Low-IQ sociopaths are usually violent or antisocial to the point they regularly commit crime and get caught. A non-insignificant percentage of prison population is sociopathic.

Mid-tier sociopaths have learned to socialize and blend in, but still have tells that belie low empathy, like a lack of remorse, inability to recognize social boundaries, or a lack of concern if they've been caught in a lie. Some of them are thrill-seeking, so find outlets for anti-social tendencies, such as racking up speeding tickets, a reckless fascination with weapons, or some sort of vice on the down-low (gambling, drugs, etc...). These are the ones that tend to burn out in middle age.

High-IQ, high-functioning sociopaths are highly likeable and usually end up leading people in some capacity. If you find yourself constantly making excuses for a politician or CEO, reconsider their pathology.
