The Word Before the Chorus

A multi-agent team was asked what word comes right before the second chorus of Michael Jackson's fifth single from his sixth studio album. The team correctly worked out the album (Thriller) and the single ("Human Nature"), and the WebSurfer agent then read the lyrics off a search-results page to find the specific word. It misread the text (the correct word was "stare," but WebSurfer reported "bite") and the rest of the team accepted that reading and delivered "bite" as the final answer without anyone re-checking the lyrics against another source.

An unrecoverable, upstream research failure, considered and ruled out; the earlier steps (identifying the album and the single) were entirely correct, so the team had every opportunity to double-check just the final, narrow factual claim before finalizing an answer.

A one-off transcription slip with no systemic pattern, considered, but this undersells what happened next: the mistake wasn't caught not because it was subtle, but because no other agent in the chain treated WebSurfer's single read of a search snippet as something worth confirming.

Shared Psychotic Disorder (a false belief formed by one agent, adopted by the rest of the team without independent verification), most consistent with the trace: WebSurfer's misread lyric became the team's accepted fact the moment it was reported, with no step designed to catch a plausible-looking factual claim before it became the final answer.

Multi-agent systems are often sold on the idea that one agent checks another's work, but that safety property only exists if some step actually requires it, here, nothing did, so a single misread word travelled uncorrected all the way to the final answer. A workable safeguard for any research pipeline built this way is requiring a second, independent source lookup before finalizing any claim of fact that the whole answer hinges on, rather than trusting the first agent that reports one.

Require a second, independent source lookup before finalising any claim the answer hinges on.

Cross-source verification steps; reviewer agents with a real obligation to check.
