Treating Migraines
I am a headache specialist and so I receive many questions, through SBM, NeuroLogica or listeners of the Skeptic’s Guide to the Universe, about how to best treat headaches, or about a specific, often unusual, treatment. Migraines and severe headaches are very common. According to the latest statistics: 14.2% of US adults 18 or older reported having migraine or severe headache in...
Unfalsifiable Beliefs
As we search for a logo for SBM or the SfSBM, Mark Crislip has been a strong advocate of using an image of Sisyphus, endlessly pushing a boulder up a hill only to have it roll back down again. It’s a bit too self-defeating to be enthusiastic about that suggestion, but it does reflect a common feeling among all of us here...
Acupuncture, Organic Food, and Other Questions
In this post I respond to some reader mail regarding several different issues - organic farming and pesticides, acupuncture, and herbal supplements. In each case I clarify my position and discuss the evidence base.
Neuroscience and Destiny
A newly-published review of neuroscience research looking at the predictive value of functional and anatomical imaging raises interesting questions about the role of such studies in learning, psychiatric treatment, and even the treatment of criminals. “Prediction as a Humanitarian and Pragmatic Contribution from Human Cognitive Neuroscience” by Gabrieli, Ghosh, and Whitfield-Gabrieli and published in Neuron, does a thorough job of explaining the...
Glyphosate – The New Bogeyman
There is an ideological subculture that is motivated to blame all the perceived ills of the world on environmental factors and corporate/government malfeasance. Often this serves a deeper ideological drive, which can be anti-vaccine, extreme environmentalism, or anti-GMO. The latest environmental bogeyman making the rounds is glyphosate, which is being blamed for (you guessed it) autism. Glyphosate is the active ingredient in...
TV Doctors Give Unreliable Recommendations
It’s always preferable to have objective empirical evidence to inform an opinion, rather than just subjective impressions. Confirmation bias will make it seem as if the facts support your opinion, even when they don’t. Of course, when objective evidence (such as published studies) does seem to support your position, you still have to keep your critical shields up. Confirmation bias can still...
Communicating Health Science News
A recent study addresses the problem of sensationalism in the communication of science news, an issue we deal with on a regular basis. The study was titled “The association between exaggeration in health related science news and academic press releases: retrospective observational study“. The results show two interesting things – that university press releases frequently overhype the results of studies, and that...
Risks of CAM Treatments for Cancer
“What’s the harm?” is an insidious idea when used as a justification for unscientific medical treatments. The argument is typically put forward with the assumption that direct physical harm is the only type of harm that can result from such treatments, so as long as they aren’t toxic there is no downside to trying them. Harm comes in many forms, however: delayed...
Low Dose Aspirin for Primary Prevention
A new study published in JAMA sheds further light on a controversial question – whether or not to prescribe low-dose aspirin (81-100mg) for the primary prevention of vascular disease (strokes and heart attacks). Primary prevention means preventing a negative medical outcome prior to the onset of disease, in this case preventing the first heart attack or stroke. Secondary prevention refers to treatments...

Chiropractors claim neck manipulation is safe. Evidence suggests otherwise.
