Excessive funding of star scientists harms research impact

See below an extract of a paper published yesterday in the journal Scientometrics:

“…results show that, first, there is a relatively smooth inverted U-shaped relationship between government research funding for scholars and the quality of their publications. An initial increase in government research funding positively drives the quality of public knowledge production, but the effect turns negative when research funding is excessive” https://link.springer.com/article/10.1007/s11192-022-04448-w#Sec28
