Warning: Potential Severance spoilers ahead.
I finished watching Severance S1, and one of the open questions is what work the innies are actually doing. And reading this article it strikes me that the Severance work is the ideal culmination of the worker tracking + Goodhart's law cycle.
You make # of clicks a metric, so then the best performers are those who optimize for # of clicks, and so an AI trying to improve work efficiency by emulating what the best performers are doing rewards nonsensical clicking over actual work, and that cycle continues until you end up with something like the Severance job, which involves nothing but click and dragging numbers into 1 of a few bins based on how you "feel" about the numbers. At the same time the innies are told that what they are doing is extremely important.
YOu have the perfect combination of mindless work, which is not entirely monotonous (because you have to go by your "feeling", which would not be the case if you just had to repeatedly drag 1 number to the same bin) and at the same time you're motivated because you're convinced you're participating in a great good. This way you maximize the measured busywork output while still preventing your employees from immediately burning out.
