Editing False dilemma (section)

=== Deductive and defeasible arguments ===
False dilemmas are usually discussed in terms of [[deductive reasoning|deductive arguments]]. But they can also occur as [[defeasible reasoning|defeasible arguments]].<ref name="Tomić"/> A valid argument is deductive if the truth of its premises ensures the truth of its conclusion. For a valid defeasible argument, on the other hand, it is possible for all its premises to be true and the conclusion to be false. The premises merely offer a certain degree of support for the conclusion but do not ensure it.<ref>{{cite web |last1=Koons |first1=Robert |title=Defeasible Reasoning |url=https://plato.stanford.edu/entries/reasoning-defeasible/ |website=The Stanford Encyclopedia of Philosophy |publisher=Metaphysics Research Lab, Stanford University |access-date=13 March 2021 |date=2017 |archive-date=15 March 2023 |archive-url=https://web.archive.org/web/20230315044949/https://plato.stanford.edu/entries/reasoning-defeasible/ |url-status=live }}</ref> In the case of a defeasible false dilemma, the support provided for the conclusion is overestimated since various alternatives are not considered in the disjunctive premise.<ref name="Tomić"/>
