Radical Uncertainty Decision Making Beyond The Numbers

Much economic advice is bogus quantification, warn two leading experts in this essential book, now with a preface on COVID-19. Invented numbers offer a false sense of security; we need instead robust narratives that give us the confidence to manage uncertainty. “An elegant and careful guide to thinking about personal and social economics, especially in a time of uncertainty. The timing is impeccable." — Christine Kenneally, New York Times Book Review Some uncertainties are resolvable. The insurance industry’s actuarial tables and the gambler’s roulette wheel both yield to the tools of probability theory. Most situations in life, however, involve a deeper kind of uncertainty, a radical uncertainty for which historical data provide no useful guidance to future outcomes. Radical uncertainty concerns events whose determinants are insufficiently understood for probabilities to be known or forecasting possible. Before President Barack Obama made the fateful decision to send in the Navy Seals, his advisers offered him wildly divergent estimates of the odds that Osama bin Laden would be in the Abbottabad compound. In 2000, no one—not least Steve Jobs—knew what a smartphone was; how could anyone have predicted how many would be sold in 2020? And financial advisers who confidently provide the information required in the standard retirement planning package—what will interest rates, the cost of living, and your state of health be in 2050?—demonstrate only that their advice is worthless. The limits of certainty demonstrate the power of human judgment over artificial intelligence. In most critical decisions there can be no forecasts or probability distributions on which we might sensibly rely. Instead of inventing numbers to fill the gaps in our knowledge, we should adopt business, political, and personal strategies that will be robust to alternative futures and resilient to unpredictable events. Within the security of such a robust and resilient reference narrative, uncertainty can be embraced, because it is the source of creativity, excitement, and profit.

If you want to go in one direction, the best route may involve going in another. This is the concept of 'obliquity': paradoxical as it sounds, many goals are more likely to be achieved when pursued indirectly. The richest men and women are not the most materialistic; the happiest people are not necessarily those who focus on happiness, and the most profitable companies are not always the most profit-oriented as the recent financial crisis showed us. Whether overcoming geographical obstacles, winning decisive battles or meeting sales targets, history shows that oblique approaches are the most successful, especially in difficult terrain. John Kay applies his provocative, universal theory to everything from international business to town planning and from football to managing forest fire.

“Mervyn King may well have written the most important book to come out of the financial crisis. Agree or disagree, King’s visionary ideas deserve the attention of everyone from economics students to heads of state.” —Lawrence H. Summers Something is wrong with our banking system. We all sense that, but Mervyn King knows it firsthand; his ten years at the helm of the Bank of England, including at the height of the financial crisis, revealed profound truths about the mechanisms of our capitalist society. In The End of Alchemy he offers us an essential work about the history and future of money and banking, the keys to modern finance. The Industrial Revolution built the foundation of our modern capitalist age. Yet the flowering of technological innovations during that dynamic period relied on the widespread adoption of two much older ideas: the creation of paper money and the invention of banks that issued credit. We take these systems for granted today, yet at their core both ideas were revolutionary and almost magical. Common paper became as precious as gold, and risky long-term loans were transformed into safe short-term bank deposits. As King argues, this is financial alchemy—the creation of extraordinary financial powers that defy reality and common sense. Faith in these powers has led to huge benefits; the liquidity they create has fueled economic growth for two centuries now. However, they have also produced an unending string of economic disasters, from hyperinflations to banking collapses to the recent global recession and current stagnation. How do we reconcile the potent strengths of these ideas with their inherent weaknesses? King draws on his unique experience to present fresh interpretations of these economic forces and to point the way forward for the global economy. His bold solutions cut through current overstuffed and needlessly complex legislation to provide a clear path to durable prosperity and the end of overreliance on the alchemy of our financial ancestors.

This book describes the classical axiomatic theories of decision under uncertainty, as well as critiques thereof and alternative theories. It focuses on the meaning of probability, discussing some definitions and surveying their scope of applicability. The behavioral definition of subjective probability serves as a way to present the classical theories, culminating in Savage's theorem. The limitations of this result as a definition of probability lead to two directions - first, similar behavioral definitions of more general theories, such as non-additive probabilities and multiple priors, and second, cognitive derivations based on case-based techniques.

“There are words that are so familiar they obscure rather than illuminate the thing they mean, and ‘learning’ is such a word. It seems so ordinary, everyone does it. Actually it’s more of a black box, which Dehaene cracks open to reveal the awesome secrets within.”--The New York Times Book Review An illuminating dive into the latest science on our brain's remarkable learning abilities and the potential of the machines we program to imitate them The human brain is an extraordinary learning machine. Its ability to reprogram itself is unparalleled, and it remains the best source of inspiration for recent developments in artificial intelligence. But how do we learn? What innate biological foundations underlie our ability to acquire new information, and what principles modulate their efficiency? In How We Learn, Stanislas Dehaene finds the boundary of computer science, neurobiology, and cognitive psychology to explain how learning really works and how to make the best use of the brain’s learning algorithms in our schools and universities, as well as in everyday life and at any age.

Forecast geopolitics and markets with this clear and insightful resource Geopolitical Alpha – An Investment Framework for Predicting the Future provides readers with an original and compelling approach to forecasting the future and beating the markets while doing so. Persuasively written by author, investment strategist, and geopolitical analyst Marko Papic, the book applies a novel framework for making sense of the cacophony of geopolitical risks with the eye towards generating investment-relevant insights. Geopolitical Alpha posits that investors should ignore the media-hyped narratives, insights from "smoke-filled rooms," and most of their political consultants and, instead, focus exclusively on the measurable, material constraints facing policymakers. In the tug-of-war between policymaker preferences and their constraints, the latter always win out in the end. Papic uses a wealth of examples from the past decade to illustrate how one can use his constraint-framework to generate Geopolitical Alpha. In the process, the book discusses: What paradigm shifts will drive investment returns over the next decade Why investment and corporate professionals can no longer treat geopolitics as an exogenous risk How to ignore the media and focus on what drives market narratives that generate returns Perfect for investors, C-suite executives, and investment professionals, Geopolitical Alpha belongs on the shelf of anyone interested in the intersection of geopolitics, economics, and finance.

Two of the UK's leading economists call for an end to extreme individualism as the engine of prosperity 'provocative but thought-provoking and nuanced' Telegraph Throughout history, successful societies have created institutions which channel both competition and co-operation to achieve complex goals of general benefit. These institutions make the difference between societies that thrive and those paralyzed by discord, the difference between prosperous and poor economies. Such societies are pluralist but their pluralism is disciplined. Successful societies are also rare and fragile. We could not have built modernity without the exceptional competitive and co-operative instincts of humans, but in recent decades the balance between these instincts has become dangerously skewed: mutuality has been undermined by an extreme individualism which has weakened co-operation and polarized our politics. Collier and Kay show how a reaffirmation of the values of mutuality could refresh and restore politics, business and the environments in which people live. Politics could reverse the moves to extremism and tribalism; businesses could replace the greed that has degraded corporate culture; the communities and decaying places that are home to many could overcome despondency and again be prosperous and purposeful. As the world emerges from an unprecedented crisis we have the chance to examine society afresh and build a politics beyond individualism.
