All I知 trying to point out is that one of the many counter arguments that opponents of the argument from religious experience use is not as strong as it would first appear as the argument can be run the both ways. If hallucination, suggestion, mental illness etc. can cause people to see things that are not there then is it not possible that they can cause people to not see things that are there?
I don't think this argument works.
We're back to the CR/NCR thing. Consensual reality is the construct of the majority of people, whose experiences are compared with each other. If you like, the lowest common denominator of experience. Non-consensual reality, OTOH, is not a single construct of those who experience CR plus something else. Those who experience NCR experience in a wide variety of ways, most of which do not converge to produce a standard NCR. Consequently, where those experiences differ as much from each other as they do from those who only experience CR, are we to say that there is one form of NCR and all the other claimants are as unattached to some sort of 'true' reality as are those who experience only CR? Or do we say there is some means of reconciling these differences? Or that the 'true' nature of reality is total chaos? You would, after all, have to include the genuine psychotics in there.
The point is that 'reality' is owned by us all - both those whose experience is only CR and those who also experience NCR. Excepting only those who experience psychosis which, in many ways, is only a way of saying they have lost touch with CR in certain ways which produce set symptoms. If you redefine NCR as true 'reality' then there is the danger that 'reality' ceases to mean anything at all.
I realise you may be trying to say that some people may not be able to experience NCR and that there may be something 'not there' which is 'there' for other people who do experience it, but, even taking that analogy and running with it, surely an 'anti-hallucination' would temporarily deprive someone otherwise capable of experience NCR of that ability? I don't see how one condition or the other would make any difference to a person's susceptibility to suggestion (read, for example, Asch's experiments, which ground susceptibility to suggestion in social plasticity rather than mental aberration), and mental illness can strike anyone and does not necessarily result in any form of NCR.

Also , say for example you did an experiment to determine whether or not magic exists, how do you determine that the results you perceive are the actual results and not some hallucination?
Hmm...if we take that line then I'd suggest we cannot depend on anything as a means to test 'reality'. Perhaps an experiement with gravity might be worthwhile.
