Why are experts' beliefs and predictions so often wrong in their own areas of expertise? In Wrong but Useful: Why Experts Have Blind Spots, Yale Professor of Finance James Choi will argue that experts are led astray by being only partially adherent to statistician George Box's famous saying, "All models are wrong, but some are useful." He will draw, among other things, on his recent experience of having his paper, "Popular Personal Financial Advice versus the Professors," go viral.
