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.
A poll asked Britons to choose between £50,000 for certain or a coin flip for £1 million. Nearly three quarters took the sure thing. Expected value says they were wrong. Rationality says they might be right. The real insight lies in what the choice reveals about risk — and how to make the right decisions when it matters most.
