The series that looks at current events through the lens of psychology. Michael Blastland explores the quirky ways in which we humans think, behave and make decisions. In this episode, that morning-after feeling - the aftermath of the EU referendum. We put our 'X' in a box and, one way or the other, committed. What happened in that moment and what are the consequences? Are we different now? Do we have doubts or regrets, or will we stubbornly stick to our decision? The Zoo team investigate the curious psychology of being consistent and how we make ourselves feel better about the decisions we make in life. Michael Blastland is joined by resident Zoo psychologist Nick Chater, Professor of Behavioural Science at Warwick Business School, and roving reporter Timandra Harkness. Contributors this week include Professor Ralph Hertwig, Max Planck Institute for Human Development, Berlin; Professor Greg Maio, Cardiff University; Carol Tavris, social psychologist and author; Lee Jones, Queen Mary University of London and Lois Pryce, travel writer and journalist.
