False Dilemmas and False Dichotomies: What They Are and How to Respond to Them

False Dilemma


A false dilemma (or false dichotomy) is a logical fallacy that occurs when a limited number of options are wrongly presented as being mutually exclusive or the only available options. For example, a false dilemma occurs when someone says that we must choose between options A or B, without mentioning that we can pick both or that option C also exists.

False dilemmas often play a role in people’s internal reasoning process, when they misunderstand or misinterpret situations. Furthermore, false dilemmas are also frequently used intentionally for rhetorical purposes in various ways, such as to oversimplify complex situations by turning them into misleading dichotomies, or to frame issues in a way that pressures people to accept a certain stance.

Because false dilemmas are so prevalent and potentially powerful, it’s important to understand them. As such, in the following article you will learn more about false dilemmas, see some examples of their use, and understand what you can do in order to counter them successfully.


Understanding false dilemmas

The false dilemma is an informal fallacy, since there is an issue with its premises, and namely with the assumption that both of the following conditions are true, in a situation where one or both of them are false:

  • A false dilemma assumes that the options that are presented are mutually exclusive. In this context, mutual exclusivity means that only one of the available options can be selected (or can be true) at any given time. Accordingly, if a false dilemma occurs as a result of incorrectly assuming mutual exclusivity, then that 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).
  • A false dilemma assumes that the options that are presented are collectively exhaustive. In this context, collective exhaustivity means that the options that are presented are the only ones that are available. Accordingly, if a false dilemma occurs as a result of incorrectly assuming collective exhaustivity, then that means that it involves presenting a limited number of options as the only available ones, while in reality there are other relevant options that are being ignored.

Based on this, a false dilemma can also be said to be fallacious because it incorrectly assumes that the different options which are mentioned represent an exclusive disjunction, which means that out of the options which are presented, one, and only one, must be true (or must be picked). This ignores and hides the fact that it’s possible for multiple propositions to be true at the same time, or that it’s possible for other propositions, which aren’t mentioned, to also be true.

However, note that since the term ‘disjunction’ refers to situations where there are only two options being presented (i.e. a dichotomy), it does not apply in situations where a false dilemma presents three or more options.


Relationship between false dilemmas and false dichotomies

The terms ‘false dilemma’ and ‘false dichotomy’ are often used interchangeably with one another, without making a distinction between the two.

However, it’s possible to view the false dichotomy as a specific type of false dilemma, where only two options are presented.

Under this view, the false dichotomy is the most common type of false dilemma, since it represents its simplest and most compelling form. This is reflected in the fact that, as noted above, this term is often used interchangeably with ‘false dilemma’. Furthermore, this is also reflected in the many names that are used to refer to the false dichotomy, including false binaryblack-and-white thinking, the black-or-white fallacy, the bifurcation fallacy, and the either-or fallacy, as well as other names that refer to specific types of false dichotomies, such as the fallacy of false alternative and the fallacy of the excluded middle.

Some philosophers make a different distinction between false dichotomies and false dilemmas, by claiming that a false dichotomy is a belief, while a false dilemma is an argument, which can either be used intentionally or as a result of people’s belief in a false dichotomy.

Overall, however, this difference in terminology is not crucial from a practical perspective, and the important thing is to understand this type of fallacious reasoning, and recognize the fact that it can appear both as a belief as well as as an argument.

Note: false dilemmas in general and false dichotomies in particular are sometimes referred to as horned syllogisms, as they represent a type of syllogism (a common form of reasoning where a conclusion is drawn from two premises), where the opponent is meant to be ‘impaled’ on one of the possible options that they are presented with.


Examples of false dilemmas and false dichotomies

The following is an example of a false dilemma (which in this case is also a false dichotomy):

“You’re either with us, or against us.”

Here, the false dilemma uses divisive language, in order to present a misleading dichotomy, which ignores the possibility of having mixed or neutral feelings toward the speaker. This dichotomy is used in order to pressure listeners into accepting a certain stance (being ‘with’ the speaker), by suggesting that there is only one alternative, which is framed in a negative manner.

