Methodology

Every article in the program follows the same protocol: source aggregation, normalization, anomaly detection across four layers, manual cross-check, and publication only when the evidence threshold is met. We document the full methodology — what we measure, how we verify, what we exclude.

The Dataset

Colosseum Tour Research Corpus 2026 is the evidence base behind every article in this program. It aggregates publicly available data from seven independent sources, normalized into a single analysis-ready corpus, and covers two stages of the journey: the deliberation before booking and the verdict after visiting.
