If you have spent any time here this headline isn’t new.   Not too bad as mainstream articles go.  Turns out psychopaths can imagine pain from a physical injury fine for themselves, just not for others.

Hare’s psychopathy test get’s a hat tip too.

Nice for a study to reenforce the conscience as the sole missing piece.   Even if the article wasn’t explicit in that.
