In this paper, Caitlin Murphy Brust and Hannah Widmaier begin with the assumption that highly selective institutions of higher education in the United States have a duty to promote civic equality. They employ Wendy Salkin's theory of informal political representation to examine how highly selective institutions should go about promoting civic equality. According to Salkin's theory, someone serves as an informal political representative (IPR) when they speak or act on behalf of others, without having been selected to do so via a systematized selection procedure. Brust and Widmaier argue that as part of their civic educational missions, highly selective institutions should "educate their students for informal political representation," and this includes equipping students to (1) serve as effective IPRs, (2) be responsible audience members to others' informal political representation, and (3) deliberate carefully and with open-mindedness about when they should or should not take on the role of IPR. Brust and Widmaier examine two types of injustice that students from marginalized communities face at highly selective institutions, and they explore how education for informal political representation might ameliorate those injustices. The authors conclude by offering some practical suggestions to institutional policymakers and educators.
