classic example of Goodhart's law ("When a measure becomes a target, it ceases to be a good measure") or, if you prefer, Campbell's law ("The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.").
While most film-PR companies aim to get the attention of critics from top publications, Bunker 15 takes a more bottom-up approach, recruiting obscure, often self-published critics who are nevertheless part of the pool tracked by Rotten Tomatoes. In another break from standard practice, several critics say, Bunker 15 pays them $50 or more for each review. (These payments are not typically disclosed, and Rotten Tomatoes says it prohibits "reviewing based on a financial incentive."
The Bunker 15 employee replied that of course journalists are free to write whatever they like but that "super nice ones (and there are more critics like this than I expected)" often agreed not to publish bad reviews on their usual websites but to instead quarantine them on "a smaller blog that RT never sees. I think it's a very cool thing to do." If done right, the trick would help ensure that Rotten Tomatoes logged positive reviews but not negative ones.
