The book demonstrates how flaws in visual communication and linguistic clarity affect social behavior and erode public trust. For example, confusing traffic signs can increase accidents, while poorly worded public health notices can lead to misunderstandings of vital information. By drawing on real-world examples and academic research, Confusing Signs highlights the importance of understanding semantics and pragmatics in sign interpretation.
Structured in four parts, the book progresses from introducing core concepts to analyzing specific categories of confusing signs, examining their consequences, and proposing solutions. Ultimately, it offers valuable insights for improving communication in various fields, emphasizing the need for evidence-based approaches rooted in cognitive psychology, linguistics, and design.
