False dilemma is a logical fallacy, or a flaw in reasoning that weakens an argument, in which someone offers a limited number of options when more options exist. It’s a common type of error in various types of debates and discussions — from politics and media to our everyday conversations.

It’s sometimes called “false dichotomy”, although technically, this can be seen as a specific, slightly different type of fallacy.

What Is a False Dilemma?

✍️ A false dilemma occurs when a limited number of choices, outcomes, or views are presented as the only possibilities when, in fact, more possibilities exist. As such, it unjustifiably puts issues into black-or-white terms.

Accordingly, it’s also known as the either-or fallacy, all-or-nothing fallacy, and black-and-white thinking.

💔 A simple example would be:

“You either love me or hate me”.

This is a false dilemma as there are other emotions people may feel for each other than just these two extremes.

Essentially, this fallacy can be committed in two ways: by suggesting that there are only two possible options when more exist, or by incorrectly presenting the choices as mutually exclusive (only one of the options can be true). Also, one of the given options is often clearly undesirable, while the other one — which the arguer may want us to choose — seems acceptable and rational.

Furthermore, it’s frequently characterized by “either-this-or-that” type of language, implying that if one of the choices is true, the other one must be false, or if you don’t accept one, the other must be accepted. In reality, however, both of the options may be false or could be accepted at the same time.

Why It Occurs

This fallacy is typically committed because one fails to take into consideration other possible options that would apply to the issue. This can be due to carelessness or, as it sometimes is, a deliberate persuasion strategy by the arguer.

As D. Q. McInerny noted in his book Being Logical: A Guide to Good Thinking:

The fallacy seeks to create a false sense of urgency in an audience, to force them to choose between the alternatives carefully selected by the perpetrator of the fallacy.
