The brains of psychopaths have a key difference compared to other people when presented with these two situations.
If you’re curious about how people tick or enjoy studying any of the behavioral or brain sciences, you’ll want to see this. This is wicked.
Dr. Kevin Dutton of BigThink describes two situations of life and death that involve a trolley. If a doctor were scanning your brain and a psychopath’s brain while you listened to Dutton explain, a key marker would be missing in the psychopath’s brain.
Watch the video on BigThink to hear Dutton explain in this four minute video.

I do find the advances – so fast – that are being made in neuropsychology and understanding of human behaviour quite amazing. They just keep on outstripping our capacity to use lanaguage.

The issues of Sociopathic – Psychopathic conduct have come up here quite a few times, but mainly around the issues of Trolls – Or as I prefer “Netopaths”. We can either be slaves to language or use it as a tool for communication. I keep collecting tools as a sort of word geek. Psycopath and Sociopath are to all intents and purposes interchangeable, and in the DSM debates one or even both are to vanish to be replaced with yet more verbage. The DSM 5 Antisocial Personality/Psychopath labelling system may… Read more »
