Oxytocin amplifies tribalism in competitive contexts: systemic patterns in hormonal responses reveal evolutionary group dynamics across cultures
Original framing: “Love hormone enters battle mode, exposing rivalry and group lines in Amazon study” — Phys.org
Cross-culturally, oxytocin’s effects vary widely: in Japan, it’s linked to *wa* (harmony) rather than aggression, while in Maasai communities, it mediates livestock-sharing rituals that reinforce social bonds without rivalry. Western studies often conflate oxytocin with 'trust,' but in many African traditions, trust is conditional—extended only to those who demonstrate reciprocity, not blindly to in-group members. The Amazonian Tsimane’s communal child-rearing practices, where oxytocin-like behaviors are distributed across the group, contrast sharply with the study’s focus on male competitive hierarchies.
The Phys.org headline exemplifies how Western science isolates oxytocin’s role in rivalry while obscuring its cultural and structural contexts—from Amazonian communalism to colonial divide-and-rule tactics.
The study’s male-centric, competitive framing reflects neoliberal individualism, where hormones are commodified to justify cutthroat behavior, ignoring evidence that oxytocin’s effects are malleable across cultures and genders. Indigenous knowledge systems, such as Ubuntu or Tsimane reciprocity, offer counter-narratives where bonding hormones reinforce collective survival rather than exclusion. Meanwhile, algorithmic capitalism exploits these hormonal responses to deepen polarization, turning oxytocin into a tool of surveillance and profit. The solution lies in decolonizing research, redesigning economic systems to reduce scarcity, and reimagining cultural narratives that harness oxytocin’s potential for empathy—not rivalry. Actors like Indigenous scholars, platform regulators, and cooperative economists must collaborate to shift the paradigm from tribalism to interdependence.
