I think we humans see a vision of what is "correct" but often that vision is very blurred and we also like "traditions" and basic standards and don't like to thwart from them. We are our biggest chllege when it comes to many things including animal care (ie horses since we are on the topic) and such. I have often wondered why some Farriers are so rigged in thier thinking but that is because thier masters (teachers) probably where also. There was a long yearling that I often looked after that was a little bit crooked on his left front, no big deal and past the point of correction. He wore his toe down more on one side than the other and well that's just because of the mechanical function of that particular leg/ankle that was normal because of the deviation he we born with. The horse was sound, always sound. Well the owner, by listeing to a probably well meaing farrier who didnt like it and had it "corrected". It was something that in my opion did not need correction. The horse later was showing up lame, not three legged lame but was definitely lame. He stayed lame for about a year. His training was put on hold and he was basicaly reduced to a pasture pet. Well circumstances changed and a new Farrier took over the hore's hoof care. This Farrier thought outside the box. I LOVE ppl who think outside the box. (I am one of them). He examined and allowed the diviation to be what it was and trimmed and shod the hoof to allow for more natural carriage (the owner wanted him shod in front.) The owner was at first not to happy about this because of what she had been told by the other Farrier, but she was tired of dealing with a lame horse. (She had two Vets out and had all kinds of work up done on the animal only to find nothing realy wrong except being a bit crooked.) In about 3 Farrier visits the horse was sound. She did agree to allow the horse to go shoeless for the first trimming cycle (to find the natural wear of the hoof due to the crooked ankle) and went from there. Me, myself and I believed this horse would be a good canidate for going shoeless. He had great hooves and though I expressed this thought to the owner she was a die hard "shoe em'" person. So by forcing the horse to conform to what we humans think is correct or perfect the animal suffered and was lame for a long timel. But when someone thought outside the riggid box and began to examine other possibilities and letting go of the "set" standards the animal (and other things outside of the animal kingdom) became right again.
Those that think and work outside the box achieve a great deal in the realm of knowlege and experience than those that stay within the riggid confines of the box. But that's my opinion.
Ps. Thinking outside of the confines of set standards and what humans think is correct is not a guarantee that things will work for the better but it sure broadens our perspective and knowlege.
