Van Noorden R. Interdisciplinary research by the numbers. Nature 2015 September 16;525(7569):306-7
Interdisciplinary work is considered crucial by scientists, policy-makers and funders. This study reveals the extent and impact of research that bridges disciplines.The fraction of paper references that point to work in other disciplines is increasing in both the natural and the social sciences. And although papers that combine very disparate fields tend to have fewer citations, interdisciplinary work can have broad societal and economic impacts that are not captured by citations.
