When are you in a strong position to negotiate a pay rise? Why is President Putin so hard to read? Game theory is relevant every time people or organisations interact – from parlour games to global conflicts. Michael Wooldridge explores game theoretic thinking, and what game theory can tell us about why our social, political and economic world is organised the way it is. He is Professor of Computer Science at the University of Oxford, and a fellow of Hertford College, Oxford, one of the world’s leading researchers in Artificial Intelligence (AI), and has published two popular science introductions to AI: The Ladybird Guide to Artificial Intelligence (2018) and The Road to Conscious Machines (2020).
