It really surprises me, sometimes, how willing some people are, to believe in something simply because they have never heard of it before, and conclude that no one else must have heard of it either. Has anyone noticed that many of the theories seen on this forum, such as the various "proofs" of creationism, of psychic powers, of ghosts, of all those phenomena that have existed for millenia, are the exact same theories that have been heard and repeated over and over again by every new generation that comes by? For a real phenomena to have such little in the way of variation is astounding. Where are the new accounts? Where are the modern studies?
I would submit that the simply reason these things are still in the general conscious is only because the new generation is so excited at discovering something so beyond mainstream that it dispenses with the simple step of confirmation in the eagerness to proclaim that they have knowledge beyond that that the authority figures over them have. The sole reason these stories continue to exist is simply so that the young can stroke their newly emerging egos concerning their individuality. By holding these alternative theories as trophies, they proudly seperate themselves from a conventional maturity they both envy, yet are too "cool" to express a desire to be a part of.
But I digress. We are talking about the weight of a soul. 21 Grams.
Has anyone bothered to check the credibility? The source?
Almost a full century ago, back in 1907, Dr. Duncan MacDougall of Haverhill, Massachusetts theorized that the soul was material, and therefore, should be able to be measured at the precise time of death, by comparing the weight of a person still alive to that of a person deceased. His test sample consisted of 6, only six, people. The test bed was, quite literally, a bed, a cot actually, no metal or plastic or anything, set atop a set of scales accurate to 2/10ths of an ounce. For those that would object to such a lack of precision measurement, remember that this was still the turn of the century technology, and the man did the best he could.
So, what were the results? Out of six tests, two had to be discarded, one showed an immediate drop in weight, two showed an immediate drop in weight which increased with the passage of time, and one showed an immediate drop in weight which reversed itself but later recurred. To be perfectly frank, the results were haphazard, to say the least. Several problems plagued the study, not the least of which was determining when, exactly, the subject was dead.
He also tried to repeat his experiments on fifteen dogs. I could go into the various problems such a study has, including a ridiculously small representative sample, an inability to remove various factors which could have compromised the experiment, and certain interpretations of results that were...questionable. To be fair, Dr. MacDougall was conducting what he considered a serious scientific study, but he simply didn't do it very well, partly because the technology of the 1900's just wasn't there, partly because scientific methodology in those days wasn't what we consider acceptable today, and partly because...well, he just didn't do a very good job.
Nonetheless, on thing stands perfectly clear. For those arguing against this, there is absolutely no reason to go theorizing on what could have caused a sudden loss of weight in a dead body until such time that it is confirmed that a sudden loss of weight actually occured. For those arguing in favor of this, please consider: You are basing your arguments on a single experiment done once over a century ago, and not even done properly at that. To be frank, the majority of what this thread has contained, such as precision scales, metal beds, IV, and whatnot, all that has been added by rumor and time. This study has become nothing more than an urban legend, and should be accorded only that amount of credibility one gives to such outlandishly exagerated stories.
I invite you to read about the original studies.
