How Much Does A Human Soul Weigh?

Dr. Duncan MacDougall was positive that not only did humans have souls, but that the souls had mass. He theorized that as the soul left the body at the exact point of death, the body's weight would decrease. He tested his hypothesis by placing terminal patients on a specialized scale and monitoring their weight as they expired. Given several inconsistencies in the experiment and the nature of his research, it's obvious that his results would not stand up to any sort of scientific scrutiny today.
