We've upgraded Metaculus's binary question groups to make forecasting faster and more efficient. Each question is equipped with its own slider, which means fewer steps to make your forecasts.
Try the new interface on one of these question groups:
This feature is temporarily hidden while we address a bug with the sliders. I’ll update once it’s live again.
All right, the feature is back up!
Metaculus is conducting its first user survey in nearly three years. If you have read analyses, consumed forecasts, or made predictions on Metaculus, we want to hear from you! Your feedback helps us better meet the needs of the forecasting community and is incredibly important to us.
Take the short survey here — we truly appreciate it! (We'll be sure to share what we learn.)
Where do you disagree with other forecasters? Which community predictions have shifted the most? And what was that nanotech forecast you meant to update? Metaculus has introduced new filter & sort tools that provide more control over the forecast feed so you can find the questions that matter to you.Learn more
I love this!
Sort of an aside but it would be really lovely if we could build a database with every prediction on Metaculus and also tons of estimates from other sources (academia, etc) so that people could do squiggle-type estimations that source all the constants.
🔬 Metaculus Officially Launches APIMetaculus has officially launched the Metaculus API, providing access to a rich, quantitative database of aggregate forecasts on 7000+ questions. Start exploring, analyzing, and building here.
