In a surprising new trend, young men and women around the world are dividing by gender on their politics and ideologies. Whilst young women are becoming more liberal, young men are becoming more conservative. Tim Harford speaks to John Burn-Murdoch, Columnist and Chief Data Reporter at the Financial Times, about why this global phenomena may be occurring and Dr Heejung Chung, Professor of Sociology at the University of Kent, explains why the ideological divisions between young men and women in South Korea are some of the most extreme.
