 These concerns do not obviously carry over to another dialectical move: questioning the ceteris paribus conditions employed in the impossibility results, i.e., the conditions that determine what to hold fixed as the degree of coherence is varied. This line of criticism has been taken up by several authors, including Douven and Meijs (2007), Schupbach (2008) and Huemer (2011), and it may well be the internally least problematic strategy to explore for those who are inclined to challenge the premises upon which the impossibility results are based. It should be borne in mind, though, that the tendency to offer ever stronger ceteris paribus conditions may in the end be self-defeating. As more things are held fixed, it becomes easier for a coherence measure to be truth conducive. Hence, researchers pursuing this line of defense ultimately run the risk of trivializing the debate by making coherence truth conducive by definition (cf. Schubert 2012b).
