 A relative lack of socio-political power is almost certainly one source of vulnerability to manipulation. But there are likely others as well. The trickery model of manipulation suggests that people who are less intellectually sophisticated are especially vulnerable to trickery and therefore to manipulation. The pressure model suggests that financial, social, and emotional desperation may make one especially vulnerable to pressures created by threats to worsen an already tenuous situation. Moreover, some forms of manipulation, like so-called “negging” (tactic 6) and gaslighting  (tactic 8)  may work to increase the target’s vulnerability to further manipulation.
