Summary
# Editorial Summary: Social Learning in Horses—Fact or Fiction? This comprehensive review examines whether horses genuinely acquire novel behaviours through observing conspecifics or whether their apparent learning relies on simpler mechanisms that don't require higher cognitive processing. Through systematic analysis of existing research, Rørvang and colleagues distinguish between social *transmission* (social facilitation, local enhancement, and stimulus enhancement—relatively simple processes requiring minimal cognitive complexity) and true social *learning* (goal emulation and imitation, which demand substantially greater neural sophistication). The authors' critical appraisal reveals that whilst horses undoubtedly respond to and are influenced by the behaviour of neighbouring horses, the current evidence does not convincingly demonstrate true social learning; instead, horses appear to rely on social facilitation and local enhancement—mechanisms well-suited to their evolutionary niche of open-landscape grazing and predator vigilance, which arguably didn't select for the metabolic expense of complex social learning abilities. This distinction carries significant practical implications: assumptions about social learning capacity have informed management decisions such as isolating stereotypical horses to prevent behavioural spread through observation, yet if such transmission operates through simpler mechanisms, these welfare-based interventions may lack scientific justification. Understanding the actual cognitive mechanisms underpinning equine social behaviour allows practitioners to base management, training, and welfare protocols on robust evidence rather than overstated mental capacities.

Practical Takeaways
- •Do not assume horses learn behavioral problems through observation of other horses—this lacks solid evidence and may lead to unnecessary isolation and management changes
- •Horses are sensitive to information transfer from conspecifics (social facilitation, local enhancement), but this is fundamentally different from true social learning and should inform behavior modification strategies
- •When addressing stereotypies or unwanted behaviors, focus on environmental and management factors rather than assuming peer-to-peer behavioral transmission
Key Findings
- •Horses demonstrate social transmission (social facilitation, local and stimulus enhancement) but lack evidence for true social learning (goal emulation, imitation)
- •Research on equine social learning may overestimate cognitive abilities, conflating simple contagious processes with genuine observational learning
- •Social facilitation and local enhancement were likely sufficient for equine evolutionary adaptation to open landscapes without requiring the neural complexity of true social learning
- •Distinguishing between social transmission and social learning is critical to avoid incorrect welfare assumptions, such as isolating stereotypical horses based on unfounded learning-by-observation concerns
