 The clause   \(P_{\alpha}[c \pmid  h_j\cdot b] = P_{\alpha}[c \pmid  h_i\cdot b]\)  says that the experimental (or observation) condition described by \(c\) is as likely on \((h_i\cdot b)\) as on \((h_j\cdot b)\) — i.e., the experimental or observation conditions are no more likely according to one hypothesis than according to the other.[9]
