I get a faint hint that you are yourself realising that all the various ψ phenomena can't all be mistakes/fraud/statistical faults/ etc.
Of course they aren't. That's the way I've always felt about it.
The problem is that I have no idea whether what is left looks anything like psi, or even if it does, whether it has anything but a trivial effect on the perspective of science. After all, the tidy categories of phenomena we came up with to explain "effectiveness" using folk science ("meridians", "humours", "the law of similars", etc.) turned out to have little resemblance to reality and none of what was actually going on required science to be rewritten. Similarly with "psi"...our tidy psi categories of "clairvoyance" and "poltergeists" and "telepathy", formed using folk science, don't seem likely to have much resemblance to reality. Like "effectiveness", the effects of chance, fraud and bias are so large as to overwhelm any of the more interesting effects when it comes to figuring what "psi" looks like.
That NDE's can't just be explained by saying the brain goes loopy as it dies. It is a huge intellectual jump - I know because I made it. If I'm right, then welcome to the club!

I don't know if NDE's are related to the brain going loopy as it dies, because the idea is only barely starting to be tested. I'm in the club of "maybe we should be considering tests of the idea, first".
