About four years ago I wrote a post about the AWARE (AWAreness during REsuscitation) project being lead by Dr. Sam Parnia. The AWARE project is summarised on its official website as being about “using the latest technologies to study the brain and consciousness during cardiac arrest… [and] testing the validity of out of body experiences and claims of being able to see and hear during cardiac arrest through the use of randomly generated hidden images that are not visible unless viewed from specific vantage points above”. I previously expressed a number of concerns about the research, with the chief complaints being: 1) the methodology for placing ‘hidden’ images was poorly controlled (i.e. some images were visible to staff, giving patients a rather less esoteric means of learning about their content) and 2) the lead researcher, Dr. Parnia, was already promoting and offering dubious (quantum) interpretations about the meaning of the positive results, before the data was collected!
The study has finally been published, and despite breathless headlines such as the Telegraph’s “First hint of ‘life after death’ in biggest ever scientific study” or the Independent’s “Largest-ever study provides evidence that ‘out of body’ and ‘near-death’ experiences may actually be real”, the findings are actually remarkably unimpressive. For a start, the main finding, which is not mentioned in the abstract and quickly dismissed in one sentence in the discussion section, is that none of the 140 patients interviewed were able to identify a single hidden image. The paper tries to downplay this by pointing out that 78% of cardiac events occurred in areas without the special ‘shelves’ that held the images, this percentage however appears to be based on the full sample of 2,060 cardiac events rather than the 140 cases included in the study. It may be that the percentage is similar for these specific cases but the paper doesn’t tell us that and regardless, since the researchers seem to feel this makes the measure all but useless, you have to wonder why such a serious methodological issue was not identified as a problem in the piloting stage. Indeed, if we go back to this report from the BBC in 2009, we find a rather different take from Dr. Parnia on the importance of this null finding:
“If you can demonstrate that consciousness continues after the brain switches off, it allows for the possibility that the consciousness is a separate entity. It is unlikely that we will find many cases where this happens, but we have to be open-minded. And if no one sees the pictures, it shows these experiences are illusions or false memories.“
