Narcissism is typically associated with more extroverted types.
I have actually done quite a bit of reading about personality disorders. I had a relationship with someone who had significant cluster B tendencies (Narcissistic/Histrionic/Borderline) he is an ESFJ. It was crazy-making and confusing...I knew that something was horribly wrong. It was actually all of the personality research that lead me to you guys
Based on Morgan's comment, I wanted to point out there is something called "inverted narcissist". Inverted (or covert) narcissist are the perpetual "victim". And as with overt narcissist, the world revolves around them, just in a backwards kind of way. Narcissist often end up in (highly-dysfunctional) relationships with Inverted Narcissist, BTW. Because it makes the perfect victim/perpetrator relationship.
Below are the symptoms of covert narcissism, beneath each one is the inverted (covert) equivalent:
Feels grandiose and self-important (e.g., exaggerates accomplishments, talents, skills, contacts, and personality traits to the point of lying, demands to be recognized as superior without commensurate achievements);
Feels victimized by everyone often without cause or justification.
Is obsessed with fantasies of unlimited success, fame, fearsome power or omnipotence, unequaled brilliance (the cerebral narcissist), bodily beauty or sexual performance (the somatic narcissist), or ideal, everlasting, all-conquering love or passion;
Feels damaged, worthless and inferior compared to others and constantly seeks to measure up. May be obsessed with comparing themselves to others and overly focused on others' perceptions and opinions.
Firmly convinced that they are unique and, being special, can only be understood by, should only be treated by, or associate with, other special or unique, or high-status people (or institutions);
Feels misunderstood, unique, and victimized. Will often isolate themselves from people.
Requires excessive admiration, adulation, attention and affirmation — or, failing that, wishes to be feared and to be notorious (narcissistic supply);
Requires excessive sympathy and attention
Feels entitled. Demands automatic and full compliance with their unreasonable expectations for special and favorable priority treatment.
Is "interpersonally exploitative", i.e., uses others to achieve their own ends;
Demands sympathy from others and requires immediate attention for imagined crises. Will punish people off for not meeting their demands for constant attention and immediate availability.
Devoid of empathy. Is unable or unwilling to identify with, acknowledge, or accept the feelings, needs, preferences, priorities, and choices of others;
Same
Constantly envious of others and seeks to hurt or destroy the objects of their frustration. Suffers from persecutory (paranoid) delusions stemming from a belief that others are envious of them and are likely to act similarly;
Constantly envious of others and seeks to hurt or destroy the objects of their frustration. Suffers from persecutory (paranoid) delusions stemming from a belief that others are victimizing or judging of them.
Behaves arrogantly and haughtily. Feels superior, omnipotent, omniscient, invincible, immune, "above the law", and omnipresent (magical thinking). Rages when frustrated, contradicted, or confronted by people they consider inferior to themselves and unworthy.
Behaves as a perpetual victim. Feels inferior, misunderstood, unique and imagines malicious intent from others where there is none. Rages when frustrated, contradicted, or confronted by people they feel victimized by.
I think these qualities are much more likely to appear in Introverts...but that is just conjecture on my part
I hear these online tests are 100% accurate, BTW.
