"Superforecasters" have shown an uncanny knack for accurately predicting major events, including the course of the coronavirus pandemic.

Why it matters: The fact that we need to take action now to change the future course of the pandemic underscores the need for accurate predictions. Adopting the techniques of superforecasters could help us better anticipate the curves of this crisis.

How it works: Superforecasting brings together teams of individuals to collectively predict the likelihood of future events.

  • Prognosticators in the media will often hedge their predictions by using verbal terms such as "likely" or "probably." "But that creates confusion, because those words might mean something different for you or me, or from today or tomorrow," says Warren Hatch, the CEO of the superforecasting company Good Judgement.
  • Superforecasters use probabilities, which provide precision and accountability.
  • That accountability extends to superforecasters' willingness to revise their predictions as new data flows in, and to keep a rigorous record of those revisions.

"Too often experts make one-and-done forecasts," says Hatch, who adds this puts them at a disadvantage in a new and fast-changing situation like the pandemic.

By the numbers: As of Aug. 11, some of the superforecasting communities' predictions include...

Of note: Superforecasters accurately predicted early on that MLB would hold its first game between June 1 and July 31 (it was July 23), and that Disney World would reopen between July 1 and September 30 (it was July 11).

The bottom line: We depend on experts who often have a vested interest in their predictions. Superforecasting offers an empirically grounded alternative at a moment when the future feels more uncertain than ever.

New York Gov. Andrew Cuomo (D) said Thursday that the state will move forward with its own review process of coronavirus vaccines even if the Food and Drug Administration approves one or more for distribution and public use.

Why it matters: The motion could sow further public doubt that the federal government could release a vaccine based on political motives rather than safety and efficacy.

People in their 20s accounted for more than 20% of all COVID-19 cases between June and August, analysis from the Centers for Disease Control and Prevention shows, bringing the median age of coronavirus patients to 37, down from 46 in the spring.

Why it matters: Young people are less vulnerable to serious illness, but they contributed to community spread over the summer, the analysis says — meaning they likely infected older, higher-risk people, especially in the South.
