The Group Mind: A Sketch of the Principles of Collective Psychology: With Some Attempt to Apply Them to the Interpretation of National Life and Character

A scientific publication written in the early 20th century. This work delves into the principles of collective psychology, aiming to understand how groups think and behave as cohesive entities, especially in terms of national identity and character. At the start of the book, McDougall addresses the need for a more concrete understanding of psychology that considers the group as an essential unit of analysis. He emphasizes that mental life cannot be understood solely through isolated individuals but must account for the interactions and influences within groups. He outlines his perspective on group psychology, aiming to establish a foundational understanding that will aid in interpreting social behavior and dynamics, ultimately setting the stage for further exploration of how collective mentalities affect national characteristics.
