Social comparison orientation is significantly correlated with psychopathy, Rob Henderson explains:
In other words, people who habitually compare themselves with others are more likely to have psychopathic traits (selfishness, callousness, cynicism).
And psychopathy, in turn, was associated with more comfort with sacrificing a few to save many.
Social comparison is also associated with narcissism. People prone to comparing themselves with others agree more strongly with statements such as “I am great” and “Other people are worth nothing.”
[…]
Later, I learned that psychopaths are overrepresented among college students by a factor of four. Roughly two percent of the general population are psychopaths, compared with 8 percent of college students.
[…]
Other studies find that people who frequently compare themselves with others are more likely to experience malicious envy.
They tend to agree with statements like “If other people have something that I want for myself, I wish to take it away from them” and “Seeing other people’s achievements makes me resent them.”
[…]
Social comparers prefer to make everyone else worse off, if it means they will obtain a relative advantage.
Also unsurprisingly, social comparison was highly correlated with competitiveness (“I judge my performance on whether I do better than others rather than on just getting a good result”).
