The key criteria for something to be called a psychological disorder is it has to hurt the patient in some way, causing them a disadvantage in life. To flesh this out: >Studies have shown that women are attracted to these personality traits in men. Woman are attracted to men who are as successful or are more successful as them. NPDs and ASPDs (though more rare than NPDs) can fake being successful and others fall for it. This relationship is often short lived once they realize they were tricked. The most common form of employment for someone who is ASPD (what you're calling psychopathy) is being a homeless alcoholic. The second most common is being in prison. The leading theory is ASPD is an adult who did not grow out of their terrible twos. This does not help an individual succeed in any shape or form. ASPDs do not and can not maintain relationships for a long period of time, and the few high functioning ones not in prison or homeless roam around like nomads from town to town leaving once they are no longer welcome. Machiavellianism is a philosophy or a set of beliefs. It is not a psychological disorder. It does not harm the belief holder. Machiavellianism is a sort of game theory on a macro nationwide scale. I can continue with NPD (narcissistic personality disorder), but I can assure you in the long run it does not benefit them. They believe manipulating people is better for them and will jump through mental hoops to justify their behavior to themselves. When someone is thought of as a con artist or a gold digger, that is most likely someone who is NPD. >On a group level, anxiety in individuals may be evolutionarily advantageous Anxiety is assuming (usually unconsciously) a negative outcome will happen. It's a danger feeling. When anxiety moves from a rare feeling to a disorder, it's because they're overly assuming/believing faulty futures. This can come from faulty logic, or being told incorrect beliefs during childhood, or many other situations. Anxiety as a disorder has no advantage to the user.
