Could the hidden variables be encoded in the observer?

    Could the "hidden variables" be encoded in the observer?

    The hidden variables that have been proposed to dictate the action of quantum outcomes,
    Could they be in observer dependent as opposed to encoded in the particle?

    We know the observer is an integral part of the process.
    Has this idea been explored?

    Demystifier (our resident Bohmian expert) has developed such a model:

    One of the first things that drew my attention of this forum was the repetitive discussion of color perception in this particular subforum(red, blue, etc.) and how it was a subjective part of the brain(mind), and not of nature out there(I don't know why but I was always shocked by this - it could be that I was a naïve realist at that time).

    This raises a few awkward questions - just how much of all we perceive is modified by the brain?

    Is what the brain does merely a re-construction of nature out there or a co-construction of nature out there?

    The answer to that question isn't immediately obvious and delving into it has led me to consider that the answer is of the latter type.

    What is out there from the perspective of the most fundamental theory of matter we have - is waves(of probability - also called "physical matter") and frequencies(color, light, etc.). It was another shock for the naïve realist that one of the cornerstones of the new theory posits that there be a connection between knowledge and quantities being observed/measured(the so called HUP) exemplified in the DCQE experiments.

    Not so surprising, some great scientists have come to similar conclusions - neuroscientist prof. Karl Pribram and physicist David Bohm in the beginning of the 1990's. What the brain appears to do is a projection, a hologram model of the world. We consider that this projection is the world out there with 1:1 correspondence mainly because other observers agree to our observations with close to 100% accuracy(hardly surprising given that human offspring inherits the same brain structure because of the sharing of common DNA - and when we don't due to malformations, a different reality is observed - schizophrenia, etc.). But in the final analysis, it is clear that the world out there can not be 1:1 as it is experienced, it doesn't fit the experiments nor the theory. The observed and how it is prepared to be observed actually influences and to a large extent determines what will be observed. Put another way, it's not obvious how to remove the observer from what is observed as any observation, however it is defined, always forces quantum states to one of eigenstates of the corresponding operator(i.e. experience of the known classical-like world) and this sudden 'collapse' happens whenever there is information about what the system is doing.

    David Bohm went further and said that space and time were constructs of the brain, not of nature out there(nature out there seems to be a higher dimensional structure). You can read more about this here:

    You mean the mind, don't you? Using your criteria, isn't the brain itself a re-construction or co-construction, etc.?

    The brain can be scientifically studied and the mind cannot and there is a body of evidence within the current framework that mind supervenes on the brain. Of course one can question this relationship from a philosophical point of view, but that wasn't my intention with the previous post as it lies outside known science. The point is the brain can be manipulated into constructing surprisingly impressive perceptions. I believe you have seen at least once a 3D imax movie where the objects look 3D but are not or the 3D images(actually 2D) seen with anaglyph glasses?



    That 3D is a construction of the brain(your brain constructs 3 dimensions out of 2). And it's entirely 2D(this is where the idea of a holographic projection of the world within the brain comes in handy)

    I challenge the idea that 3-space and time are fundamental. There is little support for such a notion and it is a fact that that's part of how we experience the world. I think it's a problem for biology to tackle and it seems some great minds have similar ideas.

    A good question that I have also been wondering about! Yes, there is a theory that time has 3 dimensions and that the angle of two of them is fixed by the observer, whereas for the quantum object they are not fixed until a measurement is made by the observer. Here is a link to something I found today where the words are quite readable...

    Man this is an awesome post.
