Opponents rarely go to war without thinking they can win--and clearly, one side must be wrong. This conundrum lies at the heart of the so-called "war puzzle": rational states should agree on their differences in power and thus not fight. But as Dominic Johnson argues in Overconfidence and War, states are no more rational than people, who are susceptible to exaggerated ideas of their own virtue, of their ability to control events, and of the future. By looking at this bias--called "positive illusions"--as it figures in evolutionary biology, psychology, and the politics of international conflict, this book offers compelling insights into why states wage war. Johnson traces the effects of positive illusions on four turning points in twentieth-century history: two that erupted into war (World War I and Vietnam); and two that did not (the Munich crisis and the Cuban missile crisis). Examining the two wars, he shows how positive illusions have filtered into politics, causing leaders to overestimate themselves and underestimate their adversaries--and to resort to violence to settle a conflict against unreasonable odds. In the Munich and Cuban missile crises, he shows how lessening positive illusions may allow leaders to pursue peaceful solutions. The human tendency toward overconfidence may have been favored by natural selection throughout our evolutionary history because of the advantages it conferred--heightening combat performance or improving one's ability to bluff an opponent. And yet, as this book suggests--and as the recent conflict in Iraq bears out--in the modern world the consequences of this evolutionary legacy are potentially deadly.

Overconfident: How Economic and Health Fault Lines Left the Middle East and North Africa Ill-Prepared to Face COVID This report examines the region’s economic prospects in 2021, forecasting that the recovery will be both tenuous and uneven as per capita GDP level stays below pre-pandemic levels. COVID-19 was a stress-test for the region’s public health systems, which were already overwhelmed even before the pandemic. Indeed, a decade of lackluster economic reforms left a legacy of large public sectors and high public debt that effectively crowded out investments in social services such as public health. This edition points out that the region’s health systems were not only ill-prepared for the pandemic, but suffered from over-confidence, as authorities painted an overly optimistic picture in self-assessments of health system preparedness. Going forward, governments must improve data transparency for public health and undertake reforms to remedy historical underinvestment in public health systems.

An expert on the psychology of decision making at Berkeley’s Haas School of Business helps readers calibrate their confidence, arguing that some confidence is good, but overconfidence can hinder growth. A surge of confidence can feel fantastic—offering a rush of energy, even a dazzling vision of the future. It can give us courage and bolster our determination when facing adversity. But if that self-assurance leads us to pursue impossible goals, it can waste time, money, and energy. Self-help books and motivational speakers tell us that the more confident we are, the better. But this way of thinking can lead to enormous trouble. Decades of research demonstrates that we often have an over-inflated sense of self and are rarely as good as we believe. Perfectly Confident is the first book to bring together the best psychological and economic studies to explain exactly what confidence is, when it can be helpful, and when it can be destructive in our lives. Confidence is an attitude that takes into account both personal feelings and the facts. Don Moore identifies the ways confidence behaves in real life and raises thought-provoking questions. How optimistic should you be about an uncertain future? What justifies your confidence in something amorphous and subjective like your attractiveness or sense of humor? Moore reminds us that the key to success is to avoid being both over- and under-confident. In this essential guide, he shows how to become perfectly confident—how to strive for and maintain the well-calibrated, adaptive confidence that can elevate all areas of our lives.

In literature, overconfidence has been blamed for economic bubbles and crises as well as for international conflicts and wars. While education has already been shown to impact one’s level of overconfidence previous research focused on the length and profoundness of education. This study, in contrast, examines the connection between overconfidence and the field in which a person has been educated. The issues covered are therefore how education and mind set are related, why a differentiation between “quantitative” and “qualitative” education makes sense in this context, and how different mind-sets influence an individual’s proneness to overconfidence. Drawing on the dual process concept of reasoning from psychology it is argued that the focus of one’s education may have an influence on individual levels of overconfidence through distinct ways of reasoning that are acquired and practiced during higher education. As support for this theory, data on the overconfidence of CEOs of the largest German companies is used and experiments for future research on this topic are suggested.

Mixed modelling is one of the most promising and exciting areas ofstatistical analysis, enabling more powerful interpretation of datathrough the recognition of random effects. However, many perceivemixed modelling as an intimidating and specialized technique.

