Sure. We can't even agree on a good definition for "consciousness", we certainly don't know _how_ it works. I don't think there's a lot of debate around that specific point.
I'll try and read the paper more carefully after work, but my quick read was: they posit that consciousness might not be localized in the brain because if it were, then how would people be able to perform telepathy / remote viewing / future foresight? I can't assert that their non-local hypothesis is wrong, but I can pretty confidently say that the evidence they're using to back it up is unscientific BS.
Agreed. I don’t consider what they present as “evidence”. But that doesn’t turn it into evidence against the theories either. There are other theories that explain “out of body experiences”. We just don’t know. There doesn’t seem to be convincing enough evidence to make the case for “the brain is where consciousness resides”, nor is there against it.
