The expression \u201cnon sequitur\u201d means \u201cit does not follow\u201d in Latin. Although the term was originally used in the context of philosophy to refer to bad logic, today it is used more broadly for any type of statement that seems to come out of nowhere.<\/p><p>A non-sequitur is a formal logical error because the error lies in the structure of the argument. More specifically, there is a logical gap between the premise or evidence provided and the conclusion drawn from it. Even if everything is verified and true, the logic between each element is not present.<\/p><p>A non sequitur argument is characterized by reasoning or evidence that is completely unrelated to the claim being made. Non-sequences have the following characteristics:<\/p><ul><li>These are declarations which do not provide any information in relation to the <a href=\"https:\/\/guillaume-guerard.com\/en\/cours-de-methodologie\/definir-les-questions-scientifiques\/\">question<\/a> or to the previous declaration.<\/li><li>These are not just random statements.
