A Behavioral Scientist Notable Book of 2021 A Next Big Idea Club Best Nonfiction of 2021 From the New York Times best-selling author and host of Hidden Brain comes a thought-provoking look at the role of self-deception in human flourishing. Self-deception does terrible harm to us, to our communities, and to the planet. But if it is so bad for us, why is it ubiquitous? In Useful Delusions, Shankar Vedantam and Bill Mesler argue that, paradoxically, self-deception can also play a vital role in our success and well-being. The lies we tell ourselves sustain our daily interactions with friends, lovers, and coworkers. They can explain why some people live longer than others, why some couples remain in love and others don’t, why some nations hold together while others splinter. Filled with powerful personal stories and drawing on new insights in psychology, neuroscience, and philosophy, Useful Delusions offers a fascinating tour of what it really means to be human.

Sex discrimination is supposedly a distant memory. Yet popular books, magazines and even scientific articles defend inequalities by citing immutable biological differences between the male and female brain. Why are there so few women in science and engineering, so few men in the laundry room? Well, they say, it's our brains.

Psychologists, psychotherapists, psychiatrists and nurses are increasingly involved in treatments which include psychological therapy, and particularly cognitive therapy, for serious mental disorders. The aim of this book is to guide such professionals towards better practice by treating the individual symptoms of delusions, voices and paranoia, rather than by the categorisation of schizophrenia. The authors provide an introduction to their cognitive model and show how therapy depends crucially on the collaborative relationship with the client. While earlier approaches to these distressing symptoms depended on an overall model of schizophrenia which emphasised fundamental discontinuities with normal thought and psychological processes, the authors? approach is supported by substantial research that indicates that delusions, voices and paranoia lie on a continuum of differences in thought and behaviour, and do not arise from fundamentally different psychological processes. This book offers a practical, research-based and essentially hopeful approach to the assessment and treatment of psychotic disorders and also an argument for the development of a person model for treatment, which is based on the person?s enduring psychological vulnerabilities.

This “disturbing yet fascinating” exploration of mass mania through the ages explains the biological and psychological roots of irrationality (Kirkus Reviews). From time immemorial, contagious narratives have spread through susceptible groups—with enormous, often disastrous, consequences. Inspired by Charles Mackay’s nineteenth-century classic Memoirs of Extraordinary Popular Delusions and the Madness of Crowds, neurologist and author William Bernstein examines mass delusion through the lens of current scientific research in The Delusions of Crowds. Bernstein tells the stories of dramatic religious and financial mania in western society over the last five hundred years—from the Anabaptist Madness of the 1530s to the dangerous End-Times beliefs that pervade today’s polarized America; and from the South Sea Bubble to the Enron scandal and dot com bubbles. Through Bernstein’s supple prose, the participants are as colorful as their “desire to improve one’s well-being in this life or the next.” Bernstein’s chronicles reveal the huge cost and alarming implications of mass mania. He observes that if we can absorb the history and biology of this all-too-human phenomenon, we can recognize it more readily in our own time, and avoid its frequently dire impact.

The authors offer cogent reviews of the literature pertaining to the formation and maintenance of delusions, but the most substantial parts of the monograph expound the empirical inquiries which they and their colleagues have carried out in recent years. Most of the research has been published elsewhere, but such is the relevance of the experiments cited to the whole schema that the monograph has unique value. It is a synthesis which portrays the contribution to date of cognitive science to the biology and psychopathology of delusional thinking, and convincingly demonstrates that this way of looking at things has a considerable future. There are important implications for therapy as well as for hypothesis formulation. The monograph is attractively written, and the authors present their claims with exemplary modesty. The whole tenor of their approach gives weight to the conviction that here we have a story that must be taken seriously. It is a significant book, and I warmly commend it to all those with an interest in the future of psychopathology, and especially to psychiatrists who wish to advance their understanding of mental states and avoid stagnating with outworn dogma." - Robert Cawley, University of London in British Journal of Psychiatry Delusions are a key symptom of psychosis and yet there is no single book which considers delusions from a psychological perspective. In part this is because the syndrome of schizophrenia has captured the attention of many workers, and in part because delusions, as private mental phenomena, are not well suited to purely behavioural or observational methods of enquiry. For the past two decades, however, cognitive psychology has been in its ascendancy and delusions, as beliefs, are particularly amenable to investigation applying cognitive concepts and methods. Within this framework, it is possible to consider continuities between delusional and ordinary beliefs, as well as to seek to identify differences. This book, therefore, uniquely presents a psychological model of delusions, employing the neglected strategy of single symptom research and the tools of cognitive psychology

What sort of mental state is a delusion? What causes delusions? Why are delusions pathological? This book examines these questions, which are normally considered separately, in a much-needed exploration of an important and fascinating topic, Kengo Miyazono assesses the philosophical, psychological and psychiatric literature on delusions to argue that delusions are malfunctioning beliefs. Delusions belong to the same category as beliefs but - unlike healthy irrational beliefs - fail to play the function of beliefs. Delusions and Beliefs: A Philosophical Inquiry will be of great interest to students of philosophy of mind and psychology and philosophy of mental disorder, as well as those in related fields such as mental health and psychiatry.
