trial to Assess Chelation Therapy, Bayes, the NIH, and Human Studies Ethics
An experiment is ethical or not at its inception; it does not become ethical post hoc—ends do not justify means. ~ Henry K. Beecher A couple of weeks ago, Dr. Josephine Briggs, the Director of the National Center for Complementary and Alternative Medicine (NCCAM), posted a short essay on the NCCAM Research Blog touting the results of the Trial to Assess Chelation...
What’s in a name?: NCCAM tries to polish a turd
What’s in a name? that which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call’d, Retain that dear perfection which he owes Without that title. Romeo, doff thy name, And for that name which is no part of thee Take all myself. William Shakespeare, Romeo and Juliet, Act II, Scene 2...
Osteopathy in the NICU: False Claims and False Dichotomies
I would like to preface this post by stating that I have worked with many DOs (Doctors of Osteopathy), and I have helped train many pediatric residents with DO degrees. I have found no difference in the overall quality of the training these students have received, and some of the very best clinicians I have ever worked with have been DOs. I...
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...
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...
A Skeptical Look at Screening Tests
Not all screening tests are worth taking. And in particular, some screening tests are worthless.
