 where “&gt;” means “more effective”. There is now a majority that holds that A is more effective than B (I&amp;III), a majority that holds that B is more effective than C (I&amp;II) and a majority that holds that C is more effective than A (II&amp;III). More generally, whenever there are logical relations among the propositions to be decided (in this case: \(A &gt; B\) and \(B &gt; C\) implies that \(A &gt; C\)), there are at least three panel members, and votes are aggregated by the majority rule, inconsistencies can arise at the group level (Pettit 2001).
