“Caring about users and their lives is absolutely at the core of user-centered design. Curiosity is a natural outcome of caring, and it is the single greatest contributor to effective user research… Caring and curiosity engender personal investment, and investment motivates a researcher to develop a deep understanding of users.”
– Demetrius Madrigal and Bryan McClain
