How has the competition world responded to natural horsemanship principles?

The competition world's response to natural horsemanship principles has been mixed and discipline-dependent, ranging from enthusiastic adoption in some western disciplines to continued resistance in others, with the most interesting developments occurring in the gradual incorporation of natural horsemanship concepts into mainstream competition training even where practitioners do not explicitly identify with the movement. Western performance disciplines — reining, ranch horse, cutting, working cow horse — have been most directly influenced, both because the Dorrance-Hunt-Brannaman lineage originates in the same western ranch tradition that these disciplines reflect and because the emphasis on softness and lightness that natural horsemanship promotes is directly visible in and rewarded by modern western performance judging. Reining's judging criteria now explicitly value lightness and responsiveness in ways that align with natural horsemanship principles, and the training language of contemporary elite reining trainers incorporates natural horsemanship concepts that would have been less common in the competition world before the movement's influence. The English sport horse world — dressage, jumping, eventing — has been more resistant to natural horsemanship specifically while simultaneously developing parallel movements toward more horse-welfare-conscious training through different vocabulary and different cultural channels. The International Society for Equitation Science and similar organizations have attempted to bridge sport horse training and behavioral science in ways that address some of the same concerns natural horsemanship raises without using natural horsemanship's specific terminology or aesthetics. Racing has been perhaps the slowest to incorporate natural horsemanship principles, with the economic pressures and compressed timelines of the racing world making the patient, understanding-based approach of natural horsemanship difficult to implement, though individual trainers within the industry have incorporated specific natural horsemanship practices into their programs.
