But really your footnote here is hardly better off.

Given that we don’t have the requesite knowledge of brain mechanisms to be able to convincingly detail a reduction should one exist, and given also the absolutely pathetic record of claims of ontological irreducibility in standing up to informed scrutiny, postulating a fundamental nature for subjective experience at this stage in the game is more wishful thinking than honest reasoning.

And the leap from there to ‘consciousness causes collapse’ is just complete woo. It is absolutely no different from arguments people use for the alleged plausibility of psychic phenomena. Actually it would be far more surprising if the brain found a way to violate the basic linearity of quantum mechanics than if it could perform ‘mere’ FTL signaling or gravity manipulation. (Even less likely would be Penrose’s contention that it could compute outside of Turing degree 0.)
