Horses Could Be the Blueprint For Future AI Therapy Bots

BRISTOL, England — Unlike human therapists, horses can’t be fooled by fake emotions. And this is often why they prove to be such effective “counselors” when it comes to mental health. Researchers from the University of Bristol embedded themselves in equine therapy programs and found that the secret ingredient is their 2,000-pound presence, their stubborn resistance to fake emotions, and their uncanny ability to call humans on their emotional bluffs.

Now, new research presented at the 2025 CHI Conference on Human Factors in Computing Systems suggests these four-legged truth-tellers might hold the blueprint for designing robots that could change the future of mental health treatment. Instead of building predictable, comforting robots, researchers discovered we should be creating technology that’s large, somewhat unpredictable, and capable of resistance—much like therapy horses.

Why Horses Make Such Good Therapists

Equine-assisted therapy interventions have been helping people overcome trauma, anxiety, and other mental health challenges for over 70 years. These programs pair participants with specially trained horses, teaching them to communicate entirely through body language and energy rather than words. Some programs report completion rates as high as 94%, far exceeding many traditional therapies.

The researchers chose to study a program based on Parelli Natural Horsemanship, which teaches participants to practice “calm, assertive, focused and clear communication” with horses. Participants learn to guide these powerful animals using only their internal energy and subtle body language with no physical force allowed.

Rather than simply observing therapy sessions from the sidelines, lead researcher Ellen Weir decided to become a participant herself. Over four consecutive days, she worked with five different horses while wearing an audio recording device and writing detailed reflections after each session.

This “autoethnographic” approach, making yourself the subject of your own research, allowed the team to capture insights that might be invisible to outside observers. Weir documented her internal experiences, fears, and breakthroughs in real-time, while a facilitator provided separate observations and notes.

Her findings revealed that the aspects of horse therapy that initially seem counterproductive—nervousness, difficulty reading the animal’s signals, and the horse’s resistance to unclear commands—are actually essential to the therapeutic process.

Size Matters

One of the study’s most interesting findings centers on the sheer physical presence of horses. At 2,000 pounds, these animals create what researchers describe as a “palpable sense of scale and risk” that smaller therapy animals simply can’t match.

The research suggests that feeling somewhat intimidated forces people to become more self-aware and emotionally regulated. You can’t fake confidence with a horse the way you might with a therapist or a small robotic pet.

“The facilitator prompted me to assess the horse’s body language and determine its emotional state, comparing it with my own internal emotions,” Weir wrote in her research notes. She rated both herself and the horse at a six out of ten for anxiety that day, a shared vulnerability that became the foundation for their eventual partnership.

Resistance in Therapy

Unlike traditional therapy, where the therapist maintains control, horses actively resist unclear or anxious commands, forcing participants to communicate with genuine clarity and calm. Researchers call this the “human-horse dance,” a fluid exchange where leadership roles shift between participant and animal.

During one particularly challenging session, Weir worked with Peach, a horse the facilitator described as having “evil thoughts” and exhibiting “a complete lack of impulse control.” Initially, Peach took charge of their interactions, leading Weir around the arena and completely ignoring her requests.

The facilitator emphasized the importance of consistent boundaries, saying, “he’s only going to get one attempt at that; after that, don’t let him do it.” This experience taught Weir that horses, like humans, seek validation from their leaders, but only when that leadership is earned through authenticity, not demanded through dominance.

How Horses Could Influence Robot Design

Most therapeutic robots are designed to be small, predictable, and comforting. Examples are bots like PARO, the seal-like robot used in nursing homes, or the various cat and dog-inspired companions designed to provide comfort without challenge.

But the horse study suggests we might be thinking too small and too safe. Researchers propose that therapeutic robots should be large enough to command respect, sophisticated enough to provide genuine resistance when users aren’t communicating clearly, and dynamic enough to shift between leading and following roles. Rather than simply obeying commands, these robots would mirror human emotional states and respond only to calm, authentic interaction.

Current therapeutic robots are designed to minimize user anxiety and maximize compliance. But this approach misses a crucial element: productive discomfort. Nervousness and initial failure aren’t obstacles to overcome; they’re essential parts of the therapeutic journey.

In the study, participants’ anxiety served as motivation to develop better emotional regulation skills. Horses’ resistance to unclear commands taught people to communicate with greater authenticity and precision. These challenging aspects of therapy, rather than being eliminated through design for convenience, should be thoughtfully incorporated into robotic systems.

The facilitator explained that going through uncomfortable experiences is a necessary part of the intervention. Without that discomfort, it’s difficult to recognize when or how things start to feel easier over time.

This approach could also apply to robots in educational settings, workplace training, and rehabilitation programs where building confidence and emotional regulation skills are key goals.

However, creating robots large enough to command respect while maintaining safety standards presents serious engineering hurdles. Programming authentic resistance without simply frustrating users requires sophisticated artificial intelligence that can read human emotional states with horse-like accuracy.

The Access Problem

Replicating the genuine empathy and intuition of living creatures remains at the cutting edge of what’s technologically possible. The researchers are careful to position their work not as a replacement for animal-assisted therapy, but as a way to make similar benefits more widely accessible.

Horse therapy programs cost between $393,000 and $430,000 annually to operate, with a full cost recovery rate of about $1,525 per participant. Limited availability means long waiting lists and difficult access for rural populations who might live hours away from the nearest facility.

Robotic alternatives could potentially reduce costs, eliminate animal welfare concerns, and dramatically increase accessibility while preserving core therapeutic benefits. But only if designers are willing to embrace the counterintuitive lessons horses have been teaching for decades.

Can machines ever truly replace the empathetic connection that living creatures provide? Current AI systems, no matter how sophisticated, lack the genuine emotional intelligence that allows horses to read human intentions and respond authentically.

Still, this study has its researchers rethinking what therapeutic technology should be and do. By learning from horses, researchers have identified principles that could transform not just mental health treatment, but our entire relationship with helpful machines.

Real growth happens in the space between comfort and challenge, between support and resistance. We’ve spent decades trying to make technology more human-like, but perhaps we’ve been aiming at the wrong target.
