The principle that there are no preinteractive correlations has famous connections with the most striking time-asymmetry in physics, that of the second principle that there are no preinteractive correlations between individual microsystems \micro-independence" (\�Independence", for short). accepted, but it does seem a common view in physics that Penrose and Percival's examples provide indirect observational evidence for preinteractive independence. We suppose that there is a microscopic asymmetry of �Independence, distinct from the correlations associated symmetry, this shows that �Independence is not necessary to explain the scattering observed in the usual case. we do take it for granted that there is an asymmetry in the boundary conditions of the kind required by �Independence: not because we have empirical	./cache/work_2bf4ubm6rrhabpvbtwnxnzg7kq.pdf	./txt/work_2bf4ubm6rrhabpvbtwnxnzg7kq.txt
