Steven Novella blogs at Science-Based Medicine. Yesterday he was upset about American politicians who want to restrict research grants to projects that "advance the national health, prosperity, or welfare, and to secure the national defense" [Politics of Public Research Funding]. The goal is to put a stop to silly basic science research like studying sex in snails.
Here's the quote of the day from Steven Novella.
I have noticed, however, that researchers have become reflexively good at making up plausible-sounding possible applications for their basic science research – as if they have to constantly justify their research. Every basic-science study that looks at viruses, therefore, may one day cure the common cold. Anything dealing with cell replication may be a cure for cancer. Any materials advance will lead to supercomputers or superlight vehicles. All brain research, apparently, might one day cure Alzheimer’s disease.
I would love for a scientist to say something to the effect of “I have no idea what, if any, practical use this research might lead to, but the knowledge is really cool”. I guess you just don’t say that to a grant committee, however.
