Wow. Really creepy. In some ways, I want to blame cop culture, but I have to also admit that a huge chunk of this story has to be about what happens when you reward and punish based on metrics, especially metrics involving a computer. People do some bad crazy shit when a computer has some numbers that say thumbs up thumbs down -- especially when a little fudging can change those numbers and thus, those thumbs.
I used to say it was important to make sure you were measuring the right thing, that measuring the wrong thing was worse than useless. More and more, however, I am questioning whether measurement is ever a good idea. That desirable certainty is a little too desirable, and all too often, also fraudulent.
