Ultimately I think all of what you describe there falls into a bucket of personality traits and social skills that contribute to success in many areas of life.

It's some combination of what they call "self monitoring" in social psychology, plus general EQ and Machiavellian personality traits that allow people to read the room and adjust their tone, speaking style, word choice (including picking up in-group lingo quickly), posture etc to be most effective given the setting. This applies to basically any social environment, and is often a frustrating reality to many people who may be extremely competent but see others around them who are obviously less competent "getting ahead" through social acumen, office politics etc.

This has been studied among MBA graduates, Do Chameleons Get Ahead, The Effects of Self-Monitoring on Managerial Careers (pdf): https://web.mit.edu/curhan/www/docs/Articles/15341_Readings/...
