Robin Dunbar
Anthropologist, evolutionary psychologist

Robin, currently director of the Institute of Cognitive and Evolutionary Anthropology of the University of Oxford, is renowned for creating a formula which is now known as 'Dunbar's number' - and that number is 150. This calculates the 'cognitive limit' of the number of people we can hold meaningful friendships with. When it was first formulated it created a fevered debate about the nature of and the differences between, online and real 'friendships'.
Robin will explore the psychology and ethology of romantic love to find out if the brain - and science - can help us explain how and why we fall in love.
