So, I just found out that not all those who lack empathy are sociopaths. It turns out that there is a whole personality set aside all by itself that generally lacks empathy. I find this to be hilarious.
And disturbing. Not because I think this personality type is dangerous, but because I think the oversimplification of the common understanding of sociopathy is dangerous. Stereotypes have their place and are useful in navigating our complex social world, but oversimplifications of highly defined behavior sets can lead to a whole group of people being marginalized, or even ostracized, because of their base personality.
This personality type is good and useful. It is rare, coming in at a mere 2% of the world's population. It is known to its personality system as the Architect, and people of this personality base are extremely intellectual, cunning, precise, curious, energetic and efficient. And they get the best grades in school.
We know that people love this personality type because it makes up an estimated 13% of personality types in fictional literature. Of course, pegging the personality of fictional persons is difficult so take this number with a grain of salt, but also note that the most common personality in this particular personality system is approximately 14% of the global population. Even if the numbers are a little off, it is pretty clear that most people enjoy books with this personality as the lead.
So, please be careful and do your research. Diagnosing someone as a sociopath when all they have is rare personality type could cost you a friend, and could destroy what few chances they have at normal relationships. God created this personality type and has called it "good." Please don't call it evil.
