In this edition of the Podcast of Ideas, Rob Lyons talks to Alastair Donald from the Future Cities Project about what can be done to solve the UK's housing crisis and barrister Jon Holbrook comes in to tell us why he would scrap the Human Rights Act. Rob also talks to Dr Fiona McEwen from King's College London's Institute of Psychiatry on new research, which appears to show that autism is largely caused by genetic and not environmental factors, members of the Institute of Ideas team give us their opinions on the week's stories, and Geoff Kidder reports back from the inaugural session of the Dublin Salon.
