In my opinion "instinctive" is the worst possible name that could be given to a shooting method, because it implies that it is instinctive.
There's nothing instinctive about it. If there was, you wouldn't have to practice - you'd do it naturally just like you breathe and duck when something's thrown at you.
It's a learned behavior. As you practice a system of looking at what you want to hit and shooting, assuming consistent form, your brain figures out where your bow hand has to be to hit the spot you've selected. It factors in distance, what's in your peripheral vision and all the other clues it needs to get the arrow to the target and remembers them. The shots that don't get the arrow to the right point get wiped out of the memory banks, and the ones that work are kept. When you've practiced enough the whole process becomes subconscious, which is why it's mistaken for instinctive, but it's a learned behavior.
It is just like throwing a ball to hit a target, other player's glove, etc. When you first start, you're lucky to hit the ground consistently. After a while, your subconscious has it figured out so that as was said you can throw a tennis ball and a baseball and hit the same target - but that doesn't make the process instinctive - it's still learned behavior.
That's also why so many guys who are truly good shots go back and work on the bale from time to time - if your form's not consistent, you're going to make your internal computer's job impossible. It can work just fine with distance and windage, but it can't work worth a damn with form variables. To be a truly good shot you have to work on form until the variables are gone and you learn to trust your shot so your conscious mind isn't trying to mess up the shot by telling your subconscious what to do. All the subconscious needs the conscious mind to do is pick the spot to hit. Otherwise, thinking "can only hurt the ball club."
