Are there any downsides to sharing a successful proposal with others? Since being awarded a grant from NSF (my first!) I have received a few requests from strangers at other universities, who are themselves seeking funding, to see a copy of my funded proposal.  Initially I reacted negatively to these requests, thinking that somehow the "secret sauce" of the successful proposal would be weakened by sharing it.  However, I now feel that sharing a funded proposal has the following benefits:


It increases my work's exposure and may lead to complementary research by another group;
It may lead to an opportunity for collaboration.


The major downside is the prospect of plagiarism-- that the stranger would use my text in a publication.  Of course I am planning to do that, but they should not since I would probably find out sooner or later.

If it is appropriate to share funded proposals, then the next logical step is to make the entire proposal entirely public.  Here it seems like there is significant opportunity to weaken my chances of getting future funding-- but I can't say exactly why I feel that way.

What do other SE readers think of this?  This may be appropriate for community-wiki.

Funded NSF proposals are requestable directly from NSF through the Freedom of Information Act. Proposal authors are given the opportunity to suggest redactions to NSF of proprietary or other information that should not be disclosed generally, but their FOIA office has final say on what gets sent. This kind of information might include not yet released product specs that would be bought with the grant funding or salaries of non-public employees. I suspect that all non-classified US federal agency grants are FOIAable through a similar process, but I only have FOIA experience with NSF.

Some people put their successful grants online, some people keep them secret. Your special sauce, in the end, is probably not that special, but good writing and good organization may be informative to weaker writers in the world. We don't publish our grant application texts online, but they're definitely out there due to FOIA.
