This paper provides a preliminary investigation towards the definition of a general framework for the comparison of extension-based argumentation semantics with respect to the notion of skepticism. We identify seven justification states for arguments and define two alternative skepticism relations between semantics, which induce a partial order on the justification states, reflecting the relevant levels of commitment.
