Nobody can establish who first used the phrase 'evidence-based investing', and no regulator defines it. 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.
Investors are turning to AI hoping it will cut through the emotional noise and deliver clearer, more rational financial decisions. But two recent studies suggest these tools don't neutralise investor biases — they absorb them. And the more advanced the model, the worse the problem may get.
