How does design shape the world? This week, Paul Ford and Rich Ziade finish their conversation with Michael Bierut, a partner at Pentagram, and Jessica Helfand, senior critic at the Yale School of Art. Topics discussed include the public’s perceptions of designers’ work, collective interest in logos and branding, the danger of creating in pursuit of positive feedback, publishing personal writing on the internet, and their recent appointments as the first design faculty in the Yale School of Management.
