So I spent this whole week looking up the horsenality stuff. And now I am not baffled or against it. Pat himself says that some horses are all over the map in different categories and in different environments. I've managed to put 75% of horse in their accurate category and thought back to the training. I think this is meant mainly for people who do not know how to read a horse well or are not experienced. So kudos for Parelli for coming up with a chart that may help some people(less experienced) with their horses. I did read some good training tips for introverts. I tend to dislike training introverts but some of the training tips for them make sense.
I think we on this forum forget that some people aren't as horse smart or experienced as we are. I know some trainers that know how to ride but have no clue about horse personalities. I am amazed by the number of people who've ridden for years that don't do natural horsemanship yet can't even lunge their horse or roundpen it properly. So I think Parelli(and other popular trainers)are helpful with groundwork and horse sense. Because it's not all about riding. It's about horsemanship on the ground too.
