A Metrics Parable ?
I remember being told a story that I really loved. Here is the version that I was told (best as I can remember).
In the days of the Soviet Union a People’s Commissar of the Commissariat for Education was doing his duty visiting schools testing the quality of the teachers by quizzing the students. Because he was the commissar he felt it was his duty(and necessity to justify his job, and negating the need to pay the teacher a stipend, because of incompetence) to prove that the education was lacking and the students double their efforts, by asking questions of increasing difficulty until every student had failed to answer a question. This strategy had served the commissar well, until one day he visited a rural school, and to his dismay one nine year old peasant boy correctly answered all of the commissars’ questions. Finally to shut down the trouble make the commissar asked the boy his trump question: “How many hairs are there on a dog?” he asked the boy, to the amazement of the commissar and the teacher, the boy replied without hesitation “3,571,962”. “How do you know this to be the correct answer?” asked the astonished commissar, to which the boy replied “If do not believe me count them yourself!” The teacher was worried, but the Commissar Broke into hearty laughter, complemented the teacher for his skill (Awarded him his stipend) and the boy for his cleverness, and vowed that he would tell the story to his colleagues at the Commissariat when he returned to Moscow, as they would really enjoy it.
When the Commissar returned the following year for his annual visit, the teacher nervously asked him how his colleagues at Commissariat responded to the story. Disappointedly he replied, “I wanted very much to tell the story, but I couldn’t. For the life of me, I couldn’t remember how many hairs the boy had said the dog had!”
I loved this story because; it spoke to me of many of the issues prevalent in measurement programs:
- Ulterior (insincere) motives to questions
- Meaningless answers to meaningless questions
- Ridiculous precision to measures
- Evil Autocracy
- Doubt that the number could be real
- Fabrication of Numbers (I am assuming the boy didn’t actually Count!)
- Mistaking the number for the message
This story is like the Swiss Army Knife of metrics stories, use it for whatever punch line you want. However, to my chagrin, I subsequently discovered the origin of the story, and …. I loved it even more! What I had heard was a version of a story (http://www.nwlink.com/~donclark/hrd/history/gestalt.html ) used by Max Wertheimer, founder of Gestalt psychology to explain the difference between learning based Gestalt principles, i.e. based upon understanding the underlying principles of the problem, and alternatives where facts are learnt without understanding them.
I think I just had a Gestalt Metrics moment, Have you? Can we be effective in a metrics program by learning hand applying the facts without understanding, or do we need to understand the underlying principles?
