The filter never loosens

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Between Ptolemaic Alexandria and Byzantine Egypt the papyri witness regime change, a new empire, a new religion, and a new law of persons — yet the conjecture is that the proportion of private letters sent by women stays essentially flat across all of it. The join is between seven centuries of institutional upheaval and one invariant documentary ratio. The proposed mechanism is structural: the bottleneck on women's letter-sending was never any era's ideology but the stable machinery of who commanded scribes, travel, and letter-worthy business, and that machinery reproduced itself under every regime. If this holds, the thinness of women in the written record is load-bearing architecture rather than period fashion, every improvement narrative pinned to a particular century is sampling noise, and models of documentary survival should treat the gender filter as a constant.

Prediction clause (verbatim)

In papyri.info, the century-by-century share of securely gendered private letters with female senders (III BCE-VII CE) remains within plus-or-minus 5 percentage points of the corpus-wide mean, and a Mann-Kendall or logistic trend test finds no significant monotone trend. Primary clause: the no-trend test; the verdict follows it.

Kill-dataset (verbatim)

papyri.info: the full dated private-letter corpus with gendered senders; the kill is the statistical trend test itself.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The corpus of ~300 women's letters across a millennium is assembled and studied, and Bagnall & Cribiore's structural (social-standing) explanation gestures toward stable bottlenecks; no published century-by-century trend test of the female-sender share exists.
