![]() ![]() ![]() When the premise of mutual exclusivity is false, this means that it involves presenting the available options in a way that suggests that we can only choose one of them (or that only one of them can be true), while in reality it’s possible to pick two or more of them (or for two or more of them to be true). In this context, mutual exclusivity means that only one of the available options can be selected (or can be true) at any given time. False dilemmas contain at least one of the following false premises: Here, the premise that “natural” things are necessarily good for you is false, since there are many “natural” things that are bad for you, such as cyanide, which is a deadly toxin that’s produced naturally by some plants.Īnother example of false premises that stand at the core of a logical fallacy appears in the case of the false dilemma, which is a logical fallacy that occurs when a limited number of options are incorrectly presented as being mutually exclusive to one another or as being the only options that exist, in a situation where that isn’t the case. In addition, further examples of false premises appear as part of various logical fallacies.įor example, the appeal to nature is a logical fallacy that can involve claiming that something is good because it’s “natural”. However, this doesn’t mean that the conclusion of the argument is necessarily false, since even fallacious arguments can have true conclusions, which means that it’s possible that it did indeed just rain. ![]() For example, it’s possible that it rained hours ago and the street didn’t dry, or that a fire hydrant broke and sprayed water everywhere.īecause this argument relies on a false premise, it can be considered logically unsound. Here, premise 1 (“If the street is wet, then it just rained”) is false, since if the street is wet, that doesn’t necessarily mean that it just rained. Premise 1: If the street is wet, then it just rained. An example of a false premise is “all swans are white”, which can appear, for instance, in a logically unsound argument such as “all swans are white, so if an animal is black then it isn’t a swan”.Īnother example of a false premise appears in the following syllogism (a form of reasoning where a conclusion is drawn from two premises): ![]()
