I am a constant follower of the Science-based medicine blogs.  They have several excellent writers including Mark Crislip who coined a widely quoted phrase about so-called integrative medicine, where science based medicine is mixed with all sorts of woo; acupuncture, homeopathy and the like. The phrase goes like this: ‘if you mix cow pie with apple pie, it does not make the cow pie taste better; it makes the apple pie worse’.

His latest post is great, discussing why otherwise rational doctors can be so seriously misled when it comes to evaluating the effects of ineffective therapies such as those mentioned above.
