    Since QM methods always reference the experimental setup, it would be a very bold assertion to claim that it says something about consciousness. That would seem to imply that our QM formalisms encapsulate consciousness. Although this also, technically, means that the whole system, including experimental apparatus, remains in a superposition until itself interacted with.

    It has become very hard to separate pseudoscience from the actual investigations into what part quantum processes may play in things like the interaction at the synaptic cleft.

    Kenneth Krane's Modern Physics gives a statistical interpretation of uncertainty, and points out that there are uncertainty relations for classical waves.

    The statistical reason that \( \Delta x \Delta p = \frac {\hbar} {2} \), is the same reason that a wavepacket with minimal uncertainty (e.g. one confined to a one-dimensional potential well) has \( \eta = \frac {1} {4\pi} \) where \( \eta \) is the statistical uncertainty (in say, the wavelength, or perhaps the energy).

    Hence my remark about radio engineers earlier.

    Yes I believe it's called the double slit experiment which proves things are in two places at once. Without all alternate realities this one could not exist.
