Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
Believability-weighted decision making is a way of supplementing and challenging the decisions of Responsible Parties, not overruling them. As Bridgewater's system currently exists, everyone is allowed to give input, but their believability is weighted based on the evidence (their track records, test results, and other data). Responsible Parties can overrule believability- weighted voting but only at their peril. When a decision maker chooses to bet on his own opinion over the consensus of believable others, he is making a bold statement that will be proven right or wrong by the results.
