Are you a superforecaster? I’m not

But I know of one who is!  Philip E Tetlock, and colleague Dan Gardner, are the authors of the book ‘Superforecasting: the Art and Science of Prediction’ published by Cornerstone Digital in 2015.  A Toronto-born academic, he works at the intersection between political forecasting, social science, psychology, organisational behaviour and decision making.

He started in 1984 by organising small-scale forecasting tournaments using 284 experts in various fields; by 2003 he had decided that those with the highest media profiles often had the worst results, and concluded there was a perverse inverse relationship between fame and accuracy.

In 2011 he started the Good Judgement Project (GJP) with his psychologist wife Barbara Mellers and Don Moore, a specialist in over-confidence; they aimed at harnessing the wisdom of crowds.  The 3000 volunteers only needed an interest in current affairs and an internet connection; then each forecaster’s predictions were tracked and scored.  They picked the 60 most accurate and found that they beat the professionals by a wide margin.  Tetlock concluded that ‘it doesn’t really matter how smart you are’, as recorded in an interview in Lunch with the FT (9/10 July 2016).

They then started grouping the traits these people had, which made them super forecasters.  These, summarised by Matthew Russell of M&G (, are as follows:

The ability to aggregate information from multiple sources.

Moderately intelligent and numerate.

Curious, with an appetite for information.

Open mindedness.

A healthy amount of cynicism.

They updated their forecasts regularly.

They were unafraid the change their minds.

They were humble.

Tetlock himself says that estimating the probability of unique events is a skill that can be, and is worth, cultivating.  Just the sort of thing a professional trader is doing all the time.

Now as for the traits that help, I think there are one or two that I have to work on.  I also know who ought to be more humble!

Another (slightly off-piste) book for the STA Library, maybe?
