What’s dead to you?
The researchers Kurt Gray of the University of Maryland’s Mind Perception and Morality Lab, together with Annie Knickman and Dan Wegner of Harvard University would like to know. They’ve recently designed an experiment to try and uncover how we perceive those in persistent vegetative states, or PVS. And what they’ve found so far is astonishing, even perhaps a complete uprooting of zombie studies.
The researchers stopped 201 random subjects in public spaces throughout New York and New England. Participants read one of three random, hypothetical short stories. In all three, a man, David, smashes up his car and suffers “serious injuries.” Fates vary – in one, David fully recovers; in another, David dies; and in the third, David’s entire brain goes dark, save the one chunk that keeps him breathing. He’s alive, by legal standards, but won’t ever really come to. David’s a vegetable.
Subjects were then asked to size up his mental abilities. Could David “influence the outcome of events, know right from wrong, remember incidents from his life, be aware of his environment, possess a personality” or otherwise be emotional? They rated his capacities on a seven-point scale:
3 – David can do these things.
0 – You don’t agree or disagree that he can do these things.
-3 – You “strongly disagree” that he can do these things.
