Dear LizR, You lost me. Why are you and others so wedded to local realism?
"The arguments against realism in QM critically assume "Bell's fourth assumption" - that there is some underlying time asymmetry built into physics. If one throws out this (so far unproven) assumption, it become logically possible to explain violations of Bell's inequality while preserving realism and locality." Umm, thermodynamics... Sure, our mathematical models of physical laws are such that they are piece-wise time symmetric, but a mountain of paper has been used arguing that micro-reversibility of physical laws does not support local realism. I invite you to read Donald Hoffman's paper on perception. http://www.cogsci.uci.edu/~ddhoff/interface.pdf He makes a very good case that Nature does not select for truthful 1p content, it selects for content that maximizes fitness. Local realism is yet another figment of our imagination, IMHO.