A similar example of a false dichotomy is the following:

“Either you support this law which will give the police more power, or you must be a criminal.”

Here, the false dichotomy makes it appear as if anyone who opposes the proposed law must be a criminal, by ignoring the reasonable possibility that people might oppose the law for other reasons, to pressure listeners into accepting it.

This example also demonstrates how false dilemmas are often combined with other techniques and fallacies, to magnify their rhetorical effect. Specifically, in this case, the false dilemma can be said to be a part of an ad hominem argument, which is meant to attack an opponent directly, instead of addressing the stance that they are arguing for.

Finally, note that both of the above examples include an either-or statement, which commonly appears as part of false dilemmas. However, false dilemmas can also be formulated without such language. For example, consider the following statement:

“The choice is simple: if you want better salaries for low-level employees, we will have to significantly increase prices, which will hurt consumers.”

This statement falsely dichotomizes the issue at hand, by pretending that there are only two possible options to choose from, in an attempt to make it seem as if the opposing stance (increasing employees’ salaries) will have to come at the expense of increased prices. However, there are other options that aren’t mentioned here. For example, it might be possible to get the necessary budget by reducing the company’s profit margins, or by taking the necessary budget from somewhere else.

Similarly, some false dichotomies are established through the use of words such as ‘rather’, as in the following example:

“Censorship laws are not tools for suppressing the population, but rather for preventing crime.”

The use of the word ‘rather’ in this form has been described by philosopher Daniel Dennett as rathering, which he says is “a way of sliding you swiftly and gently past a false dichotomy”. The issue here is that the term ‘rather’ is used in order to subtly establish the idea that the two options which are presented are mutually exclusive, in situations where that isn’t the case. As Dennett says:

The general form of a rathering is “It is not the case that blahblahblah, as orthodoxy would have you believe; it is rather that suchandsuchandsuch—which is radically different.”

Some ratherings are just fine; you really must choose between the two alternatives on offer; in these cases, you are not being offered a false, but rather a genuine, inescapable dichotomy.

But some ratherings are little more than sleight of hand, due to the fact that the word “rather” implies—without argument—that there is an important incompatibility between the claims flanking it.

How to respond to a false dilemma

There are several ways to respond to a false dilemma in order to counter it, most of which focus on proving why such an argument is logically unsound. The two main ways to accomplish this revolve around explaining why the dilemma in question is false in the first place:

  • Refute the premise of mutual exclusivity. Specifically, explain why two or more of the available options can both be selected (or be true) at the same time, which shows that they aren’t mutually exclusive. For example, if the false dilemma suggests that your feelings toward someone can be either positive or negative, explain that it’s possible to have mixed feelings. This method is known as escaping between the horns of the dilemma.
  • Refute the premise of collective exhaustivity. Specifically, provide a counterexample which shows that there are additional options beyond the ones that were presented. For example, if the false dilemma includes only two options, show that a third alternative is also possible. This method is also known as escaping between the horns of the dilemma.

In addition, you can also counter a false dilemma by refuting the validity of one of the options that it contains. For instance, if the first proposition in a false dichotomy is wrong in some way, demonstrating this could, in some cases, negate the core of the argument, despite the fact that it doesn’t involve pointing out why the dilemma itself is false. This method is known as grasping the dilemma by the horns.

For example, this approach could be used to counter the following false dichotomy:

“Our political party is the only one that cares about making this country better. You can either support us, and try to do the same, or you can support the other party, which will only make this country worse.”

Here, one way to respond is to refute one or more of the underlying premises which are used in the false dichotomy, and namely the idea that party A is the only one that cares about making the country better, or that supporting the other party will only make the country worse.

Finally, a method that may sometimes be used to respond to rhetorical dilemmas, whether they’re false or not, involves rebutting a dilemma by means of a counter-dilemma. This involves presenting an opposing dilemma, which uses similar options as the original dilemma, but which reaches a different conclusion.

