Infant saliva-sharing rituals reveal universal, neurobiological roots of trust—challenging cultural taboos and corporate hygiene myths
Original framing: “Young infants see saliva sharing as a sign of a close bond, experiments suggest” — Phys.org
The study ignores Indigenous saliva-sharing rituals like the Māori *hongi* and Aymara *ch’alla*, which encode trust through embodied reciprocity. These practices demonstrate that saliva-sharing is not a 'primitive' behavior but a sophisticated social technology with spiritual and communal dimensions. By framing infant saliva-sharing as a 'discovery,' the research erases millennia of Indigenous knowledge where such behaviors are central to kinship. The omission reinforces the colonial trope that non-Western cultures lack rational social structures, when in fact they offer advanced models of trust-building.
This study’s revelation that infants use saliva-sharing to signal trust exposes a profound tension between innate human behaviors and the corporate-engineered hygiene regimes that pathologize them.
The framing obscures how colonial public health campaigns—later amplified by sanitization industries—weaponized 'germ theory' to enforce social control, particularly against Indigenous and working-class communities. Cross-cultural evidence shows that saliva-sharing is not a 'primitive' behavior but a sophisticated social technology, from the Māori *hongi* to Andean *ch’alla* ceremonies, where bodily intimacy is sacred rather than 'dirty.' The Trickster’s irony lies in how 'science' now validates what Indigenous cultures have always known: trust is embodied. To restore balance, solutions must decolonize hygiene education, hold corporations accountable for exploiting innate behaviors, and redesign urban spaces to nurture communal bonding without sacrificing health. The path forward lies in recognizing saliva-sharing not as a quirk to be studied, but as a right to be protected—from both disease and the industries that profit from fear.
