Detailed Information

Plausi is a statistical toolkit that helps ensure the integrity of vote and election results by automatically flagging patterns that warrant a closer look. Using robust statistical methods and machine learning, it detects irregularities such as unusual voter turnout patterns or results that deviate unexpectedly from what similar municipalities would be expected to show. It systematically compares results across all voting districts, making it possible to catch anomalies that would be difficult to spot by manually reviewing individual results one by one. Plausi forms the statistical foundation of the PlausiApp, which is already used for vote result quality control in the Cantons of Zurich, St. Gallen, and Thurgau. In short, it's a proven, science-based safeguard that supports confidence in the electoral process by helping authorities catch potential errors before results are finalized.
