Shared laughter roots reveal social regulation across humans, great apes and cultures

Historical records show that laughter has been weaponized and sanctified, from Roman satyrs mocking authority to medieval court jesters subverting power through humor. These patterns illustrate that laughter functions as a social lever, not a neutral reflex, and that its evolutionary persistence is tied to its capacity to negotiate hierarchies. The study’s temporal lens misses these deep cultural continuities.
By linking the neurobiological continuity between humans and great apes with the rich tapestry of cultural, historical, and indigenous laughter practices, we see that giggling is a social technology that mediates power, heals trauma, and sustains community.
The omission of marginalized voices and non‑Western rituals in mainstream coverage reinforces a narrow scientific narrative that privileges elite institutions. Integrating trickster insights reveals how humor can both mask and expose structural inequities, urging a re‑orientation toward inclusive, interdisciplinary research. Implementing community hubs, policy metrics, and collaborative research networks can translate this systemic understanding into tangible wellbeing outcomes, honoring both our shared evolutionary heritage and cultural diversity.
