 In our example, the innocent bystander \(s\) is both a free and inevitable consequence, while \(q\) is merely an inevitable consequence. In order to highlight the defeasible character of this type of reasoning, consider the situation in which we obtain additionally the information \(\neg s\). We now have the additional two maximal consistent subsets \(\Gamma_{3} = \{p \wedge q, \neg s\}\) and \(\Gamma_{4} = \{p \wedge \neg q, \neg s\}\) in view of which \(s\) is neither a free nor an inevitable consequence. E.g., although \(\Gamma \nc_{\mathrm{free}} s\) we have \(\Gamma \cup \{\neg s\} \nnc_{\mathrm{free}} s\).
