Note to our followers: Our nearly 13-year run of daily publication of new content on came to a close at the end of 2018. Publisher Gary Schwitzer and other contributors may post new articles periodically. But all of the 6,000+ articles we have published contain lessons to help you improve your critical thinking about health care interventions. And those will be still be alive on the site for a couple of years.

Our Comments Policy

COMMENTS buttonWe welcome comments, which users can leave at the end of any of our systematic story reviews or at the end of any of our blog posts.

But before leaving a comment, please review these notes about our policy.

You are responsible for any comments you leave on this site.

This site is primarily a forum for discussion about the quality (or lack thereof) in journalism or other media messages (advertising, marketing, public relations, medical journals, etc.)  It is not intended to be a forum for definitive discussions about medicine or science. 

We will delete comments that include personal attacks, unfounded allegations, unverified claims, product pitches, profanity or any from anyone who does not list a full name and a functioning email address.  We will also end any thread of repetitive comments.  We don”t give medical advice so we won”t respond to questions asking for it.

We don”t have sufficient staffing to contact each commenter who left such a message.  If you have a question about why your comment was edited or removed, you can email us at

There has been a recent burst of attention to troubles with many comments left on science and science news/communication websites.  Read “Online science comments:  trolls, trash and treasure.”

The authors of the Retraction Watch comments policy urge commenters:

“Shed light, not just heat. Facts, challenges, disagreements, corrections — those are all fine. Attacking the person, instead of the idea or the interpretation, is neither acceptable nor helpful.”

We”re also concerned about anonymous comments.  We ask that all commenters leave their full name and provide an actual email address in case we feel we need to contact them. We may delete any comment left by someone who does not leave their name and a legitimate email address.

And, as noted, product pitches of any sort – pushing treatments, tests, products, procedures, physicians, medical centers, books, websites – are likely to be deleted.  We don”t accept advertising on this site and are not going to give it away free.

The ability to leave comments expires after a certain period of time.  So you may find that you’re unable to leave a comment on an article that is more than a few months old.


Please note, comments are no longer published through this website. All previously made comments are still archived and available for viewing through select posts.
