Researchers at the University of Kentucky and University of Central Florida who explored the neurobiology of the selfish-selfless spectrum found that most of us are neither extremely selfish (which results in becoming aggressive psychopaths) nor extremely selfless (which results in becoming zealous altruists).
Most of us are between these extremes, moving closer to one side or the other on the spectrum depending on the circumstances. When it comes to selfishness and selflessness, it turns out we’re not static, nor are we incapable of moving toward one end or the other. Breaking stories often prove out this fluidity, as they often include someone on the psychopath end of the spectrum who has done something extremely selfish; the answer to that are the altruists who step up and remind us there are amazing people ready to act, to call a halt to the actions of those who epitomize selfishness.
