The soul of one horse offers one path to the top. The teacher will come when the student is ready. In the wild, all it's learning is influenced by the herd strucure and dynamic. You probably deal with individual horses as well, even if you handle several horses in the course of a day, since you are probably dealing with each horse one at a time. The horses are, for you, isolated units, not members of a group.
People judge other people the same way.
No wonder horses have so many problems. We make them that way. Spend at least one hour just watching. Do not talk to your horse or in any way influence its behavior. If at all possible, watch your horse interact with other horses.
