I was doing a little spring house cleaning and came across a few old articles from the time when I ran a karate dojo. This was from 1994 until 2007. These articles appeared on the dojo website or in our dojo newsletter. I thought a few of them were fairly interesting, so I will share them here. This first one deals with Pareto’s Rule and Karate. An old student of mine, Lynn Hodges, wrote this article.
Pareto’s Rule and Karate
One of my older students, Lynn Hodges, after a night of working on the basic techniques of our system and the development of Chinkuchi in the techniques, went home and could not sleep until he had written these thoughts down to get them off his mind. This article is the result of that mind purge.
Ramblings and Reasoning on Pareto’s Rule and Karate
by Lynn Hodges
In many business and non-business situations, the Pareto Principle, also known as the 80-20 Rule, emerges as a statistical constant. Dr. Arthur Hafner* provides a succinct overview of Pareto’s work:
Vilfredo Pareto (1848-1923) was an Italian economist who, in 1906, observed that twenty percent of the Italian people owned eighty percent of their country’s accumulated wealth. Over time and through application in a variety of environments, this analytic has come to be called Pareto’s Principle, the 80-20 Rule, and the “Vital Few and Trivial Many Rule.”
Called by whatever name, this mix of 80%-20% reminds us that the relationship between input and output is not balanced. In a management context, this rule of thumb is a useful heuristic that applies when there is a question of effectiveness versus diminishing returns on effort, expense, or time.
Sensei Sherman Harrill often said “There’s not much I can’t handle with a good mid-block and reverse punch!” This suggests that the 80-20 rule might be at play in Isshin-ryu Karate. 80% of situations can be handled by 20% of our techniques. The key is figuring out what 20% are those ‘vital few.’ While the remaining 80% of our techniques would never be called trivial by any serious karateka, most would agree that there are techniques that rate as the most effective or at least the most fundamental in our empty hand arsenal. In conflict, we’d choose these vital 20% of our techniques about 80% of the time.
What are the vital few? That is the key question for karateka, and especially the Sensei. Logically, the basic physical moves must be part of that 20% since they underpin all of the techniques. These would include the sweeping step, the stances, the launching of the punch with hips rotating, the “opposite reaction” force, the Isshin-ryu fist and the fundamental bio-mechanics of balance, leverage and movement. Since the basics of Isshin-ryu karate also include punches, blocks and kicks, those are likely in the 20% and are described by the upper and lower charts. Therefore, it could be argued that the basic physical moves and the upper and lower charts make up the vital 20%.
Mastery of the vital 20% does two things. First, it allows us to handle 80% of the conflicts where we rely on karate for self defense. Secondly, it stages us with a firm foundation to engage the remaining 80% of the empty hand and weapons techniques that comprise our martial art style. Perhaps that is why the old masters insisted on learning the vital 20% first. One recalls stories of a single stance being the single lesson for a whole year!
Unfortunately, since the basics and charts are fundamental and seldom spectacular, a beginning karateka is anxious to rush through them, and get into the ‘real karate’ seen as the kata or sparring and competition. Reflection on the importance of these vital 20% will bring the serious karateka back to them for betterment and mastery. As one masters the basics and engages the remaining 80%, a lifetime cycle of continuous improvement begins. What we observe as “Improvement in the vital 20% results in considerable improvement in the remaining 80%!” It’s Pareto’s Rule at work in the dojo
How is that for a scientific look at the built-in efficiency of karate techniques?
While most often talked about in the business world, Pareto’s Rule applies to many other aspects of our lives. This 80-20 rule seems to very accurately reflect the effort, performance, and efficiency of many human endeavors. Think about it! Where can you see Pareto’s 80-20 rule in effect in your life?
Read other great posts here! I like to blog on a variety of topics and I do try to avoid politic. This is not a political blog. So, I do apologize if it sometimes sneaks in.
Also, please be sure to check out my military action thriller, Serpents Underfoot, and my collection of Adirondack Bear Tales! Both are receiving great reviews and both are available in both Kindle and paperback formats! I would love to hear what you think about these two books.
