Bridgewater rigged its "believability weighting" system to keep founder Ray Dalio on top, a new book says. That's according to "The Fund: Ray Dalio, Bridgewater Associates, and the Unraveling of a Wall Street Legend," out Tuesday from New York Times finance reporter Rob Copeland. Bridgewater's believability weighting system, in theory, was supposed to help determine how much weight a person's opinion carried and to help identify hidden talent within the firm. Bridgewater started experimenting with Dalio's believability weighting system with a prototype allowing staff to see each others' scores on a scale of 1-to-10, but Dalio wasn't pleased, the book said. In response to a request for comment from Insider on the book's assertions regarding the believability rating system, Bridgewater provided excerpts of letters that its lawyers sent to the book's publisher, St. Martin's Press.
