Experiments that might appear to lend weight to, or even appear decisive for, the 'mind is generated by the brain' hypothesis cannot actually be taken to address a metaphysical decision, the crux is too far upstream. That 'materialism is true' i s a certain kind of meaning or frame for interpretation and so is a certain spiritual position. Such positions are in effect on a collective level and will give rise to results according to the historical dispensation, the status of 'science', for example, that is in effect, independently of the beliefs of an individual experiencer. Nothing here is ever fully decisive, it is always probabilities, Bayesian factors, but with nothing to say about what the priors ought to be.
