You can tell an awful lot about a society by who it labels a genius. You can also learn from who it excludes from that category, who it enables and what it is prepared to tolerate from them. The tortured poet, the rebellious scientist, the monstrous artist, or indeed the tech disruptor.

All of these archetypes feature in The Genius Myth, the new book by the journalist, author and podcaster Helen Lewis. She joins Hugh Linehan to talk about so-called geniuses, from Elon Musk to The Beatles, the modern influence of concepts like IQ, and what it takes to be a political genius.
