I don’t know the paper, but this sounds like Goodhart’s Law - when you try to optimize a system by optimizing for a proxy for the outcome you want, the proxy measurement will stop being a good proxy because the system will be optimized around the proxy instead of whatever you actually wanted.
Hmm I think it was a more fundamental result than just an eponymous law. It sounded like they proved it mathematically applied to anything. Was hoping one of the HN crowd might know the actual research that was mentioned.
