The introduction presents the main arguments of the book and the theoretical and historical background guiding the analysis, proposing a shift in approaches to artificial intelligence on the basis of a new assumption: that what machines are changing is primarily us: humans. It introduces the concept of “banal deception,” which describes deceptive mechanisms and practices that are embedded in media technologies and contribute to their integration into everyday life. Five key characteristics of banal deception are outlined and discussed: first, its everyday and ordinary character; second, its functionality and the fact that it always has some potential value to the user; third, its obliviousness, or the fact that the deception is not understood as such but taken for granted; fourth, its low definition, which refers to the fact that it demands participation from users in the construction of sense; and fifth, that banal deception is not just imposed on users but also “programmed” by designers and developers.
