Take the Copenhagen interpretation of quantum physics and other consciousness-based models.
Hello, randman.
The copenhagen interpretation is not a conscious-based model. The only "conscious-based models" I have heard of are advocated by New Age advocates, but these are definitely not mainstream science.
The confusion here is understandable. The Copenhagen interpretation (and other hypotheses) speak of an "observation" causing the collapse of the wave function. "Observation" clearly brings up the idea of a conscious observer, but very, very few physicists really believe that consciousness is required to bring about the collapse of a wave function.
No one knows why or when a wave function collapses into a particular state. "Observation" is simply the term used to describe this event, but no one really knows what actually constitutes an "observation". Roger Penrose in
The Emperor's New Mind gives a sketch of some of his ideas on this, but it appeared to me to be incomplete.
