Predicting the results of the REF using departmental h-index: A look at biology, chemistry, physics, and sociology.

Can metrics be used instead of peer review for REF-type assessments? With the stakes so high, any replacement would have to be extremely accurate. Olesya Mryglod, Ralph Kenna, Yurij Holovatch and Bertrand Berche looked at two metric candidates, including the departmental h-index, and four subject areas: biology, chemistry, physics and sociology. The correlations are significant, but comparisons with RAE indicate that while the departmental h-index is the best metric, it would not have been good enough to replace the peer review exercise. A more important question is whether we should seek to measure research quality using metrics at all
