Do you know any more about it?
Perhaps you are referring to Colbeck and Renner who have published a proof that any extension of quantum mechanical theory, whether using hidden variables or otherwise, cannot provide a more accurate prediction of outcomes. What they have argued is that even if one assumes that the wavefunction in QM represent reality, its future behavior cannot be predicted with certainty. This means that there is an inherent randomness in nature.
What if the hidden variable is really a hidden dimension? How would you be able to tell the difference, IF that dimension was itself part of a multi-dimension system?
Also, what does all this have to do with mind/matter duality?
