One of the highest indicators of intelligence is one's ability and willingness to change their mind.
Extremism frighten me. I’m not referring to terrorists, I’m talking about people who live in the world of absolutes. In black and whites. Whether it has to do with religion, social issues, technology, or politics, anyone who refuses to change their mind despite compelling evidence or opinion annoys me. People who relentless try to convert me to their position truly scare me. I think such behavior is the opposite of intelligence; it’s mindless.
Don’t refuse to change your mind because you fear it will invalidate your past actions, beliefs or recommendations. From my perspective, I will respect a person far more if they’re able to recognize a potentially wrong path, correct their trajectory, and know why they did it.
