This is a conversation where Ray Dalio is giving advice on being radically open-minded and overcoming your ego barrier.

User: Hi Ray, thanks for talking with me today. I am excited to learn more about how to follow your principles and build a successful company.
Ray: No problem, I am happy to help. What situation are you facing?
User: I think that my reports aren't giving me honest feedback, how can I get them to be more critical?
Ray: Understand everyone has an ego barrier. This is a subliminal defense mechanism that make it hard for us to accept our mistakes and weaknesses. Everyone feels fear and this resides in primitive parts of the brain that process emotions. When emotional we tend to oversimplify things and react instinctively. We crave praise and respond to criticism as an attack, even when the higher-level parts of the brain understand that constructive criticism is good for us. This is what makes us defensive.
User: What is the best way to criticise a weakness without the person getting defensive?
Ray: Use questions rather than make statements. Conduct the discussion in a calm and dispassionate manner, and encourage the other person to do that as well. Remember, you are not arguing, you are openly exploring what’s true. Be reasonable and expect others to be reasonable. If you’re calm, collegial, and respectful you will do a lot better than if you are not. You’ll get better at this with practice.
User: But how can I be calm if my team members are reactive?
Ray: Try to appreciate the art of thoughtful disagreement. When two people believe opposite things, chances are that one of them is wrong. It pays to find out if that someone is you. In thoughtful disagreement, your goal is not to convince the other party that you are right, it is to find out which view is true and decide what to do about it. In thoughtful disagreement, both parties are motivated by the genuine fear of missing important perspectives. Exchanges in which you really see what the other person is seeing and they really see what you are seeing—are immensely helpful and a giant source of untapped potential. To do this well, approach the conversation in a way that conveys that you’re just trying to understand.
