BEYOND REASONING This book tells the story of Peter Cathcart Wason, offeringunique insights into the life of the pioneering research psychologist credited for establishing a whole new field of science: the psychological study of reasoning. And this was just one of the major contributions he made to psychology. Covering much more than Wason’s academic work, the author, Ken Manktelow, paints a vivid and personal portrait of the man. The book traces Wason’s eclectic family history, steeped in Liberal politics and aristocratic antecedents, before moving through his service in the Second World War and the life-changing injuries he sustained at the end of it, and on to his abortive first attempt at a career and subsequent extraordinary success as a psychologist. Following a chronological structure with each chapter dedicated to a significant transition period in Wason’s life, Manktelow expertly weaves together personal narratives with Wason’s evolving intellectual interests and major scientific discoveries, and in doing so simultaneously traces the worlds that vanished during the twentieth century. A brilliant biography of one of the most renowned figures in cognitive psychology, this book will be of interest not only to students and scholars in thinking and reasoning, but to anyone interested in the life and lasting contribution of this celebrated scholar. Ken Manktelow was formerly Professor of Psychology at the University of Wolverhampton, having begun his academic career with a PhD on reasoning, examined by Wason himself. He is the author of several books and articles on the topic.

He left a large legacy of ideas, findings, methods and people, and some of these ideas have filtered from psychological science into public culture. His work is still being carried on. Perversely, he would struggle to survive in the academic world of the present day, even though his contribution to knowledge is immense: he is principally responsible for establishing a whole field of research, for determining what its concerns are and how they are pursued, and for the production of ideas that have influenced not just other psychologists but people more generally. This state of affairs says as much about that world as it does about him. He was a scientist of extraordinary creativity, but who needed the right environment for this creativity to thrive and work its magic. In his own time, he found it, but in the present time, he would not. He would not be allowed to. The loss would be ours as well as his. He himself attempted to write an account of his life and work centred around his most famous creation, a reasoning problem known in the business as the Wason selection task. I shall describe this task in due course, and need only note for the present that some people have claimed that it is the most widely used experimental test in the psychology of reasoning, in the psychology of thinking more generally, or in the whole of experimental psychology. It is impossible to judge these claims accurately even when looking at just the published scientific literature: there are simply too many papers, articles, books and conference proceedings to count, or to devote one’s life to counting, and there is a never- ending stream of new ones, even today.
