The more we know about the situational causes of psychological phenomena, the less need we have for postulating internal conscious mediating processes to explain these phenomena. As the purview of social psychology is precisely to discover those situational causes of thinking, feeling, and acting in the real or implied presence of other people, it is hard to escape the forecast that as knowledge progresses regarding social psychological phenomena there will be less of a role played by free will or conscious choice in accounting for them. In other words, because of social psychology's natural focus on the situational determinants of thinking, feeling, and doing, it is inevitable that social psychological phenomena increasingly will be found to be automatic in nature. This book addresses automaticity and how it relates to social behaviour. The lead article, written by John Bargh, argues that social psychology phenomena are essentially automatic in nature, as opposed to being mediated by conscious choice or reflection. Bargh maintains that an automatic mental phenomenon is that which occurs reflexively whenever certain triggering conditions are in place; when those conditions are present, the process runs off autonomously, independently of conscious guidance. In this article, he focuses on these preconscious automatic processes that can be contrasted with postconscious and goal-dependent forms of automaticity which depend on more than the mere presence of environmental objects or events. Because social psychology, like automaticity theory and research, is also largely concerned with phenomena that occur whenever certain situational features of factors are in place, social psychology phenomena are essentially automatic.
