“But science should be based in fact, not fashion. And policy should be based on science. Facts shouldn’t change. And indeed, they don’t. But their interpretation does. Consider the idea that inflammation causes heart disease. First espoused in the late 1800s after the invention of aspirin by Bayer, this idea was relegated to the dustbin of medical science in favor of the cholesterol hypothesis, which reigned for the second half of the twentieth century. But over the last decade, the “inflammation hypothesis” has made a decided comeback, and is now thought to be the primary factor in the genesis of atherosclerotic plaques and thrombosis.”
