Interactive agent-based simulation. Watch phase transitions emerge in real time as you adjust observability. Compare three models head-to-head.
Open tool
Observability Scoring Engine
Rate a traditional knowledge claim on four observability dimensions. Get a predicted accuracy score calibrated against the 16-domain empirical dataset.
Open tool
Prospective Prediction Pipeline
Input an oral tradition with geographic claims. The tool extracts testable predictions, pre-registers them, and identifies remote sensing datasets for validation.
Open tool
Convergence Tester
Input ethnographic data from multiple cultures. Compute convergence indices, run permutation null models, and test whether convergence exceeds chance.
