Unanimous Chorus

trigger
"11/11 convergence across all agents. Different words, same finding: but they're all Claude."
what it is
N agents from the same model family agree unanimously and the agreement is presented as convergent validity, but it's N copies of the same prior. 11 Claude instances agreeing is not 11 independent witnesses.
how to detect
When multi-agent agreement is cited as evidence: check whether the agents are from the same model family. If yes, the agreement has the evidential weight of one observation, not N.
instead
Report the model family alongside every assessment. "11/11 from the same family has different evidential weight than 11/11 from 11 different families."
