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

Historical and archaeological evidence indicates that Norse contacts with North America were limited and sporadic, lacking the massive, transformative biological and cultural exchange characteristic of the Columbian Exchange.

The analysis

The claim posits a historical 'Viking Exchange' analogous in scale and impact to the Columbian Exchange. However, scholarship on Norse contact with the Americas (e.g., Park 1984; Rooney et al. 2024) emphasizes that interactions were localized, intermittent, and had no major, lasting influence on the populations or environments of the New World, directly refuting the idea of a parallel to the Columbian Exchange.
