The article is a bit shallow, but since we're on the topic, I wanted to share a shower thought after seeing one of the videos of Punch.

Could a future society use videos like this one as a "lie detector" for sociopathic or psycopathic tendencies in people? I had very strong empathetic feelings when watching the video and I'm curious if the chemicals and neural pathways for such a feeling can be measured and detected reliably.
