There is a 21+ minute video at the top of the article that starts shortly after the article is opened.
The actual sanity test I found is called, by delicious coincidence, “The Hare Psychopathy Checklist.” Introduced by Canadian criminal psychologist Robert D. Hare in 1980, it is still in use, though with ever more diffuse and specific mental-health diagnoses, it is not without its critics. However, as a practicing therapist who walked me through it agreed, it serves as a kind of triage device to separate the injured from the tripping from the psychopathic.
And about that word. We seem to have completely muddied up sociopath and psychopath. Sociopath? Roughly speaking, think Ted Kaczynski, the Unabomber, living out there in his shack in the woods, feeling nothing for other humans and unable to interact with them, literally mailing it in. Psychopath? Think Ted Bundy, feeling nothing for other humans but having long ago learned how to expertly mimic relationships by being whatever he needed to be to whomever he needed to use, killing at least 30 women, serving as his own counsel and cross-examining a female witness, proposing marriage to her while she was on the stand—and getting her to say “yes.”
For each of the 20 items on the Hare Psychopathy Checklist, you’re supposed to assign the subject a 0, 1, or 2. The highest and most dangerous score is a 40. In the U.S., the accepted minimum score for possible psychopathy is 30.
