Data and pre-registered predictions for: Emergent precision in oral traditions

Pre-registered prediction files, bathymetric results, empirical null model calibration, blind observability rater scores, and domain-level meta-analysis data supporting Allan (2026) "Emergent precision in oral traditions: cross-domain evidence that structured cultural transmission encodes measurable physical information across deep time." Round 1 predictions were timestamped before ETOPO1 bathymetric analysis. Round 2 predictions were timestamped before AusBathyTopo analysis. Blind rater scores were collected from independent respondents with no knowledge of effect sizes or the study hypothesis.
