know thyself

What is the psychology underlying people who imitate others a lot?

Such people tends to fall into either one of three categories. First, they might be suffering from low self-esteem and therefore do not believe their own thoughts, feelings, and behaviors are good enough. Second, they want to fit in with a certain “type” of person, and that won’t be possible if that person is not accepting of him/her having their own thoughts. Third, the imitator might simply be overwhelmed by someone’s “charisma,” either negative or positive, and rather than go against the tide of that charisma, it’s easier to just succumb to it.

They might not even recognize it as copying rather they usually do it kind of innately.
