"...the experience of losing in a simulation actually begins to condition a risk aversion pathway in the brain to which they may turn during similar experiences in the future - they may actually stop fighting and give up as they were programmed to do in training. This is why Murray will never let a student out of the training arena without ensuring that they are the decisive winner...
Yes, there will be a certain percentage of people who never grasp the training, but your goal as a professional is to keep that percentage to a bare minimum. It is easy to design a force-on-force paint bullet scenario that makes ever trainee look like an idiot, but all that proves is that the trainers are jerks. Ken Murray calls this "masterbation" - its only purpose is to act as a form of self-gratification for the trainer. But, suppose you are a trainer and you put a warrior through a scenario where he fails, and then you put him through it again and he succeeds. First you revealed a flaw in his armor and then you taught him how to shore up that weakness. In so doing, you brought him out the other end of the exercise as a superior warrior.
If there is not sufficient time and resources to run the exercise again, then just toss him a softball, and let him knock it out of the park. Your goal is to send winners out the door."

As has been pointed out by many, any moron can design a workout that will "smoke" a trainee. It's a little harder to design a workout that makes the trainee better. The effects of repeated training to "failure" and breakdown can be deleterious. That's not to say that training should never be challenging, but as I say repeatedly success breeds success (and failure breeds failure).
