> Because people who are good and social with the group do not have a contrarian character

That’s an interesting observation, and in my experience working in small businesses and large enterprise organizations, it’s entirely and totally wrong. Some of the worst people I’ve ever known in the workplace kiss up to the boss and to people in power while running the company into the ground. These are not good people. It’s actually a kind of evil in a way, as they present a likable "go along to get along" persona and facade while doing a terrible job. I would much rather be surrounded by humble yet candid truth tellers, who tell it like it is with empathy and compassion and care.
