I can tell you my own thoughts on it. Likely nobody else will believe it or accept it, but here goes.
Of course, on the top of it all. . not everybody can be the best. I couldn't jump like Jordan, can't throw like Rodgers, can't shoot arrows like Hill. . but I CAN jump, and I CAN throw and I CAN shoot arrows.
There are two things inherently concerning with instinctive shooting.
First is the fact that, yes, a dime at ten feet is the same size as a dime at 100 yards, but see, I can plainly see the dime at ten feet.
At thirty feet I can see it less well, At 60 feet, I can just make it out and at 100 yards I can't even see it.
So right off the bat, it is easier to aim at a small target close by than it is to aim at the same small target far away. Those with better distance sight are well ahead of the others in that game.
Second, instinctive makes the brain run the show by seeing a whole picture, a target, a landscape, maybe wind (branches blowing) etc and it causes you to hold the tool in a certain way that has either been practiced exactly, or practiced closely enough to allow some cross over to give or take for the current picture.
There is no front sight to put on the target, there is no back sight to put on the front sight to better line things up. Just your brain.. Your brain is great, but face it, at distance, no matter how good your brain is, having all the add on's makes it a lot easier to get it right.
At ten feet, unless you are shooting flies, a few minutes of angle miss, or discrepancy between shots is still OK and you will likely still hit the target. At 100 yards, that exact same miss will not hit the target. And that is presuming you could see the same target to aim at in the first place.
For most folks, having a sight can be more accurate than none, having a front and rear sight is better, yadda yadda. But many of us want to shoot instinctive and we gotta deal with the limitations we are handed.
