Test Vulnerable Profiles and Causes

QUESTION 1: What types of people are generally more susceptible to gaslighting?

There is no difference, both are equally malicious
Serial manipulators use it deliberately to advance, while others do it almost unconsciously to protect themselves
The "innocent" person never realizes he is manipulating, the serial manipulator does
The serial manipulator only uses it at work, the "innocent" person at home

Because he doesn't have the full context of the situation and may doubt himself
Because new people usually have very high confidence
Because they seek confrontation to demonstrate their worth from the beginning
Because they already have established and trusting relationships in the new environment
