Fighting and boxing have long been central to Irish Traveller and working-class cultures, where success brings respect, bridges divides, and offers economic opportunity. As sport has embraced science—from biomechanics and conditioning to sport psychology—boxing has adopted these methods. However, cultural values such as individualism and stoicism, particularly prominent in Irish Travellers, may clash with how sport psychologists and performance (integrated) support teams manage and address performance, motivation, and anxiety. This opinion piece explores that tension through Weber’s concept of rationalisation, highlighting how some groups resist dominant norms. We argue that framing Western sport psychology as superior imposes external values and risks overlooking the unique strengths of these communities—such as resilience, self-reliance, and entrepreneurial spirit—which are deeply embedded in their approaches to combat sports and personal success. Because of this, we contend that coaches and support teams working with boxers from Irish Traveller heritage should embrace and adopt these strengths, and in so doing adopt an ethical approach that enphasises a duty of care to participants that appreciates their culture.
