Deductive and defeasible arguments False dilemmas are usually discussed in terms of deductive arguments. But they can also occur as defeasible arguments. 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. 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.
