The superforecasters
How to predict the future and beat the wisdom of the crowds. Manuela Saragosa speaks to Warren Hatch, chief executive of Good Judgement, a consultancy that specialises in superforecasters - individuals with a knack for predicting future events - and the techniques they use to make their guesses. We also hear from Andreas Katsouris from PredictIt, a political betting platform that harnesses the wisdom of the crowds in making predictions about politics.
