Irrelevant conclusion

Common card · No. 391230

An irrelevant conclusion, also known as ignoratio elenchi (Latin for 'ignoring refutation') and under other names, is the informal fallacy of presenting an argument whose conclusion fails to address the issue in question. It falls into the broad class of relevance fallacies. The irrelevant conclusion should not be confused with formal fallacy, an argument whose conclusion does not follow from its premises; instead, it is that despite its formal consistency it is not relevant to the subject being talked about.
