Why do men rule the world?

Listener Paula from Kenya is a computer scientist, she can’t help but notice the inequality in her workplace. With only 1 in 10 countries having female heads of state, there is no doubt that men are in charge. Paula wants to know if there is any scientific underpinning to this inequality? Perhaps it can be explained by our brains and bodies? Or does evolution weigh in? Or maybe it is all down to society and the way we raise our boys and girls. The toys and ideals we give our children must surely have an impact. And most importantly, if we want a world run by men and women equally, how can we get there? We hear how Iceland became the most gender equal country in the world. Presented by Marnie Chesterton. Produced by Caroline Steel for the BBC World Service[Image: Men in board room.
