Using prediction polling to harness collective intelligence for disease forecasting.

ABSTRACT:

Background

The global spread of COVID-19 has shown that reliable forecasting of public health related outcomes is important but lacking.

Methods

We report the results of the first large-scale, long-term experiment in crowd-forecasting of infectious-disease outbreaks, where a total of 562 volunteer participants competed over 15 months to make forecasts on 61 questions with a total of 217 possible answers regarding 19 diseases.

Results

Conclusions

Crowd forecasting efforts in public health may be a useful addition to traditional disease surveillance, mo
