People like to think of businesses as rational. Financial ratios have meaning. But businesses are evidently very susceptible to pseudoscience. They seldom hold management practices to the same standards as finance. So you get bunk like Myers-Briggs tests and Agile "velocity," which, unlike real velocity that needs units over time, is unitless and inconsistent "story points" over time. It isn't harmless. It is sand in the gears. Especially when human mismeasures and biases need to be kept out of ML systems, baking bunk into systems results in lasting damage.
