Metaculus is a reputation-based site for soliciting and aggregating predictions. It was founded in November 2015 by astrophysicist Anthony Aguirre, cosmologist Greg Laughlin and data scientist Max Wainwright.[1][2]
Tutorials
The official Metaculus tutorials[3] are suitable for beginners as a way to introduce forecasting, probability distributions, and a basic understanding of how to behave under uncertainty.
Tutorial #1 is over-explaining for those with a basic understanding of the forecasting, but still a good introduction to using Metaculus specifically.
For those familiar with forecasting, tutorials #2 and #3 are more useful as a (small) amount of calibration practice and building familiarity with the Metaculus interface.
A video introduction to Metaculus is also available[4].
Funding
As of August 2022, Metaculus has received $5.6 million in grants from Open Philanthropy,[5] and over $300,000 from Effective Altruism Funds.[6]

I added FLI as a related entry. This is because Anthony Aguirre co-founded both orgs. But the orgs have fairly distinct missions and activities, and I don’t think there’s any other connection apart from through Aguirre, so maybe that isn’t worth mentioning the Related entries.
Yeah, I think the connection is not strong enough to justify inclusion, so I removed it. I don’t have strong views on this, though, so feel free to revert my edit if you (Michael or anyone else) think it’s definitely worth including.
