Comment Side effect of grant structure (Score 3, Interesting) 123
Grant money is given preferably to teams that already publish a lot. Even "starting grants" in the EU require a single principal investigator (PI) with a lot of well-cited publication under their belt. This can only be achieved if the PI has done their initial research in a well-heeled lab, with a well-known head of the lab who is well-connected, and so on. This encourages a pyramidal structure with a lot of grunt students at the bottom, supervised by post-docs, supervised by assistant professors, and so on. Success encourages visibility, which encourages grants, which ensures money, which ensures good grunt students can be hired, and so on.
This is not the only possible successful structure, but one of the most common. A single researcher, however brilliant, cannot usually keep up with the outpouring of landmark papers the pyramidal structure can achieve. On the other hand, if everybody does their job, meritocracy in the pyramidal structure ensures that the best grunt students get promoted to post docs, and so on, usually in a different pyramidal structure.
The big drawback of the pyramidal structure is that the prof at the top usually doesn't know exactly what is going on at the bottom, even though they put their name on most of the papers that the structure produces.
Disclaimer: I'm a tenured prof. I do have a reasonable number of students, but I work with them directly. All my students are co-supervised with at least one other prof. Occasionally I do have a few post-docs but the structure is always collaborative. This is not the standard but this works well enough also as long as there isn't any ego-driven fights in the lab. This means choosing your collaborators well. I've made a few mistakes, but so far so good.
