We train to be able to react without thinking. I've read that it takes from 3,000 to 7,000 repetitions to make a response seem "instinctive." Such learned behavior can feel like it is instinctive (i.e., non-reflective), but it can only be passed on through learning and culture, not genes. (That was Lamarck's mistake.)
I just finished listening to episode 153, and was impressed with the arguments about "chaos," "gates," and dojos. Thank you Michael!
I very much like the idea of incorporating or "training around" natural reflexive actions (e.g., the startle response), because it slows us down and messes us up when we try to train against natural reactions (a la Rob Pincus).
