A thousand times yes. You can’t publish 40 papers a year and have thought at all deeply about each one. And you can’t run a massive, impersonal lab and produce happy researchers who want to stay in science. The work and the workers suffer. Do less, better!
Great piece on prioritizing quality over quantity in scientific publication.
For those of us with labs, this necessarily involves shrinking our group size. After I got tenure I started to downsize my lab and have not regretted it one iota. More time for each student & more time to think & write.

I’m going to halve my publication output. You should consider slow science, too
If we don’t slow down, the research enterprise is going to crash, argues Adrian Barnett.
