Pragmatic Studies – More Bait and Switch

The course of research into so-called alternative medicine (CAM) over the last 20 years has largely followed the same pattern. There was little research into many of the popular CAM modalities, but proponents supported them anyway. We don’t need science, they argued, because we have anecdotes, history, and intuition.

When media attention, which drove public attention, was increasingly paid to CAM then serious scientific research increased. A specific manifestation of this was the National Center for Complementary and Alternative Medicine (NCCAM). CAM proponents then argued that their modalities were legitimate because they were being studied (as if that’s enough). Just you wait until all the positive evidence comes rolling in showing how right we were all along.

But then the evidence started coming in negative. A review of the research funded by NCCAM, for example, found that 10 years and 2.5 billion dollars of research had found no proof for any CAM modality. They must be doing something wrong, Senator Harkin (the NCCAM’s major backer) complained. They engaged in a bit of the kettle defense – they argue that the evidence is positive (by cherry picking, usually preliminary evidence), but when it is pointed out to them that evidence is actually negative they argue that the studies were not done fairly. But then when they are allowed to have studies done their way, but still well-controlled, and they are still negative, they argue that “Western science cannot test my CAM modalities.”
