My ScienceBlogs sibling Kevin Vranes asks an interesting question (and provides some useful facts for thinking about the answer):
Why do we even spend taxpayer money on basic science research? Is it to fund science for discovery’s sake alone? Or to meet an array of identified societal needs?
The original post-WWII Vannevar Bush model was that the feds give money to the scientists for basic research, the scientists decide how to allocate that money, and society gets innumerable benefits, even if a direct link can’t be made between individual projects and economic growth.
But it turns out that of all the American taxpayer cash spent on S&T R&D, only a small portion goes to the agencies engaged in basic science research. About 55% goes to defense R&D and 20% to NIH (see chart). The National Science Foundation, the flagship of basic research for the U.S. government, gets only 3% of all federal R&D funds.
The first thing to notice is that we taxpayers aren’t spending all that much on basic research. So quit telling the guy down the street with the NSF grant that he’s working for you. Most of what we’re funding, based on these numbers, is the defense of our bodies by modern medicine and the military. (Yes, there’s maybe some offense in the defense R&D.)
But the more interesting question, to my mind, is whether there are persuasive reasons for funding more basic research than we do — or, for that matter, for funding it all all.
