The author Max Dickins was preparing to propose to his girlfriend when he came to a realisation: he didn’t have anyone he felt he could ask to be his best man. It prompted him to write the book ‘Billy No-Mates’, looking at why he didn’t have any close male friends any more, and asking if men, in general, have a friendship problem. In a special discussion in front of a live audience at the Cheltenham Science Festival in England, Claudia Hammond speaks to Max about his journey. They’re also joined by Robin Dunbar, a Professor of Evolutionary Psychology at Oxford University who’s spent decades researching friendships in humans and other primates, and Radha Modgil, a practicing GP and wellbeing expert whose book ‘Know Your Own Power’ looks at what advice there is for people facing difficulties as they go through life. The panel look at what psychology can teach us about friendships between men, the difference these relationships can make to our mental health, and the best way of both maintaining the friendships we have and finding ways to make new friends.
