Ask HN: What are some winning strategies for the 'mind games' that people play?

Wikipedia defines 'mind game' as:

"1. a largely conscious struggle for psychological one-upmanship, often employing passive–aggressive behavior to specifically demoralize or dis-empower the thinking subject, making the aggressor look superior; also referred to as power games or head games.[1]

the unconscious games played by people engaged in ulterior transactions of which they are not fully aware, and which transactional analysis considers to form a central element of social life all over the world.[2]"

I value authenticity, sincerity, humility, and kindness above all else. Naturally, I am not good at playing mind games. However, I get dragged into them from time to time and want to know how to effectively deal with those kinds of people and situations without falling victim to them.
