Persuasion is an important skill for designers to have—both in design practice itself, and in professional situations. Your ability to put across your message, to get other people to agree with you, to value your work, and to want to work with you, will be central to your career, both inside and outside of design. Equally, understanding what persuades you and others—how we are influenced by other people, by media, by our environment, by design—is a crucial reflective skill to develop in better understanding yourself, those around you, and more widely, society.
