How each model solves the same problems

Instead of “democracy versus anarchism”, compare the concrete ways collective problems get solved.

Question✕✕✕
How are decisions made?Each of eight canal communities elects a board and a trustee (síndic) who must farm his own land; the trustees sit as the Tribunal and elect a president for two years.Kings of small kingdoms (túatha) under over-kings; assemblies (óenach); customary law expounded by hereditary jurists rather than legislated.A stratified random sample of 523 voters deliberated in moderated groups and plenaries and answered questionnaires before and after; no decisions were taken.Sortition / citizens' assembly
How are conflicts resolved?Weekly public oral hearings in Valencian; no written record; the trustee of the canal concerned does not vote; penalties follow each community's ordinances.ArbitrationBrehon judges; sureties (naidm, ráth, aitire); distraint of livestock; ritual fasting against higher-ranking defendants; body-fines and honour-price compensation.ArbitrationBalanced briefing materials, trained neutral moderators and competing experts structured disagreement.
How are public goods funded?Distribution of Turia water in 138 proportional shares, canal cleaning and guards financed by member levies; cheap and trusted dispute resolution.Rules on shared grazing, co-operative ploughing, mills and fencing; obligatory hospitality; churches and monasteries; few public works.Privately funded; produced published results, media coverage and a peer-reviewed study.
How is AI used?None. Hearings are oral and decided by elected farmer-trustees; no algorithmic tools are used.None; a medieval legal order.No AI role.
What are the main risks?Loss of farmland to urban growth, an ageing farming population and dependence on river flows controlled by state water authorities.CLM-0501Status-graded and unequal protection, unfree labour, endemic raiding and dynastic war, and vulnerability to a centralising conqueror.CLM-0385Self-selection into attendance; artificial setting; analysis by the method's designers; no institutional uptake.

This illustrates differences in design; it is not a universal claim about outcomes. Each cell links to mechanisms and the claims behind them.
