Thanks for the article. I agree with your assessment of types of training available, which can be applied to so much more than wilderness survival. Most of the training problems come from the instructor either being out to prove something, or just not being qualified.
I taught firearms and other topics in the FLETC and also have experience teaching Boy Scouts and other groups of youth and adults outdoor survival and other topics. It's a fine balance to teach so the student "gets it" and not overwhelm them with stuff, and yet teach what they need to know. It's important to focus on principles, which will apply in any situation, and then add a variety of techniques to apply those principles in different ways depending on circumstances. This teaches them what they need to know, and opens them up to experimenting with different ways to accomplish the goal without being locked in to any one method. I think this produces a much better result. It motivates them to continue to experiment and learn after the formal training is concluded.
