LongͲDistanceInterdisciplinarity LeadstoHigherScientificImpact
Larivière,Vincent,StefanieHaustein,andKatyBörner.2015.PLOSONEDOI:10.1371.
Data: 9.2 million
interdisciplinary
research papers published
between 2000 and 2012.
Results: majority (69.9%) of
co-cited interdisciplinary pairs
are “win-win” relationships,
i.e., papers that cite them
have higher citation impact
and there are as few as 3.3%
“lose-lose” relationships.
UCSD map of science is
used to compute “distance.”
