Is there a better way to heal political divides - through panels of ordinary citizens? Sonia Sodha asks if the idea of citizens' assemblies, which have been used around the world to come up with solutions to polarising issues. Proponents argue that they avoid the risks of knee-jerk legislation, winner-takes-all outcomes or the pull of populism. Many in the Republic of Ireland believe that deliberative democracy was crucial in reforming the law on abortion without causing major political upheavals. Could this method still come up with a better way forward for Brexit?

Voters and politicians in Britain claim to be perplexed that economic and political relations between the UK and the Republic of Ireland seem to be decisive in determining the course of Brexit. They shouldn't be, argues Edward Stourton. A glance at the history of the countries' relations since the Acts of Union in 1800 helps to explain the situation.

Does a falling currency help or harm the economy? It's an urgent question for the UK, as the pound fell sharply in value against other major currencies after the referendum on Britain’s membership of the European Union in June 2016. Market commentators put this down to foreign investors becoming intensely gloomy about the prospects for the UK economy after Brexit. Others have welcomed the drop, saying it will benefit British exporters. But is it really such a simple, binary question? Paul Johnson, director of the Institute for Fiscal Studies investigates.

Are we living in a ‘golden age’ of political conspiracy theories and what does belief in them tell us about voters and politicians? James Tilley, a professor of politics at the University of Oxford, talks to historians, psychologists and political scientists to ask why conspiracy theories are so common and who are the people spreading them. Why are so many of us drawn to the notion of shadowy forces controlling political events? And are conspiracy theories, in which things always happen for a reason and where good is always pitted against evil, simply an exaggerated version of our everyday political thinking?

Does being born to non-married parents affect a child's prospects? It is a question that is notoriously hard to answer. BBC Education Editor Branwen Jeffreys investigates research from Princeton's landmark Fragile Families study, which has gathered data from 5,000 births over the last 18 years. She speaks to principal investigator Professor Sara McLanahan to find out how much we know about the differing outcomes of children raised by married, cohabiting or single parents.

Branwen asks how applicable the results of the study are to British society, where very soon, a minority of births will be to married parents. Professor Emla Fitzsimons has been following the lives of 19,000 children, born across the UK in 2000-01. She reveals what the project, know as The Millennium Cohort Study has found.

We live in a world where everyone is trying to manipulate everyone else, where social media has opened up the floodgates for a mayhem of influence. And the one thing all the new propagandists have in common is the idea that to really get to someone you have to not just spin or nudge or persuade them, but transform the way they think about the world, the language and concepts they have to make sense of things.

Peter Pomerantsev, author of an acclaimed book on the media in Putin's Russia, examines where this strategy began, how it is being exploited, the people caught in the middle, and the researchers trying to combat it. Because it is no longer just at the ‘fringes’ where this is happening – it is now a part of mainstream political life.

From a US president who is turning the world upside down – with a relish for dismantling global agreements – the message is clear: it’s America first. But where does that leave old European allies? Few expect the transatlantic relationship to go back to where it was before Trump. Europe, says Angela Merkel, now has to shape its own destiny. James Naughtie explores the uncertain future for America's friends. Producer: Kate Collins

Republican insider Ron Christie discovers how Donald Trump's presidency is changing his party. Trump arrived in the White House offering a populist revolt in America, promising to drain what he calls "the swamp that is Washington D.C". So what does his own Republican Party - traditionally a bastion of the nation’s establishment - really make of him? Where is he taking them and what will he leave behind? Christie, a long-time Republican who has served in the West Wing under George W Bush, takes us on a journey behind the scenes to meet Trump’s inner circle - including figures like Mercedes Schlapp, White House director of strategic communications, and to influential conservative broadcaster Sean Hannity. He talks to the supporters and the sceptics alike who watch in amazement as one of the most controversial presidents of all time takes his country and his party by storm.

What could cause a future financial crash? Ian Goldin, professor of globalisation and development at Oxford University, talks to some of the world's leading economists about whether we have learnt lessons from the 2008 financial crash and whether countries are now better prepared to meet the next crisis. Or are we condemned to another economic meltdown, perhaps even more severe, which would provide new fuel to the fires of populism? A decade ago, the world was taken by surprise. Will it be again? Featuring contributions from the IMF's Managing Director, Christine Lagarde, Lord Nick Stern, Professor Peter Piot, Pascal Lamy and Jeffrey Sachs.

Many key findings in psychological research are under question, as the results of some of its most well-known experiments – such as the marshmallow effect, ego depletion, stereotype threat and the Zimbardo Stanford Prison Experiment – have proved difficult or impossible to reproduce. This has affected numerous careers and led to bitter recriminations in the academic community. So can the insights of academic psychology be trusted and what are the implications for us all? Featuring contributions from John Bargh, Susan Fiske, John Ioannidis, Brian Nosek, Stephen Reicher, Diederik Stapel and Simine Vazire.
