Think you have what it takes to make good predictions?  Since 2011, the Good Judgment Project (GJP) has been making predictions on issues of international relations and foreign affairs, recently winning the IARPA (Intelligence Advanced Research Projects Activity) prediction contest.  Predictions from the GJP have been startlingly accurate, outperforming prediction markets, and exceeding even optimistic expectations.  It's run by Phillip Tetlock, the famous predictor of "foxes and hedgehogs" fame.

From the Monkey Cage article:

How does the Good Judgment Project achieve such strikingly accurate results? The Project uses modern social-science methods ranging from harnessing the wisdom of crowds to prediction markets to putting together teams of forecasters. The GJP research team attributes its success to a blend of getting the right people (i.e., the “right” individual forecasters) on the bus, offering basic tutorials on inferential traps to avoid and best practices to embrace, concentrating the most talented forecasters into super teams, and constantly fine-tuning the aggregation algorithms it uses to combine individual forecasts into a collective prediction on each forecasting question. The Project’s best forecasters are typically talented and highly motivated amateurs, rather than subject matter experts.

But the good news is that you now have a chance to get involved with GJP Season 3 if you think you're a great predictor:

If you enjoy world politics and appreciate a good challenge, consider joining the Good Judgment Project, which has openings right now for Season 3 forecasters. The Project will give you the opportunity to receive training, to get regular feedback on your forecasting accuracy, and to test your forecasting skills against those of some of the most accurate forecasters around.
