Claim

Small and fragmented research fields likely suffer more from missed cross-disciplinary citations than large fields do, because fewer researchers act as bridges between adjacent domains.

Reasoning

In mature fields, core papers are widely known and social networks often compensate for incomplete literature review. In smaller fields, however, important methods or analogous findings in neighboring domains may remain invisible for years. AI-assisted literature mapping could reduce this by surfacing structural similarities across disciplines rather than relying only on keyword overlap.

Test

Compare two matched groups of researchers working in small fields. Give one group standard search tools and the other AI-generated literature maps that highlight conceptually adjacent work from outside the immediate field. Measure whether the second group identifies more relevant non-obvious citations and produces more novel experimental designs.

Limitation

This only helps if the maps improve signal rather than flooding researchers with plausible but irrelevant links.
