Barry Ritholtz discusses how success in one area can lead to an unwarranted halo effect, making people believe individuals are expert forecasters in other, unrelated fields. He states that billionaires appearing on TV to make economic forecasts are often unqualified and that their success in business does not equate to predictive ability.
“They tend to do two things. Some are very similar to what other forecasters do, and some are very different. The thing they do that's similar is they talk their book, like everybody else does. Hey, I own these assets and I'm very enthusiastic about it. There's nothing wrong with that, the bias is there, you can't help it. But the things they do that are different is first, they're pretty unqualified to forecast, for goodness sake, most of the time they're not really qualified to do a deep dive into whatever they're talking about. But what makes this so dangerous is what we call the halo effect, which is when people see someone who's really successful in one specific sphere, hey, we apply a halo to everything they do and we imagine that that success is the same in everything else they touch. Spoiler alert, they're not all that successful elsewhere.”
