An Introduction to Social Psychology

William McDougall's An Introduction to Social Psychology (1908) popularized a theory of instinct as an innate urge driving behavior towards a goal. This purposive psychology, rooted in distinct emotional states, influenced social sciences like economics. However, the subjective nature of emotions and opposition from behaviorists, who emphasized objective, observable evidence, led to a decline in instinct-based explanations. Social psychology, as a field, scientifically studies individual behavior within social and cultural contexts, evolving from speculative ideas to empirical investigation. It explores how personality, attitudes, and motivations are influenced by and influence social groups.1234
