This is a roundabout and unfair way to try to force research to 'prove' worth to politicians. NSF research has to show importance to a committee trained in these scientific areas anyway before money is awarded and isn't that where we should leave it - with a panel of experts in the field who know best? Believe me, I have had an NSF and you *must* point out why it is important and what broader impacts the research will have - including how it can help people here in the US. We often do not know exactly how it will benefit only US citizens, but how narrow minded we are if we can't consider some broad impacts to those outside of the US. No matter what Rep. Smith or Sen. Paul say about waste - it's a very small percentage of a budget where the majority of money goes to military spending.
