&gt; I&#x27;m not comfortable in general about the idea of labeling people based on their neurological makeup, unless one is in a therapeutic&#x2F;psychiatric setting.<p>The setting you&#x27;re in has no bearing on whether people actually differ greatly based on their neurological makeup, though, so I don&#x27;t see how that matters.<p>We&#x27;re not on the same page here, but that&#x27;s to be expected, even if you&#x27;re actually not a psychopath yourself.<p>But what the world really needs to know is that because the difference between humans and psychopaths is so counter-intuitively vast, even seemingly small things are strong signs that someone is a psychopath.<p>For example, if someone keeps talking over you, he&#x27;s probably a psychopath. Because he has no respect for you as a human being, he&#x27;ll just casually interrupt you whenever he feels like saying something.<p>An actual human being wouldn&#x27;t do that, because he naturally respects you as another human being.
