Metaculus is a forecasting technology platform that optimally aggregates quantitative predictions of future events. Research shows that with the right incentives and feedback, groups of people can make remarkably accurate predictions of the probability of future events. Enabling this capacity is the aim of Metaculus.

Collective intelligence is at the heart of Metaculus. Our community has written thousands of questions and created hundreds of thousands of forecasts. The aggregation of the predictions of many forecasters is more accurate than that of (almost) any individual.

In addition to forecasting performance, the caliber of community discourse is very high on Metaculus. Through discussion, we can all learn from each other.

For these reasons, we will always welcome forecasting questions, suggestions, ideas, and input from our forecasters. We care about their experience, and we want to keep making it better.
