Hab mir den Wiki eintrag durchgelesen der wenig Info enthiel .
Nunja dann stieß ich auf den hier :

in dem folgendes steht :
But when you look more closely at his scientific work, you see large problems.
Firstly, six (as in the six dying patients) is not a large enough sample size. When I studied statistics, my lecturer convinced me that, concerning people preferring one cola to another, "
8 out of 10 is not statistically significant, but 16 out of 20 is".
Second, he got "good" results (ie, the patient irreversibly lost weight at the moment of death)
from just one of the six patients, not all six! Two of the results had to be excluded because of "technical difficulties". One patient's death did show a drop in weight of about three-eighths of an ounce - but this later reversed itself! Two of the other patients registered an immediate loss of weight at the moment of death, but then their weight dropped again a few minutes later. (Does this mean that they died twice!?) Only one of the six patients showed a sudden and non-reversible loss of weight of three-fourths of an ounce (21 grams).
The third problem is a little more subtle. Even today, with all of our sophisticated technology, it is still sometimes very difficult to determine the precise moment of death. And which death did he mean - cellular death, brain death, physical death, heart death, legal death, etc? How could Dr. Duncan MacDougall be so precise back in 1907? And anyhow, how accurate and precise were his scales back in 1907?
From such slender beginnings as a single non-reproducible result, enduring myths are born. There may be lightness after death - but this experiment didn't prove it. We do leave something behind us when we die - the enduring impact that we have had on others. We would probably have as much success in measuring the impression of that mental impact, as we would of measuring the weight of the soul.
