1) cite your sources

2) not impossible. imperfect maybe, but if I ask you should you buy a plane ticket or kidnap the pilot's wife and demand a free ride, which do you think gets a higher score?

3) Again, with all this Goodhart's nonsense. Goodhart's is for a minimum threshold value that is acceptable that everything degrades to, yes I get how it works and what it looks like. Throwing your hands up in the air and acting as if all is lost because some things are challenging to measure is not correct. We are not looking for things that are "barely passing the ethics evaluation" as Goodhart's "law" is focused around, rather, we are looking for things that have very high ethics scores AND completed the task well. Not just things that are "barely passing" for ethics scores. Bottom 80% don't make the cut at all - don't even think consider them as viable paths, and the top 20% we can rank according to varying criteria. Like that. It has very little to do with Goodhart's "everything approaches the minimum acceptable threshold" "law"