A classic example of this approach appears in a story where an Athenian mother attempts to persuade her son to not enter politics, by presenting him with the following dilemma:

“If you say what is just, men will hate you; and if you say what is unjust, the gods will hate you. But you must either say one or the other; therefore you will be hated.”

The son rebutted this dilemma by presenting a counter-dilemma, which takes the same options and comes to a different, more positive conclusion:

“If I say what is just, the gods will love me; and if I say what is unjust, men will love me. I must say either the one or the other. Therefore I shall be loved.”

In this case, both the dilemmas which were presented are sound, from a logical perspective, and the counter-dilemma approach can be used both when a dilemma is false, as well as when it isn’t. This is because the goal of this approach isn’t to refute the opponent’s argument directly, but rather to simply present an opposing argument that is compelling from a rhetorical perspective.

Note: The term ‘escaping between the horns of the dilemma’ is used to refer to any technique that involves refuting a false dilemma by addressing its premise of exclusive disjunction. As such, it refers both to techniques that address the premise of mutual exclusivity, and to those that address the premise of exhaustive collectivity, as noted above.


When false dilemmas are used together with other fallacies

People who use false dilemmas often combine them with other logical fallacies, such as strawman arguments, which involve misrepresenting an opposing view, or appeals to emotion, which involve presenting misleading arguments to manipulate people’s emotions. A common example of this is when people exaggerate the characteristics of the two sides in a false dichotomy, in order to make their favored side appear more positive, and make the opposing side appear more negative.

This is important to keep in mind, for several reasons:

  • The use of additional fallacies provides clues into people’s reasoning process. As such, it can help you identify cases where they’re using fallacious reasoning unintentionally, because they misunderstand the situation at hand, and can help you figure out what this misunderstanding is based on.
  • The use of additional fallacies affects the way other people perceive the false dilemma. This means that, if you want to accurately understand how an audience will react to the fallacious argument, and whether they will be persuaded it by, you must take into account the use of these additional fallacies.
  • The use of additional fallacies affects the way in which you should counter the false dilemma. Because these fallacies can play such a critical role in the way people perceive the false dilemma, in many cases you have to take them into account in your response, and you might, for example, have to respond to them directly before countering the dilemma itself.


Caveats about false dilemmas

There are two important caveats you should keep in mind when responding to a false dilemma:

  • Not every dilemma is a false dilemma. In some cases, a dilemma or a dichotomy might be entirely valid, and you shouldn’t automatically assume that every dilemma that you encounter is fallacious. If you’re unsure whether a certain dilemma is false, examine its underlying premises, and check whether its assumption of mutual exclusivity and collective exhaustivity is reasonable or not.
  • Not every use of a false dilemma is intentional. People often use false dilemmas unintentionally both in their internal reasoning process, as well as in their arguments. This is important to keep in mind, because it means that you could be using false dilemmas yourself without being aware that you are doing so, and because you need to account for this when you respond to someone’s use of a false dilemma.

In this regard, a good concept to keep in mind is the principle of charity, which denotes that, when interpreting someone’s statement, you should assume that the best possible interpretation of that statement is the one that the speaker meant to convey.


Summary and conclusions

  • A false dilemma (or false dichotomy) is a logical fallacy that occurs when a limited number of options are wrongly presented as being mutually exclusive or the only available options.
  • For example, a false dilemma occurs when someone says that we must choose between options A or B, without mentioning that we can pick both or that option C also exists.
  • The main way to counter a false dilemma is to point out its logical flaw, by demonstrating that the options it includes aren’t mutually exclusive or aren’t the only available options.
  • You can also respond to false dilemmas by pointing out issues with the options that they present (e.g., if one of the options is unreasonable), or by presenting a counter-dilemma that involves similar options but comes to a different conclusion.
  • When preparing to respond to a false dilemma, remember that not every dilemma is false, and that not every use of a false dilemma is intentional.
