I'm curious if people have a feel for the differences between various NSF panels or even between NIH study sections. My NSF experience has been in a single organization in the BIO directorate. Really, within a single program. I may have the opportunity to serve on a panel in a different BIO organization, but it is worth it?
Are the differences enough to warrant the work or do all panels basically run the same, with the variation unlikely to matter all that much? What about NIH study sections? Have people noticed a difference between different study sections? Is the broadening of experience worth reading all those grants?
