The Dark Triad Personality

Introduction

A few years ago I was diagnosed with generalized anxiety disorder and prescribed Fluoxetine (Prozac™) 20mg daily, a Serotonin reuptake inhibitor, which increases the quantity of serotonin in the synaptic gaps. The transformation was astounding. I saw the world completely differently than before and my interest in Psychology as part of my communication studies became an obsession.

So far I have hypothesized the following:

Logical fallacies and cognitive biases can reveal some personality traits, states, belief systems, subcultures and personality disorders.
Everyone perceives and reacts with the world through the filter of their hormones. ( I have seen the filters change within myself.)
We own our feelings. Our hormone balance, determined by our genetics / epigenetics, creates our general demeanor at homeostasis (default state) which can range from a positive outlook to a negative outlook, extravert, extrovert to patient, introvert, anxious, depressed, short-tempered or angry.
We often incorrectly attribute the cause of our feelings to external sources like relationships, and situations. This comes from our oldest instinct for survival, being always aware of potential danger.
Certain emotions governed by our hormones, are part of what is called the “preparatory set” which remain near the surface to be more likely triggered by stimuli. This is what makes each of us a unique personality.

Narcissism

Most personality traits are on a spectrum. Not all narcissists are willfully cruel, most don't realize what they are doing and nobody around them knows enough about the issue to correct them. I have a sibling, who always has the last word, loves to Zoom video conference and does nearly all of the talking, always knows more of what you are talking about and says "yes, that's right. and...(blah, blah, blah)", often but not always changes the subject to their own experiences. For the longest time I couldn't understand why when that person came to visit, it triggered subtle feelings of hostility in me. My temper was shortened because I was in emotional defense mode for competition I did not want. This kind of narcissism is mild but no less exhausting and exasperating. Narcissism standing alone can actually be beneficial, especially because this person is a teacher.

Psychopathy

Psychopaths as defined by the field of psychiatry is technically someone with Anti-Social Personality Disorder (ASPD). Psychopathy is a colloquialism and not a formal term used in the mental health field for official diagnoses.

Anti-social behavior can be summed up as follows:

Lack of emotional empathy but a clever sense of cognitive empathy.

Emotional empathy provides you with the ability to understand when doing something might hurt someone else's feelings and in-turn, hurt your own feelings. Along with cognitive empathy also provides you with a sense of what is fair and reasonable.

Uses malicious humor. (Passive Aggression)

Humor at the expense of someone else. Directing attention to your problems, for example, at Thanksgiving Dinner with extended family, or while at a restaurant dining in public with friends or strangers within earshot.

They try to goad you into revealing your weaknesses by making up fake weaknesses of their own.
They try to get you to reveal secrets you have about your friends by sharing gossip with you.
Then they use what you revealed to drive a wedge between you and whomever you spoke about.
They alter their persona around other people, even when you are there.

Machiavellianism

Based on the writings of Niccolo Machiavelli, called by some "The father of modern political philosophy and political science." Machiavellianism has come to be know as having these characteristics:

Manipulative
Callousness
Indifferent to social norms
Cold selfishness
Winning at any cost
Willing to do things other people find terrible or immoral
Low emotional self awareness or intelligence
