MacDougall's experiment has been the subject of considerable skepticism, and he has been accused of both flawed methods and outright fraud in obtaining his results.[9] Noting that only one of the six patients measured supported the hypothesis, Karl Kruszelnicki has stated the experiment is a case of selective reporting, as MacDougall ignored the majority of the results. Kruszelnicki also criticized the small sample size, and questioned how MacDougall was able to determine the exact moment when a person had died considering the technology available at the time.[2] Physicist Robert L. Park has written that MacDougall's experiments "are not regarded today as having any scientific merit",[5] and psychologist Bruce Hood wrote that "because the weight loss was not reliable or replicable, his findings were unscientific".[9] Professor Richard Wiseman said that within the scientific community, the experiment is confined to a "large pile of scientific curiosities labelled 'almost certainly not true'".[4]
