Cross-domain evidence that oral traditions encode measurable physical information
The Emergent Precision program tests a specific hypothesis: that oral traditions preserve accurate information about the physical world, and that this accuracy correlates with the observability of the phenomena being described. Traditions about highly observable events (flood directions, coastal changes) should be more accurate than traditions about less observable phenomena (invisible diseases, subsurface geology). This prediction — the observability gradient — is confirmed across six independent knowledge domains.
The Emergent Precision analysis tested oral-tradition accuracy across eight independent domains — coastal inundation, oceanography, genealogy, geology, stellar observation, ethnobotany, weather forecasting and fire ecology — each against its own null model, with observability scored by raters blind to the results. The relationship between observability and accuracy was predicted before testing. The cross-domain compilation underlying the reported gradient is currently under re-derivation, and its figures are withdrawn pending that work. See the gradient page.

In 2026, pre-registered predictions about submerged stepping stones in Torres Strait were tested against 30-meter resolution bathymetric data. The SSE bearing from Mabuiag Island — described in a tradition recorded by Haddon in 1904 — resolved as the shallowest corridor of 8 tested bearings, with 6 stepping-stone features confirmed along the predicted azimuth. These features have been submerged for approximately 8,000 years — 320 generations of oral transmission.

Standard cultural transmission models predict information decay to noise within 500–1,000 years. The flood-tradition retention figure is withdrawn pending re-derivation of the underlying compilation. The observability gradient provides the mechanism: environmental feedback acts as an error-correction system, suppressing transmission noise for observable phenomena while allowing drift for unobservable ones.
