21 grams experiment
The scientific community has rejected MacDougall’s experiment. He has been accused of using bad methods and even cheating to get his results. Karl Kruszelnicki said that this is a case of selective reporting, This is because only one of the six patients measured supported the hypothesis. MacDougall also ignored most of the results. Kruszelnicki also said that the sample size was too small. He asked how MacDougall could know the exact moment when a person died with the technology at that time. Physicist Robert L. Park said that MacDougall’s experiments are not considered good science “today”. Psychologist Bruce Hood said that the weight loss was not reliable or repeated, so MacDougall’s findings were not scientific. Professor Richard Wiseman said that scientists think the experiment is “almost certainly not true”.
