How does natural horsemanship address a spooky horse?

Natural horsemanship addresses spookiness as a training and confidence-building project rather than as a character defect to be managed or suppressed, recognizing that a horse spooks because its threat-detection system is responding appropriately to what it perceives as genuine danger rather than because it is being difficult. The foundational approach is systematic desensitization — progressive exposure to the specific stimuli that trigger spooking at levels the horse can experience without crossing its flight threshold, repeated until the horse's response to those stimuli decreases from reactive flight to curious investigation or genuine indifference. The specific techniques for desensitization vary between traditions — Clinton Anderson's sacking out procedures, Parelli's Friendly Game, Monty Roberts's join-up-based confidence building — but all share the principle of working below the threshold rather than flooding the horse with stimulus above its ability to process. Beyond specific desensitization work, natural horsemanship addresses spookiness by developing the horse's overall emotional fitness and its trust in the trainer as a reliable source of leadership in uncertain situations. A horse that trusts its trainer deeply and has learned to look to the trainer for guidance about how to assess uncertain situations will be significantly less spooky than the same horse without that relationship, because the trainer's calm in the face of the concerning stimulus provides a reference point that the horse can use to recalibrate its own assessment. Warwick Schiller's work on emotional fitness offers the most recent and most comprehensive framework for addressing chronic spookiness that does not respond to conventional desensitization — his approach addresses the underlying nervous system dysregulation that makes some horses chronically reactive rather than focusing only on habituating the horse to specific stimuli.
