Here is sone ways to tell if you are NOT.
1)You don't know if You are
2) it worries you of you are
3) You would want to be one
4) you claim to be one
6) you gloat and act professional about being one (May even start a website about being one)
I disagree completely.
We are born into this world with a blank slate. Our mind learns words by relating them to things. If we don't have something to relate to sociopath, how can one know? How can any individual know they are any different from the rest of Humanity?
It's not so simple I think.
