Mirroring - Wikipedia
Mirroring is the behavior in which one person unconsciously imitates the gesture, speech pattern, or attitude of another. Mirroring often occurs in social situations, particularly in the company of close friends or family. The concept often affects other individuals' notions about the individual that is exhibiting mirroring behaviors, which can lead to the individual building rapport with others.
It’s not a behavior that is only used by narcissists. It can often be an unconscious behavior that people end up imitating the people they spend the most time with. Mirroring is also a technique taught by NLP practitioners
, often to sales people and other people who are in the business of being persuasive. In the case of NLP it is a conscious decision to imitate the body language of the person you’re trying to build rapport with, and to consciously repeat words or phrases that your target uses back to them.
It is a technique that seems to come naturally to human predators such as sociopaths & NPDs, but they do it because it works.
