A clip from Stephen Bartlett’s podcast has resurfaced and gone viral for claiming that a group of men will go extinct because women don’t want to date and have children with them anymore. It’s prompted questions about whether society should intervene to help men find a date and what women are attracted to in a male partner. Professor of Psychology at Durham University, Linda Boothroyd, speaks to Adam Fleming about the science of attraction and how women’s expectations of men have changed over time.
