Fête de la Science - Masterclass “Wisdom of Crowds”
Wisdom of Crowds: Together We Are Stronger!
Discover the power of collective intelligence
Impulsive or sheep-like, crowds often have a bad reputation. One of the most frequent criticisms is that they encourage conformity, or even foolishness. But what if, contrary to popular belief, crowds were actually better at making good decisions than the individuals within them?
Aurélien Baillon invites us to explore the theory of the wisdom of crowds through a fun and interactive approach based on Galton’s famous experiment. The researcher will highlight the predictive power and strength of collective intelligence, as well as its wide range of applications—from politics to online betting.
Bonus challenge: take part in Galton’s test yourself by guessing the number of marbles in our jar!
