was used to select eligible and willing citizens to serve jury duty. This bolstered the initial
Athenian system of democracy by getting new and different jury members from each tribe to avoid corruption. James Wycliffe Headlam explains that the Athenian Council (500 administrators randomly selected), would commit occasional mistakes such as levying taxes that were too high. Headlam found minor instances of corruption but deemed systematic oppression and organized fraud as impossible due to widely (and randomly) distributed power combined with checks-and-balances. Furthermore, power did not tend to go to those who sought it. The Athenians used an intricate machine, a

Lombardy and Venice – 12th to 18th century
The ''brevia'' was used in the city states of Lombardy during the 12th and 13th centuries and in Venice until the late 18th century.
Men, who were chosen randomly, swore an oath that they were not acting under bribes, and then they elected members of the council. Voter and candidate eligibility probably included property owners, councilors, guild members, and perhaps, at times, artisans. The Doge of Venice was determined through a complex process of nomination, voting and sortition.
Lot was used in the
Venetian system only in order to select members of the committees that served to nominate candidates for the Great Council. A combination of election and lot was used in this multi-stage process. Lot was not used alone to select magistrates, unlike in Florence and Athens. The use of lot to select nominators made it more difficult for political sects to exert power, and discouraged campaigning.
By reducing intrigue and power moves within the Great Council, lot maintained cohesiveness among the Venetian nobility, contributing to the stability of this republic. Top magistracies generally still remained in the control of elite families.
Florence – 14th and 15th century
''Scrutiny'' was used in
Florence
Florence ( ; ) is the capital city of the Italy, Italian region of Tuscany. It is also the most populated city in Tuscany, with 362,353 inhabitants, and 989,460 in Metropolitan City of Florence, its metropolitan province as of 2025.

for over a century starting in 1328.
Nominations and voting together created a pool of candidates from different sectors of the city. The names of these men were deposited into a sack, and a lottery draw determined who would get to be a magistrate. The scrutiny was gradually opened up to minor guilds, reaching the greatest level of Renaissance citizen participation in 1378–1382.
In Florence, lot was used to select magistrates and members of the Signoria during republican periods. Florence utilized a combination of lot and scrutiny by the people, set forth by the ordinances of 1328.
In 1494, Florence founded a Great Council in the model of

[Edmund Burke (1790), ''Reflections on the Revolution in France'']
Bernard Manin, a French political theorist, was astonished to find so little consideration of sortition in the early years of representative government. He wonders if perhaps the choosing of rulers by lot may have been viewed as impractical on such a large scale as the modern state, or if elections were thought to give greater political consent than sortition.
However,
David Van Reybrouck disagrees with Manin's theories on the lack of consideration of sortition. He suggests that the relatively limited knowledge about

played a major role, with the first thorough examination coming only in 1891 with ''Election by Lot at Athens.'' He also argues that wealthy enlightenment figures preferred to retain more power by holding elections, with most not even offering excuses on the basis of practicality but plainly saying they preferred to retain significant elite power, citing commentators of 18th century France and the United States suggesting that they simply dislodged a hereditary aristocracy to replace it with an elected aristocracy.
Switzerland
Because financial gain could be achieved through the position of mayor, some parts of Switzerland used random selection during the years between 1640 and 1837 to prevent corruption.
Methods

Before the random selection can be done, the pool of candidates must be defined. Systems vary as to whether they allot from eligible volunteers, from those screened by education, experience, or a passing grade on a test, or screened by election by those selected by a previous round of random selection, or from the membership or population at large. A multi-stage process in which random selection is alternated with other screening methods can be used, as in the Venetian system.

) utilizes a variety of perspectives and cognitive skills to find better solutions. According to numerous scholars such as Page and Landemore,
this diversity is more important to creating successful ideas than the average ability level of a group. Page argues that random selection of persons of average intelligence perform better than a collection of the best individual problem solvers.
This "diversity trumps ability theorem" is central to the arguments for sortition.

critiques representative democracy as requiring citizens to vote for a large package of policies and preferences bundled together in one representative or party, much of which a voter might not want. He argues that this does not translate voter preferences as well as sortition, where a group of people have the time and the ability to focus on a single issue. By allowing decision-makers to focus on positive-sum endeavors rather than zero-sum elections, it could help to lessen

Some studies show an overrepresentation of psychopathic and narcissistic traits in elected officials, which can be solved through sortition by not selecting for people who seek power.
Participation
Burnheim also notes the importance of legitimacy for the effectiveness of the practice. Legitimacy does depend on the success in achieving representativeness, which if not met, could limit the use cases of sortition to serving as consultative or political agenda-setting bodies. Oliver Dowlen points to the

nature of all citizens having an equal chance of entering office irrespective of any bias in society that appear in representative bodies that can make them more representative. To bolster legitimacy, other sortition bodies have been used and proposed to set the rules to improve accountability without the need for elections. The introduction of a variable percentage of randomly selected independent legislators in a Parliament can increase the global efficiency of a legislature, in terms of both number of laws passed and average social welfare obtained (this work is consistent with a 2010 paper on how the adoption of random strategies can improve the efficiency of hierarchical organizations).
As participants grow in competence by contributing to deliberation, they also become more engaged and interested in civic affairs. Most societies have some type of citizenship education, but sortition-based committees allow ordinary people to develop their own democratic capacities through direct participation.
Modern application
Sortition is most commonly used to form

drawing straws). In public decision-making, individuals are often determined by allotment if other forms of selection such as

Sortition is also used in military conscription, as one method of awarding US green cards, and in placing students into some schools, university classes, and university residences.
Within organizations
Sortition also has potential for helping large associations to govern themselves democratically without the use of elections. Co-ops, employee-owned businesses, housing associations, Internet platforms, student governments, and other large membership organizations whose members generally do not know many other members yet seek to run their organization democratically often find elections problematic. Examples include the Samaritan Ministries Health Plan using a panel of 13 randomly selected members to resolve select disputes and the New Zealand Health Research council awarding funding at random to applicants considered equally qualified.

Each group would consist of perhaps a thousand citizens randomly selected, and would either set an agenda of issues or deal with a particular major issue. It would hold hearings, commission research, and engage in debate and discussion. Dahl suggests having the minipopuli as supplementing, rather than replacing, legislative bodies. Claudia Chwalisz has also advocated for using citizens' assemblies selected by sortition to inform policymaking on an ongoing basis.

Michael Donovan proposes that the percentage of voters who do not turnout have their representatives chosen by sortition. For example, with 60% voter turnout a number of legislators are randomly chosen to make up 40% of the overall parliament. A number of proposals for an entire legislative body to be chosen by sortition have been made for the United States, Canada, the United Kingdom, Denmark, and France.
Étienne Chouard advocates strongly that those seeking power (elected officials) should not write the rules, making sortition the best choice for creating constitutions and other rules around the allocation of power within a democracy. He and others propose replacing elections with bodies that use sortition to decide on key issues.

Simon Threlkeld proposed a wide range of public officials be chosen by randomly sampled juries, rather than by politicians or popular election.
