ELI5: What is the difference between a psychopath and a sociopath?
gpt
Those are no longer formal terms used in contemporary psychiatry and psychology. The appropriate term, according to the DSM IV (i.e version 4 of the Diagnostic and Statistical Manual of Mental Disorders) is _antisocial personality disorder (ASPD)_. 

What might have been called psychopathy and sociopathy in the past fall under the ASPD diagnosis. Medical professionals typically don't provide diagnoses of sociopathy or psychopathy; they would instead diagnosis ASPD. However the terms still get used quite frequently in the criminal justice system and in popular culture. 

In the past these terms were frequently used interchangeably, although sometimes a distinction was made based on the origin of the disorder Sociopathy was considered an acquired behavioral trait (potentially due to childhood trauma or abuse), while psychopathy was considered a biological trait. Under these conceptions, someone could be "made" into a sociopath by their environment but psychopaths were born that way.
