Design does not only shape forms, images, or interfaces, it also shapes our perception and our judgments. Every design decision frames content, creates atmospheres, and directs meaning. In this sense, design becomes a powerful instrument: it can manipulate, distort, and amplify, but it can also reveal, clarify, and encourage critical reflection. For designers, it is therefore crucial to engage with questions of design ethics and techniques: How biased is our design process itself? How do choices of words and images, interface logics, or spatial arrangements influence perception? Where does subtle manipulation begin, and where does design open up spaces for reflection? In this seminar, we will approach this field of tension through practical workshops and theoretical input sessions as an entry point into the topic. The course thrives on the active participation of the students. Building on these exercises, students will then develop their own design-based exploration of the subject. The choice of techniques and media is open and should be adapted to each student’s abilities and ideas. What matters is that the projects make the questions of distortion, manipulation, and reflection in and through design visible and debatable.
