Are we hardwired to commit ‘deadly sins’?

Scientists are increasingly finding that behaviours once seen as
depraved often have a direct physical cause. To find out more, Ian
Sample hears from Guy Leschziner, a consultant neurologist and
sleep physician at Guy’s and St Thomas’ hospital in London. His new
book, Seven Deadly Sins: The Biology of Being Human, looks at the
neurological basis of behaviours often dismissed as evidence of bad
character or lack of willpower. Help support our independent
