Operant words, there. Because you've never seen a horse ask, "Can't we just go straight/go into the trailer/whatever, doesn't mean it's never happened. It has worked time & again. I've seen reverse psychology work time & again with horses. Untold numbers have gotten their horses over loading issues using reverse psychology as I described.
We can't go into paralysis of analysis/theorizing over what'll work. Horses don't care about our theories. We can't even go into logic for our answers to horsemanship. Horses don't operate via our logic, necessarily.
A couple more examples of reverse psychology that've worked with many horses:
When a horse wants to get nibbly/pushy with his mouth on you, say, ok, & rub his muzzle just a bit harder than is enjoyable for him, so he'll say, "Can't we just do something else?"
When a horse wants to go right-brain (scared of everything & wants to run away) the human says, ok, & helps the horse to run around, till horse says, "Can't I just relax?"
These & more examples of reverse psychology are in PP program & are endorsed by PP. Hope that helps!
then why does parelli put such an emphasis on the theory of his program? i did the theory, presented linda's theory in a way that compromised pats theory, proving that linda's parelli's horsemanship program compromises pat parelli's horsemanship program.
if a horse bites, "rubbing his muzzle harder" isn't what linda suggests. she might not even know this, but her theory indicates that if a horse bites we should solve that by sticking our fingers inbetween its teeth and wiggling them around.
"thats ridiculous!" says the linda afficiandos, but if you actually studied the theories behind her methods you'd find this to be true.
what you called "direct opposition" is pats method, direct opposition with pressure that comes on slowly and releases quickly. thats how we get horses to "ask us questions"
pat says this, in one of his newwest riding dvds he is in the arena on magic and says that when approaching a corner with a turn or a stop in the corner as the options, you should wait untill the very very very last moment to choose an option, and if the horse picks an option before you, do the opposite. he words it slightly differently "if you feel the horse bank to turn, stop in the corner and if you feel the horse going for a stop in the corner, bank to turn"
the horse will establish a pattern of asking a question when approaching a corner. if the horse banks to turn left and you turn it sharply to the left, it will establish a pattern of the horse banking even harder to turn left in anticipation of the hard left turn.
