Robin Powell, who was given the name by Larry Swedroe in 2015 and is sometimes wrongly credited with coining it, sets out what it actually means: four tests of what counts as evidence, borrowed from a medical parallel that hit the same crisis twelve years ago. Including where he goes further than a global tracker, and why he holds that position less firmly than he used to.
