We need a measured approach to metrics

Metrics evoke a mixed reaction from the research community. A commitment to using data and evidence to inform decisions makes many of us sympathetic to, even enthusiastic about, the prospect of granular, real-time analysis of our own activities. Yet we only have to look at the blunt use of metrics such as journal impact factors, h-indices and grant-income targets to be reminded of the pitfalls. Some of the most precious qualities of academic culture resist simple quantification, and individual indicators can struggle to do justice to the richness and plurality of our research. This article gives an overview of the findings of the UK's independent review of the role of metrics in research assessment, which published its final report on 9 July 2015.
