Bornmann L. Measuring the societal impact of research. EMBO reports 2012;13(8):673-676
While research is less and less assessed on scientific impact alone, the increasingly important contributions of science to society should be quantified. The problem begins with defining the "societal impact of research" and how to evaluate societal quality. Research into societal impact is still in the early stages: it is much harder to measure than scientific impact, and there are probably no indicators that can be used across all disciplines and institutions for collation in databases. Societal impact often takes many years to become apparent.
