Dara O’Briain’s show on Science and the mind. Includes some fascinating ideas about what you can do with an MRI machine to see if people are telling the truth.
I once read “The Truth Machine” a novel about what society might be like if you applied lie detectors on a regular basis and how human interactions would change.
Anyway, it includes a discussion on the Psychopath test. See an example here.
Everything described is what we would call “black box testing” in computers – view it as a black box and probe it. Make assumptions about its behaviour based on its response to stimuli. I wonder if there is a piece missing, how many scientific theories that are based on observation would fall down if we actually figure out what was really going on.
