DESCRIPTION:Isabelle Brocas (University of Southern California)\, “Decisive
  but Rigid: How Tsimane Children Build Consensus in Networks”\, IAST Gener
 al Seminar\, Toulouse: IAST\, June 30\, 2026\, 11:30–12:30\, room Auditori
 um 4 (First floor- TSE Building).\n\nWe compare how 126 Tsimane children (
 ages 6–13) from the Bolivian Amazon and 150 children from a Los Angeles sc
 hool (LILA\, ages 5–8) solve a networked consensus task\, in which six pla
 yers with only local information must agree on one color within 30 seconds
 . Despite being several years older\, the Tsimane converge at the level of
  LILA kindergarteners rather than their LILA age-peers — a developmental d
 isplacement that age alone cannot explain. The two populations are alike i
 n unexpected ways: the same speed of first choice\, the same endogenous se
 lf-sorting into leader\, debater\, and closer roles\, and the same average
  rate of majority-following. Where they part is flexibility. Tsimane child
 ren tend to choose once and commit\, locking onto the first mover's color 
 far more often and revising far less. This decisiveness — not confusion — 
 appears to be what limits their convergence\, placing them on the rigid si
 de of the flexibility trade-off that lets older LILA children excel. Withi
 n the Tsimane\, age and household market involvement predict coordination 
 success\, while formal schooling does not.
