Back from the grave
If human consciousness can really leave the body and operate without a brain then everything we know in neuroscience has to be questioned. If people could really gain paranormal knowledge then much of physics needs to be rewritten. This is what is at stake. Add to that the fact that most people in the population believe in some kind of life after death, and many desperately want it to be true, then you have a strong case for this research -- even if the chances of success are vanishingly small.
