Justice for All

A Judicial System for the Internet Era

What is the background image?

The background image is a Ekklesiasterion (ἐκκλησιαστήριον), the auditorium where the Greek Assembly met.

Ancient Greeks knew that corruption posed a serious threat to their judicial system. To minimize such risk, juries were made of tens or hundreds of people randomly chosen shortly before the trial. A judge or a small court could be bribed. It’s harder to bribe a crowd. But how can a large jury deliberate and issue a verdict? How can someone who is not an expert in forensic techniques evaluate complex evidence?

Athenian jury system relied on reputation. Jurors defined their vote by following their trusted experts. The shape of the ekklesiasterion was optimized for each citizen to see all the others and quickly find their trusted expert. This is how the Athenian judicial system enjoyed the advantages of a reputation system and low corruption.

CrowdJury is based on similar principles, adapted to the digital age.

Crowdjury is based on principles of collective intelligence known to the Ancient Greek.

Juries were formed by tens or hundreds of people chosen shortly before the trial. A small jury could be bribed or intimidated. But it was harder to bribe or intimidate a large crowd. Jurors were selected with a randomization device called kleroterion (Κληρωτήριον), a stone block with a series of slots arranged in rows where every citizen introduced his personal identification card (called pinakia).

The Greek Assembly met in a building called ekklesiasterion (ἐκκλησιαστήριον). The architectural shape of the ekklesiasterion was optimized for each juror to see all the others and quickly find their trusted expert in each subject. This was critical for each individual citizen to decide their vote.

Through the use of collective intelligence, Athens had fast, inexpensive and transparent trials.

Crowdjury is based on similar principles, adapted to the digital age. An algorithm optimizes a number of variables that determine the composition of the jury and the kind of evidence needed to arrive at an accurate and fast verdict at the minimal cost.
