Identify the flaw in the argument: “Everyone on my mother’s side of the family loves baked mac and cheese. So, since Justin Theroux is not on my mother’s side of my family, he must not like mac and cheese.”
This is the fallacy of the inverse. Whenever an argument gives you a conditional statement, then gives you the opposite of the sufficient condition and tries to use that to conclude the opposite of the necessary condition, it commits an inverse fallacy. In this example, even if Justin Theroux is not in my family and thus does not fulfill this sufficient condition for liking mac and cheese, he may still like mac and cheese for some other reason. So we cannot say definitively that he does not like mac and cheese.
