About Metaculus

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.

What makes us different?

  • We are a reputation-based online community of experienced forecasters and new learners.
  • Metaculus brings together a highly engaged network of thousands of forecasters.
  • Our proprietary aggregation engine is the basis of our established forecasting track record, which has been publicly available since 2015.
  • Unlike traditional prediction markets, incentives and scoring rules on the Metaculus platform are aligned for accuracy in the long-term.

How does Metaculus generate accurate forecasts?

The human mind is an incredible engine for forecasting. But the world is complex, and many predictions are hard to make. Science has developed largely to fill this gap, making stunning predictions about systems that can be accurately modeled mathematically or numerically using theoretical constructs, but there are times when it still cannot predict the behavior of complex systems.

It is often assumed that events within such systems are simply unpredictable. But they aren’t. Of all the numerical ranges that Metaculus has forecast, 94% were more accurate than random guessing. You can see the Metaculus track record across all questions since 2015.

How do I start forecasting?

You can dive into the questions right away to start exploring, but if you want to make predictions and track your score we encourage you to sign upsign up for a Metaculus account. We have tutorials that will help you get a handle on the basics and hone your forecasting skills, and if you're ever confused about how things work you can find many answers in the FAQ. You can see your personal track record on your profile page to keep track of how you improve over time. Happy predicting!

How does Metaculus work?

Metaculus poses questions about the occurrence of a variety of future events, on many timescales, to our growing community of participating forecasters. Like many mental capabilities, prediction is a talent that persists over time and is a skill that can be developed. By giving steady quantitative feedback and assessment, forecasters can improve their skill and accuracy, as well as develop a quantified track record. Then, probabilities of future events can be reliably drawn by optimally aggregating predictions — counting more heavily those with domain expertise and a strong track record.

Some events — such as eclipse timing and well-polled elections, can often be predicted with high resolution, e.g. 99.9% likely or 3% likely. Others — such as the flip of a coin or a close horse-race — cannot be accurately predicted; but their odds still can be. Metaculus aims at both: to provide a central generation and aggregation clearinghouse for predictions. With these in hand, we believe that individuals, groups, corporations, governments, and humanity as a whole will make better decisions.

As well as being worthwhile, Metaculus aims to be interesting and fun, while allowing participants to hone their prediction prowess and amass a track-record to prove it.
