However, before hospitals starting doing this I already knew. There is no evidence that consciousness persists after death. Not a single dead person has communicated with the living. It's simple really.
Not actually true, theres a shed load of evidence out of there for after-death communication. I wouldnt say its conclusive, but theres certainly enough compelling evidence out there.
Look at something like the Enfield haunting.

You have all sorts of people - psychologists, journalists, policemen, next door neighbours confirming the poltergeist activity.
In those sorts of cases you come to a junction where it actually requires far more faith to believe that something valid and external 'didnt' happen than to conclude that it did.
Having said that as its been pointed out in that case you could be dealing somesort of psychokinetic activity rather than something beyond death.
Either way, its another instance of the truely anonamous that doesnt really tally up with prosaic explainations.
I am not disputing audio. Dying people whom are conscious can apparently hear things sometimes. It's the floating overhead as some kind of disembodies soul that is utterly hallucinatory... and proven to be so via those hospital experiments.
Isolated incidents of OBEs have shown that the OBE imagery 'does' match up with the actual ongoing events in the theatre from time to time though.
Thats what makes OBEs so perplexing, some of the data just doesnt match up 'atall' with reality and some of it does - with eerie accuracy.
Id posit that OBEs are some sort of 'inbetween' state of fantasy and reality personally.
In either case, and what ever they may be these experiences are definitely hard-wired into the brain/mind it seems.
Jesus H. Christ. Science is a tool. It's a freakin' process and NOTHING MORE. Consciousness is SELF EVIDENT. In other words the 'what' is there and people are using science to understand the 'how' / 'why'. You cannot really apply science to a 'what' that is non-existent... there has to be something 'real' to study.
Well this is what me and Grover are trying to get across here (sorry to butt in here by the way) the 'what' is still highly contestable.
At the most extreme end you have quantum particles setting a divide within philosophy and science - some claim their self-agency and their demonstration of reciept and transmission of information is enough to constitute consciousness.
Others believe that there must be some sort of 'higher' expression of subjectivity for us to label them as conscious.
