We'll be joined by journalist and bestselling author David Shenk, to discuss his new book, The Genius in All of Us: Why Everything You've Been Told About Genetics, Talent, and IQ Is Wrong. We'll dig into the relationship between intelligence, talent and genetics. When it comes to the brain, does DNA always equal destiny, or can hard work mean more than heredity? On Speaking Up we talk to Steve Thoms of Skeptic North on Homeopathy Awareness Week.