'Brilliant ... it will change how you think about confidence.' Johann Hari 'Important for everyone but crucial for women.' Mary Robinson 'Interesting and important.' Steven Pinker __________ Why do boys instinctively bullshit more than girls? How do economic recessions shape a generation's confidence? Can we have too much confidence and, if so, what are the consequences? Imagine we could discover something that could make us richer, healthier, longer-living, smarter, kinder, happier, more motivated and more innovative. Ridiculous, you might say... What is this elixir? Confidence. If you have it, it can empower you to reach heights you never thought possible. But if you don't, it can have a devastating effect on your future. Confidence lies at the core of what makes things happen. Exploring the science and neuroscience behind confidence that has emerged over the last decade, clinical psychologist and neuroscientist Professor Ian Robertson tells us how confidence plays out in our minds, our brains and indeed our bodies. He explains where it comes from and how it spreads - with extraordinary economic and political consequences. And why it's not necessarily something you are born with, but something that can be learned.

This book presents a review of the role of overconfidence in small firms and explores how biased judgment and decision-making can affect business performance. Whilst the overconfidence construct has been studied in detail, there are no systematic reviews of its role in SMEs as of yet. Examining the decisions made by entrepreneurs, this study offers clear solutions on how to improve business accuracy, reduce disadvantageous investments and prevent bankruptcy. Providing an empirical analysis of overconfidence in the sport industry, this new book will not only be of interest to academics of entrepreneurship and small enterprises, but also to sport managers.

Are you endlessly trying to improve your employees' customer service skills, but getting so-so results?

These powerful, sometimes counterintuitive insights can be applied at the organizational, departmental, or individual level to help the entire team deliver outstanding customer service.Note: the first edition of this book was published under the title, Service Failure: The Real Reasons Employees Struggle with Customer Service and What You Can Do About I

Human beings are not model epistemic citizens. Our reasoning can be careless and uncritical, and our beliefs, desires, and other attitudes aren't always as they ought rationally to be. Our beliefs can be eccentric, our desires irrational and our hopes hopelessly unrealistic. Our attitudes are influenced by a wide range of non-epistemic or non-rational factors, including our character, our emotions, and powerful unconscious biases. Yet we are rarely conscious of such influences. Self-ignorance is not something to which human beings are immune. In this book Quassim Cassam develops an account of self-knowledge which tries to do justice to these and other respects in which humans aren't model epistemic citizens. He rejects rationalist and other mainstream philosophical accounts of self-knowledge on the grounds that, in more than one sense, they aren't accounts of self-knowledge for humans. Instead he defends the view that inferences from behavioural and psychological evidence are a basic source of human self-knowledge. On this account, self-knowledge is a genuine cognitive achievement and self-ignorance is almost always on the cards. As well as explaining knowledge of our own states of mind, Cassam also accounts for what he calls 'substantial' self-knowledge, including knowledge of our values, emotions, and character. He criticizes philosophical accounts of self-knowledge for neglecting substantial self-knowledge, and concludes with a discussion of the value of self-knowledge. This book tries to do for philosophy what behavioural economics tries to do for economics. Just as behavioural economics is the economics of homo sapiens, as distinct from the economics of an ideally rational and self homo economics, so Cassam argues that philosophy should focus on the human predicament rather than on the reasoning and self-knowledge of an idealized homo philosophicus.

Doctors are taught how to cure people. But they don’t always know how to care for them. Hardly anyone is happy with American healthcare these days. Patients are getting sicker and going bankrupt from medical bills. Doctors are burning out and making dangerous mistakes. Both parties blame our nation’s outdated and dysfunctional healthcare system. But that’s only part of the problem. In this important and timely book, Dr. Robert Pearl shines a light on the unseen and often toxic culture of medicine. Today’s physicians have a surprising disdain for technology, an unhealthy obsession with status, and an increasingly complicated relationship with their patients. All of this can be traced back to their earliest experiences in medical school, where doctors inherit a set of norms, beliefs, and expectations that shape almost every decision they make, with profound consequences for the rest of us. Uncaring draws an original and revealing portrait of what it’s actually like to be a doctor. It illuminates the complex and intimidating world of medicine for readers, and in the end offers a clear plan to save American healthcare.
