Conflict is created when we make a horse do stuff that is not its idea to do. Conflict is avoided when the stuff we want our horse do is the same as the stuff they want to do.
Gadgets in Horse Training
Training horses well is a skill that is learned over a long time. It is not possible to circumvent the process by taking short cuts. The behaviour that gadgets are intended to shape is something that good horse people learn along the way to becoming good horse people. A person cannot learn to be a talent with a horse by resorting to gadgets because they undermine the process of becoming a good horse person.
