Richard Kilgarriff shares OMI with Professor Robin Dunbar (famous for creating The "Dunbar Number" of 150 - the maximum number of relationships the human brain can maintain at any one time).
Professor Dunbar leads the social and evolutionary neuroscience research group at Oxford University and has dedicated his career to exploring and explaining the Human Social World, possibly, he says, “the most complex phenomenon in the observed universe."
His new book FRIENDS  goes deeper into the digital age to describe the power and impact of the social circles that ripple out from our most intimate relationships with family and friends to the people we just recognise in the street or on the screen.
