Sortition

Sortition draws on the principle that a randomly selected group, if large enough, will statistically mirror the broader population in demographics, attitudes, and lived experience. It contrasts with electoral democracy, which selects representatives through competitive voting, and with appointment systems based on expertise or patronage.

The practice has deep historical roots. In classical Athens (roughly the 5th and 4th centuries BCE), most magistracies and the boule (council of 500) were filled by lot from among eligible male citizens, using a device called the kleroterion. Aristotle, in the Politics, characterized selection by lot as democratic and election as oligarchic, since elections tend to favor the wealthy, well-known, or rhetorically gifted. Renaissance city-states such as Venice and Florence used hybrid lottery-election systems to fill key offices and limit factionalism.

In modern practice, sortition survives most visibly in jury selection in common-law jurisdictions. Since the late 20th century it has been revived for deliberative mini-publics: citizens' assemblies, citizens' juries, and deliberative polls. Notable examples include the British Columbia Citizens' Assembly on Electoral Reform (2004), the Irish Citizens' Assembly that informed referendums on same-sex marriage (2015) and abortion (2018), and France's Convention Citoyenne pour le Climat (2019–2020). The German-speaking community of Belgium established a permanent Bürgerrat in 2019, pairing a sortition-selected citizens' council with the elected parliament.

Advocates argue sortition reduces campaign-finance distortions, partisan polarization, and incumbency advantage, while producing more representative and deliberative decisions. Critics raise concerns about accountability (lot-selected members cannot be voted out), competence on technical matters, and the difficulty of scaling deliberation. Most contemporary proposals therefore treat sortition as a complement to elected institutions—through advisory assemblies or a second chamber—rather than a wholesale replacement. Academic interest has grown through scholars such as Bernard Manin, Hélène Landemore, and the OECD's 2020 report Innovative Citizen Participation and New Democratic Institutions.
