Another issue with the article is use of the term “accurate feedback”. It’s conflating two ideas, accuracy of data collection and statistical variation of a system. Back to the bowling example (sorry for harping on it), unless you frequently hallucinate and see the pins fall when they did not, the results in practice are very very accurate. It’s just that they describe a complex system with an initially unknown amount of variation. It’s only through having precise measurements that you can even quantify the variation.
