Narcicistic men usually stand out like a sore thumb.

They instincivtely care a great deal about their physical appearance, and often dress with a style that is flashy; they stand out, in the visiual sense.

Also, their extroversion and their desire for attention, makes them stand out.

Psychopathic men are usually masters of blending in; they are very good at concealing their psychopathy.

Most people who know them would report that they are ‘normal’ and 'likeable'; nothing particularly unusual about them.

Autistic men stand out.

When you interact with an autist, it’s obvious within the first 60 seconds of interaction that their personality isn’t normal; they are clearly an outlier. Hopelessly socially awkward. Not cunning at all.

Autistic men are easy to detect.

Narcissistic men are easy to detect, but not as much as autistic men.

Psychopathic men are hard to detect; you usually don't notice them until you feel a knife in your back.

Narcissists tend to not be very intellectually curious.

Narcissists care intensely about worldly wealth; money, power, status.

They care intensely about being good looking; physically attractive.

However, they tend to find things like philosophy boring.

You will never meet a narcissistic man who thinks that the works of Nietzsche and Socrates are interesting.

Autistic men seem to be the opposite, in this regard.

Most autistic men are far less interested in worldly wealth than the average person; they claim not to desire wealth, power, or status.

They claim that they are interested in technological innovation and scientific advancement.

It would seem that they are telling the truth.

A narcissistic billionaire like Donald Trump is interested in maximizing his own power; to such a man, there is no higher goal than to become President of the United States, reaching the pinnacle of the macro dominance hierarchy.

An autistic billionaire like Elon Musk isn’t primarily motivated by enhancing his own power.

His primary motivation is to ‘change the world’ through technological innovation; self driving cars, solar power, space travel.

It seems that autism, is a vaccine against narcissism.

You will never encounter an autistic person who is narcissistic; autism and narcissism seem to be mutually exclusive psychological conditions.

Narcissism and psychopathy are not mutually exlusive; many men are both psychopathic and narcissistic.

Ted Bundy and Jordan Belfort are men who are both narcissistic and psychopathic.

Vladimir Putin is a man who is psychopathic, but not narcissistic.

Narcisstic men are a paradox in the following sense; they are volatile, yet also predictable.

They can go from enthusiastic to angry, and back again, very quickly.

Yet at the same time, predicting their behavior is simple;...

simply ask "What would the stereotypical highschool bully do?"
