I haven't gone through the whole thing, but the point seems belabored and superficial tbh. I imagine the whole piece is essentially a comment on having a discriminator with great true negative rate and terrible true positive rate in a context where there is a large class imbalance (very rarely do positives occur). In real life this is quite easy to account for (just fill in your confusion matrix and see how you stand). I also strongly suspect that it doesn't really happen that much. People do have a conscience, professional pride etc. At the very least they will get bored and actually do smth different from time to time. > The Security Guard [...] The only problem is: he now provides literally no value. He’s excluded by fiat the possibility of ever being useful in any way. He could be losslessly replaced by a rock with the words “THERE ARE NO ROBBERS” on it. At the very least such a security guard would act as a human scarecrow. More realistically, the guard would actually look for robbers from time to time, if for no other reason then because if he misses them he might be out of a job. > The doctor [...] “It’s nothing, take two aspirin and call me in a week if it doesn’t improve” In my experience this sums up the Dutch (country where I currently reside) medical system quite well :)) Somehow they manage to have good health results. EDIT: moved concluding paragraph up.
