In two minds: Dual processes and beyond

Abstract This book explores the idea that we have two minds – one being automatic, unconscious, and fast, the other controlled, conscious, and slow. In recent years, there has been great interest in so-called dual-process theories of reasoning and rationality. According to such theories, there are two distinct systems underlying human reasoning: an evolutionarily old system that is associative, automatic, unconscious, parallel, and fast; and a more recent, distinctively human system which is rule-based, controlled, conscious, serial, and slow. Within the former, processes are held to be innate and to use heuristics that evolved to solve specific adaptive problems. In the latter, processes are taken to be learned, flexible, and responsive to rational norms. Despite the attention these theories are attracting, there is still poor communication between dual-process theorists themselves, and the substantial bodies of work on dual processes in cognitive psychology and social psychology remain isolated from each other. The book brings together researchers on dual processes to summarize the latest research, highlight key issues, present different perspectives, explore implications, and provide a stimulus to further work. It includes new ideas about the human mind both by contemporary philosophers interested in broad theoretical questions about mental architecture, and by psychologists specializing in traditionally distinct and isolated fields.
