Rapid Response:

Another bias for consideration:

Why do physicians and other health care workers see only what they
want to in randomised control trials?

I would like to add another bias to the excellent list suggested by
the authors; The 'rice bowl' bias.

To break someone's rice bowl is to take away his or her job. Is it
reasonable to expect those who make a living managing diabetic patients to
embrace an interpretation of a study that would have them break their own
rice bowls?
