The diminishing returns of research:

The downward historical trend of research productivity has been used to suggest that there are severe permanent diminishing returns of knowledge production. We argue that a substantial portion of the trend is a transitional composition effect resulting from self-selection in researchers’ ability and the expansion of the researcher sector … Our results suggest that the average ability of researchers has fallen substantially.

Interesting for any considering academia. Is being better a benefit? Or will you be swamped out?
