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.
By identifying talents and preferences that lead people to feel a particular way, you can place them in jobs at which they will likely excel. At Bridgewater, we use a test called the "Team Dimensions Profile" (TDP) to connect people with their preferred role. The five types identified by the TDP are Creators, Refiners, Advancers, Executors, and Flexors.
Triangulating what I learn from each test reinforces or raises questions about the pictures of people I'm forming in my head. For example, when people's MBTI results suggest a preference for "S" (focus on details) and "J" (planful), and they come out as executors on the Team Dimension assessment, there is a very good chance that they are more detail-focused than right-brained and imaginative, which means that they would likely fit better in jobs that have less ambiguity and more structure and clarity.
