“Technique-based training is concrete. "He throws a straight punch and you outside block, side step and throw an inside knife-hand strike. Go do a thousand reps." It's easy to teach. He does X, you do Y. Reps. But I can think of zero actual fighters who find this valuable (except as a business model). To deal with chaos you need to train with chaos. And train is the wrong word. You need to play. Partially because play is the way animals naturally learn, partially because, in a complex system working rote drills hampers more than helps. Principles-based training involves understanding the principles and applying them in chaos. It's much harder to teach, because knowledge isn't enough, the instructor must have understanding. It's less measurable, less "objective" but infinitely more useful under stress.” - Rory Miller, Chiron Training, Concretes and Abstracts
Comments: Not till recent studies did I ever consider the obstacles created by the technique-based training model. It was one of those, “What you don’t know you don’t know” type things. It is one of those concepts that may not be implemented in programs teaching commercial self-defense, mostly or at least for many. The few who do are unique and professional while the others are commercialized and common. It means taking a complex and converting it into a simplistic so you achiever realistic goals.
