false_dilemma
The false dilemma fallacy forces a choice between two options as if they are the only possibilities, when in reality a spectrum of alternatives exists. It oversimplifies complex situations into binary either/or framing, often to pressure someone into choosing the option the arguer prefers. The fallacy is particularly powerful because binary thinking feels decisive and clear.
"You're either with us or against us. There's no middle ground in this fight."
A manager tells his team: 'Either you're fully committed to this project and work overtime every weekend, or you simply don't care about your career here.'
A political commentator declares: 'You either support cutting the defense budget entirely or you want endless war. Pick a side.'
A ∨ B (ignoring C, D, ...)
Binary (yes/no) questions an LLM must answer to identify this aspect:
Are only two options or sides presented?
Type: binaryAre there other viable alternatives not mentioned?
Type: binaryIs the dichotomy artificially constructed rather than genuine?

The fallacy is particularly powerful because binary thinking feels decisive and clear.
Binary framing reduces cognitive load and triggers urgency. People under pressure tend to accept simplified choices rather than expend effort identifying alternatives.
Explicitly name additional options that the argument ignores. Ask 'Why are these the only two possibilities?' to break the false binary.
Ubiquitous in political rhetoric ('you're either for freedom or for tyranny'), ultimatums in negotiations, and marketing ('buy now or miss out forever').
Relying too heavily on the first piece of information (the anchor).
I have goal G; action A achieves G; therefore I ought to do A.
Stating a controversial claim as absolute fact without acknowledging opposing views.
The accident fallacy (a dicto simpliciter ad dictum secundum quid) occurs when a general rule is applied to a specific case whose circumstances make the rule inapplicable. The fallacy treats the general rule as absolute and exceptionless, ignoring the particular features of the case at hand that constitute a legitimate exception. It is the opposite of the converse accident (hasty generalisation), which moves from specific cases to general rules.
Denying a conjunct is a formal fallacy that occurs when, from the premise that a conjunction is false (not both A and B), and the premise that one conjunct is false, it is concluded that the other conjunct must be true. This confuses the logical conjunction (AND) with the exclusive disjunction (XOR). If 'not both A and B' is true, denying A only tells us the conjunction fails — it does not tell us anything about B, which could be either true or false.
The panacea fallacy occurs when a single, simple solution is proposed as the complete answer to a complex, multi-dimensional problem. The fallacy lies not in the potential value of the proposed solution but in the claim that it alone is sufficient. Complex problems typically have multiple interacting causes, and addressing only one causal pathway while ignoring others gives the illusion of resolution without achieving it. This fallacy exploits the human preference for simple, actionable narratives over complicated, ambiguous ones.
