A dataset's "gold label" is supposed to be the thing a model is graded against. But where does that one label come from? For most NLI benchmarks it is derived from several human votes — and a surprising amount rides on exactly how . In two earlier audits ( SNLI #37 and MultiNLI #38, in the catalogue below) we checked whether each gold label is the strict majority of its own annotator votes. It is — but that is true by construction : the gold is defined as that majority, so the check is tautological. Reproducible and worth freezing, but not a finding.

This post is about the two cases where the comparison is not tautological: where an independent set of human judgements exists, collected separately from the label the benchmark ships. That is where you can actually learn something.
