A false dilemma (also called the fallacy of the false alternative, false dichotomy, the either-or fallacy, fallacy of the excluded middle, fallacy of false choice, black-and/or-white thinking, or the fallacy of exhaustive hypotheses) is a type of informal fallacy that involves a situation in which limited alternatives are considered, when in fact there is at least one additional option. The options may be a position that is between two extremes (such as when there are shades of grey) or may be completely different alternatives. The opposite of this fallacy is argument to moderation.
