There's a fantastic video online somewhere of a martial arts instructor that had built a practice out of some form of "energetic combat", where he would run around and wave his arms, and his students -- somehow convinced that it worked -- would helpfully fall over. Then one day there was a challenge from a more traditional martial practitioner. The sensei was quite surprised when his unconvinced opponent did not fall down like he was supposed to. And even more surprised when he got smacked in the face. Unfortunately, rather than grapple with the realization that he had been practicing nonsense for years, IIRC he came up with some woo-woo excuse for why it didn't work that day, or on that opponent.
