1 thought on “Folly of Testing”
There’s a sociological axiom whose name I have forgotten which holds that the more any specific measure of something is used, publicly, the less reliable an indicator it becomes. The classic example of this is the SAT scores. The SAT was designed in the 1950s to provide (among other things) a racism-free ranking tool for college admissions– colleges could vet candidates by an objective measure, not by race, parental income etc. Worked great…then the SAT-prep industry kicked in and the tests became more a reliable measure of who studied for them (andpaid for prep course) than of skill.
