Kinda of a stupid thought, but I'll through it out there.
What if we have a nationwide vote every year to decide what catagory gets funding for science?
x% goes to funding Biology.
x% goes to physic's.
x% goes to astronomy.
x% goes to socialigy.
Then which ever system you vote for, you pick which sub catagory gets funding, based on the overall catagories funding.
say Biology gets 40%, 50% might go toward drug research, and 50% to new surgery techniques
