Can you cite a source? I'm under the impression that both of these terms are considered outdated, in that modern psychology doesn't really think "sociopathy" or "psychopathy" are good abstractions.

I'm under the impression that "sociopathy" is kind of used synonymously with antisocial personality disorder but has fallen out of favour because of the pop psychology baggage it carries, and "psychopathy" is mostly used in media/criminal justice tropes.
