Robert Aronowitz wrote an interesting historical analysis on the background of the current mammogram debate titled: Addicted to Mammograms.  His analysis provides another layer of meaning to the debate, which is my point.  Evidence must be interpreted. Aronowitz infers that the people at the Preventive Services Task Force, who made recommendations based on their interpretation of the evidence, didn’t understand how it would be re-interpreted in the media and the health industry, especially in the context of the current health insurance reform debate. But evidence and interpretation are two sides of the same coin.  One side may be stamped with permanent maker and the other with erasable marker, but you can’t have a one sided coin.  . . . Well, . . . maybe physicists can have a one sided coin, but not the rest of us mortals.
