The Misinformation Wars

The core mission of SBM comes down to a few things – examining the complex relationship between scientific evidence and healthcare, exploring issues of how optimally to regulate health care and health products, and fighting misinformation. Over the years I think we have made some solid strides on the first category. The medical infrastructure has been trending increasing towards higher standards of...

Will AI Save Medicine

Modern medicine is facing many challenges. As the science of medicine advances, it gets harder and harder. We have, in a way, picked all the low hanging fruit. People are living longer, and their medical conditions are getting more challenging to understand and to treat. In order to continue making medical progress we need more advanced technology. This technology – like stem...

A man in a suit, identified as Mr. Kennedy, gestures while speaking at a microphone during a formal meeting or hearing. He has gray hair and is sitting at a table with name placard, papers, a coffee cup, and water bottles. People are visible in the background.

David Geier Hired to Study Vaccines and Autism

If you are already tired of hearing about RFK Jr. being the Secretary of Health and Human Services (HHS), buckle in. I get it – it can be exhausting. Don’t we already know everything we need to about what a medical crank he is? While SBM will not neglect the many topics that we cover, we certainly consider it a high priority...

A woman in a red outfit speaks into a microphone with the text "DON'T EAT IT." A large text above reads "No More Peanut Butter ✘." The video appears on a TikTok interface with engagement icons on the right side.

On TikTok, Everything Is a Poison or Superfood

We have to face the fact that social media is now the primary way that many people get their information. More than half of people in the US get their “news” from social media at least some of the time. But I don’t think asking people where they get “news” captures the full phenomenon. People who watch TikTok videos might not consider...

World map showing measles cases by country in 2018. Dark red indicates the highest number of cases (over 45,000), while light beige indicates the lowest (under 400). Notable high-case regions include Madagascar and Ukraine.

Vitamin A Does Not Treat or Prevent Measles

It didn’t take long for concerns about RFKs unscientific ideological approach to healthcare to manifest. We are in the middle of a measles outbreak – the exact kind of situation for which we need a strong federal response. The person in charge of that response, RFK Jr., is a notorious anti-vaccine crank who is not a scientist or healthcare expert, even though...

Looking Back 5 Year Later – Were Lockdowns Worth It?

An excellent article on the BBC gives a good overview of the continuing controversy over universal lockdowns as a pandemic mitigation strategy during COVID. We now have significant data about how various countries around the world fared compared to their mitigation strategy. Interestingly, this data is unlikely to resolve the controversy. But it can inform our decisions for the next pandemic –...

A child with brown hair sits cross-legged by a cozy window, reading a book. Snow falls outside. The room is warmly lit, with books, a teddy bear, and glowing string lights. A steaming mug rests nearby, creating a serene and inviting atmosphere.

Redefining Dyslexia

What, exactly, is dyslexia? What causes it, how should it be diagnosed, and stemming from that, how should it be treated? We can even ask a more fundamental question – does it actually exist as a discrete clinical entity? These questions have existed since dyslexia was first described and named in 1887, by German Opthalmologist, Rudolf Berlin. Not surprisingly, he thought the...

A woman with brown hair tied back wears large, dark sunglasses and a dark coat. She is walking outside, with a blurred urban background. Another person is partially visible beside her.

Apple Cider Vinegar

I just watched the new Netflix series, Apple Cider Vinegar, which tells the story of Belle Gibson, an Australian woman who launched a wellness business based largely on the false claim that she had survived “terminal brain cancer”. It is worth a watch, and overall I feel the writers (this is a fictionalized version, not a documentary) captured the industry of fake...

BBC Takes On Appeal to Nature Fallacy

It’s always good (and frustratingly rare) to see the mainstream media get it right when it comes to pseudoscience in medicine. Too often the narrative is – scientists are baffled at this alternative “one easy trick” to improve your health. Most mainstream articles on pseudoscience in medicine frame their reporting around a positive anecdote, and at best throw in some token skepticism...

Three people are in a room. One is seated, holding a pen and an object. Another sits nearby, partially visible. A standing woman holds a card with "2" on it. Text on the image reads "(C) THE TELEPATHY TAPES.

The Telepathy Tapes – More FC Pseudoscience

Documentaries can be powerful. They can use the mature art-form of cinema in order to convey a specific narrative. The viewer can get drawn into that narrative, unaware they are being exposed to a very one-sided or limited take on a complex topic. I recently, for example, participated in a fun review of the Earthing Movie which was basically propaganda for the...
