As a random example of inefficiency: there's a lot more money going into research on specific degenerative diseases than into the causes and solutions for degeneration. Solve the root cause, not the symptoms.
Neurodegeneration is a pattern of response to multiple disease processes - we can only understand the response by studying the cases in which it arises.
For the tech-minded crowd, this is like wanting to create responsive designs without actually making websites to demonstrate them.
The NIH really only funds follow-on work for things that are already known. In order to win a grant you have to have already proven your thesis. It is somewhat ridiculous.
So if you want to delegate your vote, delegate it to a non-profit. Or invest in a startup in the field you care about. Anything other than giving to the NIH.
