This Professor of Quantitative Science Studies argues that university rankings combine incompatible indicators. "These rankings measure in part the size of universities and in part their relative performances in relation to their size. These perspectives are then thrown into one pile. Then no one really understands what exactly the rankings are telling us." Other rankings also juggle the figures.

According to Waltman, the danger is that simplistic indicators will have a negative effect on research policy, for instance if researchers or research institutions are assessed on the basis...
