The best way to foster mediocrity is to found a Center for Excellence.
This is a quote from a comment by DrOFnothing on a good article by Rich DeMillo a few years back. It reminds me of my observation than shiny new research buildings often mean that the quality (but maybe not the volume) of reseach will deteriorate. This is just intellectual regression to the mean. You get the funding for the new building based on the trajectory of those who were in the old building — but with a delay. Scale, consistency and originality have a troubled relationship. Just compare the early flowerings of jazz-rock fusion (below) with the technically masterful but ultimately sterile stuff that came later.
