The McNamara Fallacy and the Problem with Numbers in Education | chronotope: "While there is some merit to this approach in certain situations, there is a deeply hubristic arrogance in the reduction of complex human processes to statistics, an aberration which led the sociologist Daniel Yankelovitch coining the term the “McNamara fallacy”:
1. Measure whatever can be easily measured.
2. Disregard that which cannot be measured easily.
3. Presume that which cannot be measured easily is not important.
4. Presume that which cannot be measured easily does not exist.
Sadly, some of these tenets will be recognisable to many of us in education – certainly the first two are consistent with many aspects of standardised testing, inspections and graded lesson observations. "
