Sortition is a method of filling public roles by random lottery rather than by election or appointment. Ancient Athens ran most of its government this way, and the principle survives today most visibly in the American jury system, where federal law requires jurors to be drawn at random from a fair cross-section of the community. A smaller but growing modern use is the citizens’ assembly, in which randomly chosen residents are convened to advise governments on policy questions.
The appeal of the method is the same across more than two thousand years of use. A lottery cannot be lobbied, cannot be bought, and cannot favor the already powerful. Everyone in the pool has an equal mathematical chance of being chosen, so the resulting body tends to look like the community it is drawn from rather than like the narrow slice of people who seek office.
The Athenian Origins
Athens filled most administrative and legislative posts by random draw. The purpose was explicitly anti-oligarchic: lottery prevented wealthy or politically connected individuals from monopolizing public roles the way elections tended to let them. The core idea has not changed. If a position does not require specialized expertise, random selection from the eligible population produces a body that is harder to corrupt and more representative than one chosen by vote.
Sortition in the American Jury System
The jury is where sortition does its heaviest work in modern American life. Federal jury selection draws its authority from the Jury Selection and Service Act of 1968, codified primarily in Chapter 121 of Title 28 of the U.S. Code. The statute declares that every litigant entitled to a jury trial in federal court has the right to grand and petit juries selected at random from a fair cross-section of the community where the court sits.1Office of the Law Revision Counsel. 28 USC 1861 – Declaration of Policy It also prohibits excluding anyone from service based on race, color, religion, sex, national origin, or economic status.2Office of the Law Revision Counsel. 28 USC 1862 – Discrimination Prohibited
Each of the 94 federal district courts must maintain a written plan describing exactly how it will select jurors. These plans are reviewed by judicial councils to make sure they comply with the transparency and fairness requirements of the statute.3Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection If a court departs from its own plan, the stakes are real: indictments can be dismissed and verdicts overturned.
Building the Pool
Random selection is only as good as the pool it draws from. Federal courts start with voter registration records. When voter lists alone don’t reflect a representative slice of the community, courts must add supplemental sources such as driver’s license records or state identification databases.3Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection Some districts also pull from tax records or utility service lists. The combined lists are cleaned regularly to remove people who have died, moved away, or appear as duplicates, with courts comparing their records against National Change of Address data from the postal service. The resulting master jury wheel is the foundation of every subsequent draw.
Drawing the Names
Names are then drawn from the master wheel at random, typically using computerized random number generators designed to give every name an equal chance of selection. Courts test the algorithms to verify they don’t skew toward or against particular demographic groups or neighborhoods. A few jurisdictions still use physical lottery drums or transparent containers of numbered cards for smaller or ceremonial draws, with a neutral party or mechanical device pulling the required number of names.
Drawn names don’t go straight to a courtroom. Each person first receives a juror qualification questionnaire, which must be completed, signed, and returned within ten days.4Office of the Law Revision Counsel. 28 USC 1864 – Drawing of Names From the Master Jury Wheel The form collects the information the court needs to decide whether the person meets the statutory requirements. Those who pass this stage go into a smaller “qualified jury wheel,” and names are drawn from that second pool when a trial or grand jury needs to be assembled.
Who Is Eligible
To serve on a federal jury, a person must be a U.S. citizen, at least 18 years old, and have lived primarily in the judicial district for at least one year. They must also be able to read, write, and speak English well enough to follow courtroom proceedings and complete the questionnaire. Several conditions automatically disqualify a person: pending felony charges carrying more than a year of imprisonment, a prior felony conviction without restoration of civil rights, or a mental or physical condition that cannot be reasonably accommodated.5United States Courts. Juror Qualifications, Exemptions, and Excuses
Certain roles are exempt by statute. Active-duty military members, police officers, and firefighters cannot be compelled to serve, and neither can public officials in the executive, legislative, or judicial branches who are actively performing their duties. Volunteer emergency responders can request an excuse and must be granted one.3Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection These carve-outs narrow the pool somewhat, but they are the exception. The default is that any adult citizen in the district is eligible to be drawn.
Petit Juries and Grand Juries
Two different kinds of juries come out of this process. A petit jury is the trial jury most people picture. In federal criminal cases it must have at least six members, with twelve being the traditional number, and the jurors hear evidence, listen to arguments, and deliver a verdict that must be unanimous.6Legal Information Institute. US Constitution Annotated – Amendment VI – Size of the Jury A grand jury serves a different function. It does not decide guilt or innocence; it reviews evidence presented by prosecutors to determine whether there is probable cause to charge someone with a crime. Federal grand juries consist of 16 to 23 members, their proceedings are secret, and they hear only the prosecution’s side.7Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Both are seated through the same random-selection pipeline.
Where Randomness Stops
Sortition in the jury context has a boundary worth naming. Random selection builds the pool and populates the courtroom, but it does not seat the final jury. Once prospective jurors arrive, the judge and attorneys question them in a process called voir dire, and some are removed for cause while each side also uses a limited number of peremptory challenges to strike jurors without stating a reason.8United States Courts. Juror Selection Process The Supreme Court held in Batson v. Kentucky that using peremptory challenges to exclude jurors based on race violates the Equal Protection Clause, and the prosecutor must offer a race-neutral explanation when a pattern suggests race-based strikes.9Justia. Batson v Kentucky, 476 US 79 (1986) So the jury that actually hears a case is not purely sortitive. It is a randomly drawn pool filtered through adversarial challenges.
Sortition in Citizens’ Assemblies
Outside the courthouse, sortition is used to convene citizens’ assemblies and deliberative panels that advise governments on policy. These bodies gather a randomly chosen, demographically representative group of residents, give them access to expert testimony, and ask them to work through a complex issue over a period of days or weeks. Recent U.S. examples include a Washington State climate assembly in 2021, a citizens’ assembly in Petaluma, California on the future of a contested fairground in 2022, and a Michigan panel that evaluated COVID-19 policy responses in 2020.
Participants are typically paid a daily stipend to offset lost wages and travel costs, though compensation structures vary widely across jurisdictions and no universal standard exists. The recommendations these assemblies produce are usually non-binding, forwarded to legislatures or executives for further action. They lack the legal force of a jury verdict, but they offer something elections don’t: the considered judgment of people who weren’t seeking power and who reflect the community’s actual makeup rather than the narrow slice that runs for office.
Why Random Selection Is Used
The common thread between a federal grand jury and a municipal climate assembly is a specific theory of legitimacy. Decisions carry weight because the people making them weren’t chosen for their ambition, wealth, or political connections. They were chosen because their name came up. That mechanism is what makes the body hard to capture by any faction, and it is what makes the result look, demographically and attitudinally, like the public itself. Elections produce representatives; sortition produces a sample. Both have their place, and the modern American system uses sortition where impartiality and representativeness matter more than expertise or mandate.
