Master Class

How can we better predict the future? Cognitive scientists know that forecasting is the essence of intelligence, so improving our forecasting skills will help us to become smarter, individually and collectively.

In 4 short animated videos, this masterclass will introduce you to the wisdom of crowds: a group’s ability to be smarter than the smartest person in the group, especially when it comes to making accurate predictions. You will also learn how to improve your own forecasting skills with the ABC’s of champion forecasters.

Crowd Wisdom Principles

Script Emile Servan-Schreiber

Animation & Voice Camille Larmanou

When properly organized, a crowd can be smarter than even its smartest member.

We’ll take a closer look at the discovery of the “wisdom of crowds”, dissect the “diversity theorem”, and give you the recipe for collective intelligence.

Everyone can be right, even when each person is wrong.
Larger crowds are smarter.
Diversity and expertise are interchangeable and complementary.
Collective intelligence = diversity + independence + aggregation.

Crowd Forecasting Super Power

Script Emile Servan-Schreiber

Animation & Voice Camille Larmanou

Collective intelligence pushes the limits of forecasting. Especially when too many variables are involved for a single expert to handle, or when there is too little data to feed an artificial intelligence.

How do we know this? Before and during the Covid-19 pandemic, Hypermind teamed up with the Johns Hopkins Center for Health Security in a large-scale research study aiming to test the epidemiological forecasting skills of several hundred public health experts and other medical professionals.

The results were astonishing!

An individual expert’s forecasting skills rival those of a dart throwing monkey.
But the crowd’s forecasts outperform the best forecasters in the crowd.
Reality seems to align itself with the collective forecast.

How to Think About Probabilities

Script Cara Widmer, Bandon Minnery, Emile Servan-Schreiber

Animation & Voice Camille Larmanou

The future is not written, it is probabilistic.

So let’s discuss how to think about probabilities, and how to objectively assess the accuracy of a prediction.

The only valid forecasts are those expressed as probabilities.
A forecast is never simply right or wrong.
Use the Brier score to measure the accuracy of a forecast.

ABC's of Great Forecasting

Script Cara Widmer, Bandon Minnery, Emile Servan-Schreiber

Animation & Voice Camille Larmanou

Forecasting is a matter of skill, not luck. Discover the ABC’s of how champion forecasters think, recently validated by US intelligence agencies.

Attitude: the best forecasters love contradictory points of view, stay humble, and change their minds when the facts change.
Balance: champions approach a problem by combining a macro “outside” view, using base rates, with a micro “inside” view that considers particularities.
Break it down: a complex forecast should be divided into a set of simpler and more measurable elements.
Commitment: Forecast often, and in small updates. Don’t overreact to the news.
