 In SGS 2000, the CMC has more the status of an empirical posit. If \(\bV\) is set of macroscopic variables that are well-chosen, meaning that they are free from the sorts of defects described in points (ii) and (iii) above; \(\bG\) is a graph representing the causal structure on \(\bV\); and P is the objective probability distribution resulting from this causal structure; then P can be expected to satisfy MC relative to \(\bG\). More precisely, P will satisfy all three versions of MC if \(\bG\) is a directed acyclic graph, and P will satisfy MCd-separation if \(\bG\) is an ADMG with double-headed arrows. SGS defend this empirical posit in two different ways:
