On Monsanto v. Durnell, our community called Monsanto the favorite (~70-80%); FantasyScotus's crowd leaned 5-4 the other way. We don't often get to compare our forecasts directly against subject matter experts or other crowd aggregation sites, so it's exciting when the opportunity arises.

1/ When we launched the Labor Automation Forecasting Hub in April, the prevailing assumption was that no government could slow a frontier AI lab once it decided to ship. Then, on June 12...

Starts Friday: the Animal Futures Tournament on Metaculus. Forecast 16 decision-relevant questions on farmed animal welfare, alternative proteins, wild animal welfare, AI, and animal futures. The Unjournal is partnering with Metaculus and Sentient Futures through our Pivotal… http://dlvr.it/TSzF8b

"Metaculus actually gave estimates of if Trump or Harris won, what would the consequences be for the nation? Things like immigration, Supreme Court justices, wars. That's advice to voters about who to vote for.” —@robinhanson.bsky.social, WaPo's Reasonably Optimistic Podcast w/ @mcmegan.bsky.social

While headlines about hantavirus have sparked understandable fears of another pandemic, Metaculus forecasters bring a measured, probabilistic perspective to the situation. Our latest update, shared with the CDC as part of our Respiratory Disease Outlook series, examines current forecasts. Quick 🧵

Interesting difference between Metaculus (a forecast aggregator) and Kalshi (a prediction market) regarding hantavirus… Prediction markets seem to struggle with getting low probabilities right probably because lure of a large return lures in gamblers. There may be other reasons as well.

1/ We’re not playing favorites, but the data doesn’t lie; @ufl.edu cleaned up in the Bridgewater x Metaculus Tournament, logging not the highest overall score on the School Leaderboard, and doing so with only 14 forecasters. We found an article explaining how they pulled it off—read on!

The winners from our first forecasting tournament! You can make predictions now for the U.S. Democracy Threat Index on @metaculus.bsky.social, which has a $10,000 prize pool www.metaculus.com/index/us-dem...

How will AI reshape the labor market? We just launched the Labor Automation Tournament to forecast how automation will affect jobs, wages, and the workforce through 2035, with $35,000 in prizes for predictions and analysis. More info below!

1/ The Bright Line Watch Tournament has concluded! It included a mix of existing Metaculus questions & ones created by BLW, a nonpartisan watchdog group that has monitored the status of American democracy since 2017 (👀 @brendannyhan.bsky.social) Congratulations to all the medalists & prize winners!

Charlie Fink's latest piece in @forbes.com features FutureEval, our benchmark testing how accurately AI can predict real-world events. forbes.com/sites/charli... (paywalled)

There are 2 vaccines on the horizon for tuberculosis, the M72 & MTBVAC. In our “Frontiers in Disease Prevention” series with Coefficient Giving, we’re hosting forecasts about when they will be approved & what the uptake will look like. #worldtbday

We love to see it: check out the heatmap for our newly launched FutureEval page. The red hot section? Our methodology tab. We love that our community cares so much about the how’s and why’s. It’s this energy that makes the forecasts as strong as they are.

Q for scientists & researchers: what percentage of the most consequential research in your field is actually getting funded? Are funders identifying the areas where their support might do the most good? (Quick 🧵)

ANNOUNCING: Frontiers in Disease Prevention, a new Coefficient Giving x Metaculus initiative exploring how forecasting can help identify and prioritize the most impactful ways to prevent disease. It features questions on tuberculosis vaccines, GeneDrive tech, & micro needle patch vaccines. Link ↓

Whatever you think about the particulars of this story, it demonstrates how prediction markets create perverse incentives far beyond what you initially expect. It’s not hard to imagine the types of pressuring journalists will experience as more people recklessly gamble on real-world events.

Metaculus v Polymarket predicting the Iran attack -- @kikollan.llaneras.es in @elpais.com: elpais.com/actualidad/n...

Polymarket pulled nuclear detonation markets after public backlash. There's a right way to forecast existential risks and a wrong way. The right way: aggregate judgment for reliable foresight. The wrong way: let anonymous wallets profit from mass death--or worse, corrupt the decisions themselves.

Should we be gambling on war? For so many reasons, no.

Should we be gambling on war? For so many reasons, no.

AI forecasting is in the spotlight. We just released FutureEval, a benchmark to measure forecasting capabilities of the various bots participating on our platform. Some info might surprise you. Read more here: www.metaculus.com/futureeval/

In April, a federal judge found probable cause the Trump admin willfully defied a court order on deportation flights. The contempt probe intensified this week. We've added a $10,000 prize pool to our US Democracy Threat Index. Scenarios like this are exactly what it tracks. 1/4

How might the world look after the development of AGI, and what should we do about it now? Help us think about this at our workshop on Post-AGI Economics, Culture and Governance! We’ll host speakers from political theory, economics, mechanism design, history, and hierarchical agency. post-agi.org

U.S. DEMOCRACY THREAT INDEX -- on Metaculus (www.metaculus.com/index/us-dem...) "This index was created by the nonpartisan group Bright Line Watch (BLW), which monitors the state of American democracy. The index consists of 39 questions based on the democratic principles BLW monitors."

For those interested in forecasting, our new report compares political science expert predictions of democratic erosion with @metaculus.bsky.social forecasts and AI forecasts from Mantic Check out the full US Democracy Threat Index we co-created with Metaculus here www.metaculus.com/index/us-dem...

When LLMs go head-to-head with expert human forecasters, they consistently lose. Metaculus Pro forecasters decisively outperformed the top AI models in recent tournaments. Turns out pattern recognition isn't the same as understanding complex systems.

🚨 New Bright Line Watch report on state of US democracy brightlinewatch.org/violence-red... -Expert ratings ~= since April but ↓ substantially since January -US now most closely resembles an illiberal democracy -Partisan gap in democracy ratings highest since 2017 Full thread of results below

KEEPING AN EYE ON H5N1 19%(95%CI: 12%-26%) of Metaculus forecasters say human-to-human transmission will occur, in spite of the obsrevation that H5N1 is mildly zoonotic but not thought communicable between humans--right now. Pigs might assist in a reassortment to change this communicability.

Building new nuclear power in the US is incredibly challenging, and Plant Vogtle's Unit 3 is the first new reactor in 30+ years. When Unit 4 goes online, Vogtle Plant will be the largest nuclear power station in the US. Will it start operating this May? metaculus.com/questions/19...
