Sarah Hershberger: “Health freedom” and parental rights vs. child welfare
One of the more depressing topics that I regularly write about on this blog includes of analyses of news stories of children with cancer whose parents decided to stop science-based treatment (usually the chemotherapy) and use quackery instead. There are, of course, variations on this theme, but these stories take form that generally resembles this outline: A child is diagnosed with a...
Presidential candidate Ben Carson: Shilling for Mannatech with his very own alternative cancer cure testimonial?
Over the years, mainly at my not-so-super-secret other blog, I’ve frequently made the points that the vast majority of physicians are not scientists and, in fact, that many of them suffer from a severe case of Dunning-Kruger when it comes to science outside of biomedical sciences—or even biomedical sciences outside of their medical field of expertise. The most common science I’ve seen...
Antivaccine activists fund a study to show vaccines cause autism. It backfires spectacularly.
Having written about pseudoscience and quackery continuously for over a decade and having engaged in conversations about it online for over 15 years, I’ve come to recognize a number of traits that are virtually the sine qua non of quacks and pseudoscientists and their believers. Obviously, one of them is a severe case of the Dunning-Kruger effect, a tendency of those with...
“Liquid biopsies” for cancer screening: Life-saving tests, or overdiagnosis and overtreatment taken to a new level?
I’ve written many times about how the relationship between the early detection of cancer and decreased mortality from cancer is not nearly as straightforward as the average person—even the average doctor—thinks, the first time being in the very first year of this blog’s existence. Since then, the complexities and overpromising of various screening modalities designed to detect disease at an early, asymptomatic...
Donald Trump and the dangerous vaccine politics of the 2016 Presidential race
At the second Republican debate of the 2016 election cycle, Donald Trump parroted antivaccine pseudoscience, and Ben Carson walked back his previously strong support for vaccine mandates. Earlier in the campaign, Rand Paul blamed vaccines for "neurologic injury," and Chris Christie briefly pandered by questioning vaccine mandates. What's going on here? Is the Republican Party becoming the antivaccine party?
The Federal Trade Commission takes on homeopathy—maybe
Well, I’m back. OK, returning from London isn’t nearly as epic as Sam Gamgee’s final words in The Lord of the Rings returning to his wife and daughter after having accompanied Frodo, Gandalf, Bilbo, and key elves of Middle-Earth to the Grey Havens, there to say goodbye to them as they boarded a ship to the undying lands. I just love the...
How should we treat DCIS?
I’ve written more times than I can remember about the phenomenon of overdiagnosis and the phenomenon that is linked at the hip with it, overtreatment. Overdiagnosis is a problem that arises when large populations of asymptomatic, apparently healthy people are screened for a disease or a condition, the idea being that catching the disease at an earlier stage in its progression will...
“Aborted fetal tissue” and vaccines: Combining pseudoscience and religion to demonize vaccines
As hard as it is to believe after seven and a half years of existence and nearly 2,400 posts on SBM, every so often, something reminds me that we here at SBM haven’t discussed a topic that should be discussed. So it was a couple of weeks ago, when I saw a familiar name in a news story that wasn’t about vaccines....
