Moai escalation

Claim (verbatim)

Moai escalation. This joins the moai of Rapa Nui — one of archaeology's most famous statue traditions — to the logic of competitive escalation between rival groups, the same dynamics that drive arms races. If lineages competed for prestige through statue size, each generation of carving should outdo the last by visible margins, producing a rising size chronology rather than a static or random one. Escalation of this kind does not stop voluntarily; it stops where resources do — at the frontier where transport energetics, the labour, timber, and food required to move a statue, make the next increment infeasible. The conjecture therefore makes a sharp prediction: the largest unfinished statue, still lying in the quarry, should sit precisely at the feasibility boundary — larger than anything successfully moved, and beyond what the island's transport budget could deliver. Maximum size over time should climb toward that frontier, not wander.

Prediction clause (verbatim)

For each dated moai in a size chronology combined with transport energetics estimates, record volume or mass and carving date, and compute the energetic cost of moving it from quarry to platform; estimate the feasibility boundary from plausible labour and material budgets. Primary clause: maximum moai size must show a significant rising trend across the sequence, and the largest unfinished quarry statue must exceed the largest successfully transported statue while its computed transport cost exceeds the island's feasible budget; a flat or declining size chronology, or an unfinished giant well inside the feasible range, kills the claim. The verdict follows the primary clause.

Kill-dataset (verbatim)

size chronology plus transport energetics.

Novelty / leakage triage

already answered in the literature

Substantially published: the recent 3D quarry-mapping work at Rano Raraku explicitly attributes increasing moai size to competitive escalation among family groups, and reads the largest unfinished statue (Te Tokanga, ~21 m/~270 t, beyond known transport capability) as communities testing limits — the conjecture's core including the feasibility-boundary interpretation. The formal join of size chronology to quantified transport energetics remains the open refinement.
