Out of curiosity I browsed Wikipedia which had this to say:
Psychopathy emphasize three observable characteristics to varying degrees:
- Boldness. Low fear, high tolerance of stress, unfamiliarity and danger, and
high self-confidence and social assertiveness.
- Disinhibition. Poor impulse control including problems with planning and
foresight, lacking affect and urge control, and demand
for immediate gratification. Low conscientiousness.
- Meanness. Lacking empathy and close attachments with others, use of cruelty
to gain empowerment, exploitative tendencies, defiance
of authority, and destructive excitement seeking.
https://en.wikipedia.org/wiki/Psychopathy#DefinitionI am surprised that the tendency to compulsively lie is not also in the Wikipedia definition.
If you already don't like this coworker because of disagreements and actions at work, you're very likely to overestimate these symptoms, or believe that someone who is only a little ways along the spectrum to psychopath is actually much further.
Imagine if we believed everyone who went through a bad breakup or divorce and called their ex partner a psychopath out of anger (even justified anger). It just seems really extreme to use some armchair diagnosis from someone emotionally invested in believing bad things about the other person.
Again this post was a message to any founder finding a partner. Things may be rosy in the beginning but if you are paired with someone who fundamentally is only motivated by money they will always choose their own interest over the company. Even if that means actively sabotaging and slandering.
Again I do not want to air dirty laundry but I was landed the unfortunate worst case scenario.
Anyone who thinks that I am being one sided is allowed to have that prerogative. I cannot give full details but please imagine the worse situation you can get into with a first partner, I am talking them trying to smear your reputation and sabotaging the company in order to get their way, not just some friendship that went bad. Please proceed with caution and do not be overly trustworthy.
If anyone wants to know more I would be happy to talk directly. But I'm sharing this because founders with genuine intentions and the ones who get damaged the most by individuals like this.
Your problem seems, based on what you say, a lot more narcissistic than the guys I had to deal with - yes, that is actually a positive, believe me. The problem is obvious... I lost 5 years of my life to this stupid startup and got little out of it except some harsh life lessons.
Good luck, and if you don't have a lawyer, get one.
I have never really met "crazy" or understood in a direct sense what "psychopathic" meant but to associate certain word I would attribute the following as to what I mean as psychopathic with this individual: "a pathological liar", "self-destructive", "narcissistic", "irrational", "vitrolic". I mean this person thought he was the next coming of Marc Andreessen.
In an objective sense it is unfortunate that there are actually people who live like this. But I wrote this article to warn start-up founders that are just starting out looking for a co-founder or a "mentor". I was just a PhD engineering student when I started, I did not know how to adequately gauge business prowess or to read through a person like this.
I can say I've learned what NOT to do and what NOT to be like. Now I am a less trusting and more guarded person.
