What should we be eating to live a long and healthy life? How is it that some people can eat absolutely anything and stay slim, while others on a ‘healthy’ diet get fat? Why is it that Cubans are much healthier than Americans, despite eating on average twice the amount of sugar? To unpack the truth behind the often confusing information about the food we eat, Intelligence Squared brought together some of the world’s leading experts on the science of human nutrition and health. Sugar has recently replaced saturated fat as the nutritional enemy number one. The theory is that it messes with our metabolism and causes heart disease, obesity and diabetes. Arguing that sugar is the tobacco of the new millennium in our event was acclaimed science writer Gary Taubes, whose new book The Case Against Sugar has been making waves on both sides of the Atlantic. No one doubts that consuming a lot of sugar is unhealthy, but does the ‘sugar is poison’ theory really tell the whole story? A different explanation lies in a subject that has been getting a lot of attention recently – our gut microbiome. This is made up of the trillions of bacteria that inhabit our intestines and help digest our food and keep us healthy. The bad news is that the diversity of our microbes has plummeted in recent years due to the narrower range of foods and the predominance of processed junk in the Western diet. Research indicates that, rather than any single foodstuff being to blame for the rise of obesity and other modern diseases, the root of the problem lies in our depleted microbiomes. Setting out the new research on our gut bacteria and debunking many popular myths about diet was Tim Spector, an award-winning scientist who runs the British Gut project. What makes the subject even more fascinating is that we all have a very individual cocktail of bacteria in our gut, and research shows that the way we respond to food relates more to our own specific set of microbes than the calories in the food itself. Joining us was Eran Segal, one of world’s leading scientists in this field, who will explain how his lab can wire you up and predict precisely which carbohydrates you should and shouldn’t eat so as to prevent weight gain and be healthy. The results can be surprising. In 60% of cases, they show that you can enjoy sugary ice-cream but should avoid rice. A sharp critic of many of the ‘fashionable’ theories about diet and wellbeing is Sarah Jarvis, a GP who appears regularly on BBC radio and television. Her goal is to help her patients and the general public get the best quality information on nutrition and lifestyle so that they can make the informed decisions they need to be in control of their health. Chairing the event was Xand van Tulleken, a medical doctor and popular television broadcaster, who with his twin brother Chris, has presented a number of documentaries, often testing various diets on their identical genes.Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

Steven Pinker is one of the world’s leading authorities on language, mind and human nature. A professor of psychology at Harvard, he is the bestselling author of eight books and regularly appears in lists of the world’s top 100 thinkers. In 2014 he returned to the Intelligence Squared stage to discuss his latest publication 'The Sense of Style', a short and entertaining writing guide for the 21st century. Pinker argued that bad writing can’t be blamed on the internet, or on “the kids today”. Good writing has always been hard: a performance requiring pretence, empathy, and a drive for coherence. He answered questions such as: how can we overcome the “curse of knowledge”, the difficulty in imagining what it’s like not to know something we do? And how can we distinguish the myths and superstitions about language from helpful rules that enhance clarity and grace? Pinker showed how everyone can improve their mastery of writing and their appreciation of the art. Professor Pinker was in conversation with Ian McEwan, one of Britain’s most acclaimed novelists, who has frequently explored the common ground between art and science.This event took place on the 25th September 2014 at the Royal Geographical Society in London. The original producer was Executive Producer Hannah Kaye, with editing by Executive Producer Rowan Slaney and Daisy Moll.

He has been called ‘the most influential columnist in America’, and is read by everyone from small-business owners to President Obama. As a star columnist of The New York Times, Thomas Friedman has won the Pulitzer Prize three times. Although he has been dubbed ‘the high priest of globalisation’, Friedman is well aware that it is the tensions created by globalisation which have paved the way for the election of Donald Trump. Nevertheless, when he comes to the Intelligence Squared stage, Friedman will argue that contrary to Trump’s promises of walls and tariffs, it is openness to trade and ideas that will allow us all to thrive amid the rapid, startling changes sweeping through the world. Given the dizzying whirlwind of technological change which has wiped out jobs and transformed workplaces, it is no wonder that electorates have reached for Trump’s protectionist solutions in the US and nativist retrenchment in the UK. But, as Friedman will argue, the forces of globalisation needn't spell disaster. Instead, it is how we respond to these accelerating changes that will determine whether we falter or flourish. Both the EU referendum and the US presidential election were contests not between left and right, but between what Friedman calls ‘Wall People’ — those who feel their identity threatened by globalisation — and ‘Web People’: those who instinctively embrace the current pace of change and are keen to collaborate in a world without walls. In this major event, Friedman will offer his guide to updating our lives and institutions for the accelerating changes of the 21st century. For example: We need to innovate not just technologically, but politically: moral leadership in a complex world is becoming ever more essential Political leaders should be accelerating local start-ups in both the economic sector and the social sector, to build resilient and prospering citizens The ideal skill set for the jobs of the future is ‘stempathy’: science, technology, maths — and empathy Join us on January 24th, and hear how the new asset class is not information but ‘human capital talent’, and how we can all thrive in the age of acceleration.Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

