Then we should privatize research grants more then if that’s the issue cause government subsidized things never can truly be “free” as the government has to actively choose which grants to approve and which not too .
That decision is usually made by people who do have political agendas as well so the this will mainly just provide more oversight over unelected bureaucrats which I generally support.
Major grant decisions (at places like NIH and NSF) are made by scientific peers, not by "unelected bureaucrats". It depends on the agency, but a few faculty send our scores in to someone working at the agency. The scores are based on rubrics that are available to anyone and tend to prioritize (1) general academic merit and (2) something specific to the agency (for the NIH, health outcomes; for NSF, "broader impacts", which is generally some sort of community impact or public science education). Critically, the "someone" (usually called a program officer) is someone who has also had academic training and probably has received several grants themselves at some point; it's seen as prestigious, if tedious, to become a program officer. The highest scoring proposals are then discussed as a bunch of peers, and the grants are ranked. Depending on the agency, the program officer may have a bit of discretion for grants that fall right on the boundary of being funded, but again it's based on the same criteria I outlined above.
Only about 10-15% of major grants are funded. I'd say the main issues with funding these days is that (1) one-in-ten isn't a great level of success, so you're incentivized to chase the funding obsessively rather than following the science, and (2) it's often the case that the rich get richer (e.g., you generally need pilot data to get a grant funded these days, but how do you get pilot data if you don't have money in the first place?). The amount of interference from "unelected bureaucrats" is small unless you consider faculty members to be "unelected bureaucrats". (But I think we'd all agree it would be bonkers for
elected officials to evaluate scientific grants, right?!) Even then, the folks working at the funding agency aren't just random people with political agendas, they're usually scooped up from tenure-track positions by the NSF or NIH.
