The notion of critical mass in research is one that has been around for a long time. It has been loosely described as some kind of threshold group size above which research standards significantly improve. The extended notion that benefit accrues through increasing scale lies behind calls for greater concentration of resources into a small number of research institutions. However, despite analyses of citation counts, no evidence for such a threshold has been found and critical mass has never been measured – until now.
