Not everyone tells the truth. ‘Read my lips: no new taxes.’ ‘This isn’t going to hurt.’ ‘I see no ships, my lord.’ ‘Of course I love you.’ When can we know what to believe? Four out of five of us don’t think politicians tell the truth, according to a recent MORI poll. But is telling the truth always the right or best thing to do? If it isn’t, what happens to trust? If it is, are there different kinds of truth? Do we always want to hear the truth? Do different professions need to have systemically different attitudes to truth-telling? Is there a moral difference between outright lies, falsehoods, deceits, dissimulation and just plain old ‘economy with the actualité’? In October 1013, Intelligence Squared headed to London's Westminster Abbey to discuss truth with a politician (Jack Straw), a journalist (Max Hastings), a scientist (Professor Robert Winston) and a poet (Wendy Cope). — We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be.  Send us an email or voice note with your thoughts to podcasts@intelligencesquared.com or Tweet us @intelligence2.  And if you’d like to support our mission to foster honest debate and compelling conversations, as well as ad-free podcasts, exclusive bonus content, early access and much more, become a supporter of Intelligence Squared..
