You may want to incentivize discoveries by financing proven talent, but that approach ignores the fact that being successfull has an important component of luck.
There's a recent economic model [1] studying the effects of sheer luck in acquiring wealth; and it shows that the richest people end up being those who accumulate a streak of lucky breaks, independently of their talent (above a minimum).
The model predicts that the best strategy for getting talented people to deliver results is giving a small amount of funding to everyone equally. This way, you maximize the chances that someone will start a project with the right approach, AND that are least some of them will have the lucky breaks required for it to flourish.
