President Trump just fired the head of the Bureau of Labor Statistics, accusing her of cooking the books for political purposes. Her replacement, economist E.J. Antoni, is already rattling cages by suggesting we should scrap the BLS’s jobs report altogether. The firing wasn’t exactly tactful from a PR perspective, but the new guy is actually onto something. Unburdened by market pressures, subpar government stats distort the minds of policymakers, encouraging radical action when we don’t actually know what’s going on. Another Trump official, Dr. Vinay Prasad, has blown the whistle on this exact problem in his area of expertise—cancer screening. The analogy is stronger than you might think, and “Do No Harm” isn’t just a good mantra for medicine.
