Near death experiences are a tricky thing to study. There are physiological explanations for much of it, such as weird brain activity is likely to be interpreted as a weird experience.
These people would have no way of having knowing this stuff unless they’ve seen it for themselves, which would have been physically impossible.
The problem of this argument is confirmation bias. An anecdote of seeing information you couldn’t have seen and being right is going to be more memorable than seeing information and being wrong.
when you have several hundred of them compiled back-to-back-to-back it becomes harder and harder to find the willpower required to muster up a skeptical response
The scientific method involves looking at both the cases where it seems like something happened and the cases where nothing happened (e.g. someone said they had an experience but it clearly didn’t match reality). If you cherry pick just the events that “showed” what you want, that’s confirmation bias.
I did some googling of my own and found some studies on the topic from seemingly reputable sources that suggested physiological explanations might not be sufficient to explain the patterns they saw. Several of these had the same first author. I also found plenty of studies suggesting physiological explanations can be sufficient, as well as some specific criticisms of the couple studies that suggested they weren’t sufficient.
It’s interesting for sure that there is a doctor or two who seem to believe in the supernatural. The topic of near death experience seems to be of research interest regardless of any supernatural theories because of what it tells us about the brain.
It seems we will likely arrive at scientific consensus about near death experience in the future. I wouldn’t hold my breath that supernatural theories will survive that process.
events that transpired when they had no brain activity.
I think I saw the case this was talking about during my googling. It said “brain activity was not expected” which is not the same as “there was no brain activity”.
That’s the problem with a book like the one you are describing. It’s deliberately cherry picked, exaggerated, and biased to drive you to a certain conclusion.
I instead urge you to go read scientific papers on the topic, and specifically not just the ones that seem to suggest the outcome you want to hear.
