When someone makes a prediction, people post it to the site along with a brief description and a URL. We monitor it and change its status to true or false when appropriate.
They want significant, empirically testable predictions made by public figures, that have no more than a five-year horizon. Topics (thus far) are politics, technology, and finance.
Research has shown that experts make predictions at a rate worse than chance. This site exists in order to hold people and media outlets accountable for pretending to see into an unpredictable future.
And despite being often-wrong, they keep at it. And people still listen to them and cite them as authorities.
