Would important scientists still do science at the same level of quality if all their stuff was aggressively personalized? I can think of a couple of mechanisms that might kick in. They might work harder because they feel like they have to match the help they're receiving in scientific output. But they might also take the assistance as a sign that they're great and valuable and start slacking off, like ... divas?
Also, from what I've seen/read, I think Japanese culture has this type of system for elders/experts in various fields. Maybe it applies to scientists?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