Are you an optimist or a pessimist? And why should it matter? After what for many of us has been an annus horribilis in 2016, pessimists seem to have all the best tunes. Terror attacks, horror headlines from Syria, a tide of hatred and resentment poisoning our politics: the world looks increasingly grim. But what about the actual facts? If you step back and examine the data, it’s clear that life is better today for the majority of people than at any previous time in history. And we’re not just talking about the developing world, where progress has been remarkable. Here in the West, most of us have never had it so good. Just look at the improvements in health and longevity, the breadth of entertainment available, and the opportunities to travel that we blithely take for granted. In this special Intelligence Squared event, we examined two fundamentally opposing worldviews. In the optimists’ corner were Matt Ridley, author of the prize-winning The Rational Optimist, and Johan Norberg, whose latest book is Progress: Ten Reasons to Look Forward to the Future. They argued that the progress that has been made over the past centuries – whether in education, child labour, poverty or violent deaths – is now running at an unprecedented pace and that there is every reason to think that it will continue for decades to come. But is their essentially rationalist approach one that can really explain what appears to be the conflict-ridden world we live in? After all, many of us have never felt so gloomy and perplexed. This tension is not new. It has run through mainstream political thought since the Enlightenment. It set rationalists such as Adam Smith and J. S. Mill against those who sought to interpret the darker side of human nature such as Rousseau and Dostoevsky. They have been joined more recently by behavioural economists such as Daniel Kahneman and Richard Thaler. For these latter thinkers, rationalism will always fail to give a full account of human behaviour. Exploring this line of thought in our event was the acclaimed political scientist David Runciman. And steering the discussion was be the BBC’s star political editor Laura Kuenssberg. Optimist or pessimist? Some say that pessimism is dangerous, as it’s the emotions of fear and nostalgia that are fertile breeding grounds for populist demagogues. Others argue that too optimistic a view can blind us to the real threats facing our freedoms and democracy.Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

In 2011, we welcomed world renowned American cognitive scientist Steven Pinker to the Intelligence Squared stage. He argued that, contrary to popular belief, we are living in the least violent period of history, and that even the horrific carnage of the last century, compared to primitive societies, is part of this trend. Pinker claimed that, thanks to the spread of government, literacy and trade, we are actually becoming better people. He was in conversation with Matt Ridley, One of the UK’s most popular science writers, whose books - including the award-winning 'The Rational Optimist' - have sold over a million copies and been translated into 30 languages.Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

Is it a myth that women can have it all, all of the time? Or do the rising numbers of female executives in Hong Kong and around the world suggest otherwise? Does the glass ceiling exist as a barrier to the boardroom, or is the only limitation to a woman’s professional success her personal ambition? To celebrate International Women’s Day this year, Intelligence Squared Asia brought together four experts to ask whether a good mother has time to be a good CEO. In this debate, which took place in Hong Kong on 3 March 2014, award-winning journalist and author Allison Pearson and author of “Wonder Women: Sex, Power, and the Quest for Perfection” Debora Spar proposed the motion. CEO of Newton Investment Helena Morrissey and CEO of SOHO Property Zhang Xin opposed the motion.Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

It happens to all of us every day. You get rejected. Your customer doesn’t buy. Your boss doesn’t agree. Your crush doesn’t say yes. In this provocative and entertaining talk, exclusive to Intelligence Squared, American author Daniel H. Pink harvested a rich trove of social science to explain the theory and practice of bouncing back. He showed why questioning your abilities is often more effective than affirming them; why being positive (but not too positive) can improve your performance; and how to explain failure in ways that prepare you for your next encounter. Dan Pink is the author of the New York Times and BusinessWeek bestsellers A Whole New Mind and Drive. His 18-minute lecture on the science of motivation is one of the twenty most-viewed TED Talks of all time.

Have the forces of tidiness marched too far? Would we all benefit from being a bit messy? That’s the big question that the FT’s star economist Tim Harford will be asking in this exclusive Intelligence Squared event. In Harford’s view, we need to be tidy up to a point. But in some areas of life, too much order makes things rigid, fragile and sterile. Take the office, where research shows that people are more productive and creative if they are allowed to surround themselves with a bit of clutter. Or take Donald Trump. There’s no shortage of accounts that explain how this brash reality TV star, who began his campaign for the Republican nomination as a 150/1 no-hoper, ended up as President-elect of the United States. But Harford has his own theory. Trump’s rivals were tidy-minded career politicians, surrounded by lumbering professional messaging operations. Trump deployed a strategy of chaos and improvisation, confounding his enemies with his late-night tweets and moving on before they had even had time to...Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.

It’s one month since we woke up to the shock news that the next president of the United States will be Donald Trump, and the whole world is trying to read the runes and work out what the next four years will hold for America and the rest of the world. Many are decrying Trump’s election as the end of democracy and the beginning of fascism. Others, observing that he is already watering down many of his more extreme threats, are willing to see a silver lining in at least some of his avowed policies. To weigh up these conflicting attitudes and gauge what a Trump presidency might actually look like, Intelligence Squared are bringing together a high-profile cast of Republicans, Democrats, historians and former political advisers. Given what we know of Trump’s character (he’s been described by clinical psychologists as a case-book narcissist), perhaps the most pressing question is how much power he will actually be able to wield in office. To what extent will he be able to take executive action to push through...Support this show http://supporter.acast.com/intelligencesquared.See acast.com/privacy for privacy and opt-out information.
