Pose Questions to the Superforecasters

Who are the Superforecasters?

Good Judgment maintains a global network of nearly 200 elite Superforecaster® professionals who collaborate to tackle clients’ forecasting questions with a track record of unparalleled accuracy.

The original Superforecasters emerged in a geopolitical forecasting competition funded by the US Intelligence Community. The competition found compelling evidence that some people are exceptionally skilled at assigning probabilities to uncertain future events. Good Judgment cofounder Philip Tetlock chronicled the Superforecasters’ performance and unique attributes in his New York Times bestseller, Superforecasting: The Art and Science of Prediction.

Engaging the Superforecasters

Good Judgment’s Superforecaster Analytics is a robust alternative data source to replace vague guesses or assumptions on what will happen in the future. Professional Superforecasters work in teams to distill information from available sources into precise probabilities—delivering the most accurate forecasts as early as possible. Armed with this information, organizations can minimize risk, capitalize on opportunities much earlier and with greater confidence, and gain an enhanced perspective on issues that matter.

How Superforecaster analytics works

Pose the right questions. Once you’ve identified the topics you want to explore, Good Judgment’s expert question team will work with you to frame your questions in a way that will deliver the most accurate and actionable answers.

Involve the Superforecasters. Your questions are released to Good Judgment’s professional Superforecasters, who collaborate on our proprietary internal forecasting platform to generate informative and accurate answers within days. They then update their forecasts whenever new data, information, or analysis justifies doing so.

Receive an aggregated forecast and analysis. Good Judgment’s proprietary algorithm generates aggregated forecasts that are updated daily and made available to you through our FutureFirst™ online dashboard alongside the historical forecast trend. We can also summarize the Superforecasters’ commentary and analysis into periodic overview reports for each of your questions.

Example questions posed to the Superforecasters

  • What will be the decadal average of annual deaths caused by floods in the world from 2041 to 2050, according to Our World in Data?
  • What will be the outcome of the next UK general election?
  • How many total cases of monkeypox will be reported in the US as of 30 September 2022?
  • When will Russia and Ukraine sign or announce an agreement to end the current conflict in Ukraine?


Pose Questions to the Crowd on Good Judgment Open

Good Judgment Open

The largest forecasting platform of its kind, Good Judgment Open is Good Judgment’s crowd forecasting site. There, more than 100,000 users provide their estimates about the likelihood of future events via topical Challenges.

Good Judgment Open participants hone their forecasting skills, engage with other forecasters, and track their individual accuracy compared to that of the crowd. Top performers, evaluated on accuracy, quality, and other factors, have the chance to qualify to join the ranks of Good Judgment’s professional Superforecasters.

How it works

You can engage the public crowd and pose your own forecasting questions individually—or as a set within a Challenge with its own branded landing page. Good Judgment’s question team will help you construct the questions that best align with your goals. Once the questions are launched, a dashboard allows you to track the forecasting activity, and you can access the data any time.

Example questions posed to the crowd

  • What will be the difference in the Earth’s decadal average global surface temperature in 2091 to 2100 as compared to 1881 to 1890?
  • Will climate change be a cause of human extinction by 2300?
  • Will federal legislation providing for the establishment of a US interagency committee on global catastrophic risk become law before 1 January 2023?
  • Will doctors attempt an organ xenotransplantation (organ transplant from a nonhuman animal to a human) on a live human patient in the European Union before 1 January 2024?

Today, the commercial successor Good Judgment Inc is a forecasting consulting firm that provides public and private organizations early insights on real-world events. Our team of specially trained Superforecasters use proven principles to assign probabilities to possible outcomes—with topics ranging from geopolitics and economics to public health, finance, and technology.
