Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Archaeological, geochemical, and genetic evidence clearly shows that Polynesian populations maintained extensive and enduring inter-island contact and trade networks across the Pacific before European arrival.

The analysis

The claim is specific, empirical, and falsifiable, passing Step 0 easily. Multiple high-quality archaeological, genetic, and experimental studies (e.g., matching stone adzes across thousands of kilometers, genomic tracking of island networks, and experimental voyaging) overwhelmingly support the conclusion that Polynesians engaged in extensive pre-European inter-island voyaging and contact. There are no refuting papers.
