For a change of pace, I want to step back from medicine for this post, although, as you will see (I hope), the study I’m going to discuss has a great deal of relevance to the topics covered regularly on this blog. One of the most frustrating aspects of being a skeptic and championing science-based medicine is just how unyielding belief in pseudscience is.
