Seems easy to solve. Just make it harder to get money for studies. Evaluate the applications for funding using stricter criteria or something. I'm not even saying that less money be used for them. The ones that pass muster should be given the extra money. It's a win/win because the most money would be going to the most worthwhile studies then. There have to be cases where someone comes up with an awesome, useful, but expensive study, and can't be funded because the people in charge of the funding did too many "Is cocaine really addictive" and "Is sleeping on your head bad for your neck" studies that year.
