The "Collective Psychology" series aims to explore the internal exchanges that occur within individuals in a group setting. It not only examines the psychology of temporary and irrational crowds but also that of organized and stable collectives such as nations and classes, emphasizing the dynamic psychology of "clusters" and "crowds" and studying how "a group of people" think and act. Therefore, in this process, I am more concerned with whether I am expressing something or not, rather than overly focusing on "whether it looks like it or not". I approach it like shooting black-and-white photos, bypassing color to directly capture the raw state of the psychological process.
