The book begins by defining subliminal perception and fundamental principles of sensory processing. It then progresses by rigorously analyzing key experimental studies in perceptual psychology, evaluating the methodologies and findings. A significant portion examines the real-world applications of subliminal messaging within advertising and propaganda, considering factors such as message type, target audience, and environmental context. It differentiates itself by focusing on a fact-based analysis of available empirical evidence, ultimately leading to a nuanced understanding of when and how subliminal messaging might be effective, and what limits its influence.
