This entry, although titled Defeasible Reasoning, says next to nothing about defeasible reasoning. It mentions a few things which are not defeasible reasoning, and that's it. So, in other words, according to the article, it holds that:


\frac
{\{\text{is-reasoning}(x)\}\models\neg\text{as-formal-as-deductive}(x), \neg\text{inductive}(x), \neg\text{retroductive}(x)}
{\{\text{is-reasoning}(x)\}\models\text{defeasible}(x)}

Is defeasible reasoning such a broad term? Perhaps some examples are in order.

Since the subject of nonmonotonic logic was approached, how is defeasible reasoning/logic different from / like nonmonotonic logic? It is, for instance, my impression that circumscription, default logic, and autoepistemic logic are all nonmonotonic in nature.
