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?Participants submitted and voted on statements in Polis; researchers kept statements with cross-group agreement and converted them into training principles.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' assemblyKings of small kingdoms (túatha) under over-kings; assemblies (óenach); customary law expounded by hereditary jurists rather than legislated.
How are conflicts resolved?Polis maps disagreement into opinion groups; statements lacking consensus across groups were excluded rather than adjudicated.Balanced briefing materials, trained neutral moderators and competing experts structured disagreement.Brehon judges; sureties (naidm, ráth, aitire); distraint of livestock; ritual fasting against higher-ranking defendants; body-fines and honour-price compensation.Arbitration
How are public goods funded?A published public constitution, methodology and evaluation results reusable by other developers and researchers.Privately funded; produced published results, media coverage and a peer-reviewed study.Rules on shared grazing, co-operative ploughing, mills and fencing; obligatory hospitality; churches and monasteries; few public works.
How is AI used?Constitutional AI: the model applies the written principles to critique its own outputs and generate training feedback.No AI role.None; a medieval legal order.
What are the main risks?Organiser discretion in translation, unrepresentative or small samples, no ongoing accountability and voluntary uptake by the developer.Self-selection into attendance; artificial setting; analysis by the method's designers; no institutional uptake.Status-graded and unequal protection, unfree labour, endemic raiding and dynastic war, and vulnerability to a centralising conqueror.CLM-0385

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