Are our brains hardwired to be left-wing or right-wing? How did mental health become a hot political issue? What advice can brain scientists give politicians to help get their message across? This week David interviews Professor Barbara Sahakian – the renowned neuropsychologist who has worked with the U.K. government on questions of mental health and well-being – to discover the lessons of new scientific research for our politics. The team then discuss the Labour and Conservative manifestos and the inner tensions they reveal within the parties, and what their pledges really mean in an age of coalitions and compromise. And, in the week when Hilary Clinton declared her presidential candidacy, we debate the time spans of political campaigns in the UK and the U.S., and the different ways the two countries do politics.

It is said that trust in politics is at an all-time low. Our politicians are seen as out of touch and out to fill their own pockets. But when does mistrust become something more profound? This week we discuss this phenomenon in its most extreme form: conspiracy theories. What conspiracy theories do the British public believe? How commonplace are they, and how have they spread? Are people really so wrong to believe that the world is run by a secret elite? We interview a team of Cambridge researchers for answers. Then David turns to Professor Simon Szreter - social historian and founder of ‘History & Policy’ - to discuss how academics are trying to find ways of restoring the public’s faith in politics, and bridge the gap between the politicians’ narrow view of the world and how the voters see it. The team also discuss the television debates, politicians’ use (and abuse) of facts and figures, Tony Blair, and UKIP’s strategy for electoral success. Posted 8/4/15

What makes our politics uniquely ‘British’? Why is there no English Independence Party? How did the NHS become a sacred cow? And will Britannia ever rule the waves again? David puts these questions to Professor Robert Tombs – historian and author of a new epic history of England – to discover the impact of culture and foreign affairs on British political life. The team also review David Cameron and Ed Miliband’s favourite books, the pros and cons of the fixed-term Parliament, the neglected but extraordinary Nigerian election, and what to expect between now and polling day.

Could Margaret Thatcher have won this election? How would the Iron Lady have handled UKIP? Who would win more seats in 2015 – her or David Cameron? In a special episode featuring remarkable research, we put these questions to Michael Howard, former Conservative Leader and member of Mrs Thatcher’s Cabinet, and Stephan Shakespeare, founder of the polling firm YouGov. Other insights include the untold story of how polling impacted the Westminster vote for the Iraq War, why Cameron was wrong to rule out a third-term in office, and the only thing that Michael Howard and Gordon Brown agree upon.

What constitutes hate speech? Does the Press do more harm than good in our democracy? When should words become the government’s business? We put these questions to Professor Rae Langton – award-winning philosopher and the world’s ‘fourth most influential woman thinker’ – and discuss whether free speech can ever be reconciled with a need to suppress hateful voices. The team then discuss the fallout of Ed Miliband’s ‘second kitchen’, whether politicians can – or should – keep their families out of the media spotlight, and the lessons from the Israeli election result.

Will the United Kingdom stay together? What have England’s politicians got wrong that Scotland’s have got right? Which had the greater impact on the Scottish Independence Referendum result – people’s views of the past, or of a possible future? We put these questions to the historian and documentary-presenter Clare Jackson, whose widely acclaimed BBC series on the Stuart dynasty was broadcast in the run-up to Referendum last year. The team then discuss the potential impact of Scotland in the upcoming election, and the legacy of a vote that saw the highest electoral turnout in over 60 years. Posted 11/3/15.

Could Facebook really decide the outcome of this election? Is the Internet a positive force for democracy? Why is global surveillance, as unveiled by Edward Snowden, not an electoral issue? We put these questions to Prof John Naughton – author of A Brief History of the Future and early advocate of the Internet’s power to change the world – and ask if politicians are tuned-in to the transformative potential of social media. Putting cynicism to one side, the team then give their good-points about the General Election so far. Posted 4/3/15.

David asks Martin Jacques – journalist, academic, and author of the bestseller When China Rules the World – if this election matters in global terms. Will the transformation of China overshadow short-term political events in Britain and Europe? How does China adapt in the absence of democratic elections? Is it possible for our politicians to successfully supervise Britain’s steady decline? The team also discuss the week’s political events. Posted 25/2/15.

How can we reconcile short-term politics with the long-term global problems we face? Should scientists wield more political power? Is it fair to criticise politicians for faults in our political system, or is it our failing? Or is democracy itself to blame? David puts these questions to Lord (Martin) Rees – cosmologist, Astronomer Royal, and former President of the Royal Society – and someone who believes that mankind only has a 50% chance of making it through this century without a serious global “setback”. The team then debate this week’s political events. Posted 18/2/15. For more information about this episode and others go to http://www.cam.ac.uk/podcasts/election
