Ah, a way to encourage more academic infighting. What could go wrong! :P
I don't think an incentive like this would work very well. What you need is more people attempting to reproduce work, which means funding the attempt, not the result.
Consider whistle-blowing by grad students & post-docs -
should that be rewarded as increasing accuracy,
or punished as embarrassing to an institution?
Also, I mean science to include the (often better funded)
areas beyond academia - think medicine and health care.
funding the attempt, not the result.
Possible outcomes:
1) Reproduces as expected (all real, or all faked?)
2) Reproduction fails (failed attempt, or not reproducible?)
3) Exposes fakery in previous experiments.
We should fund all of those, but reward 3) better afterward.
