The Pomona Student Union (PSU) facilitates the discussion of political and social issues on campus. They describe their mission as "promoting honest and open dialogue in order to challenge the assumptions of students and the wider campus community." They hold discussions, panels, and debates with prominent speakers with the goal of stimulating conversation and creating an environment in which all viewpoints are represented. Notable speakers the PSU has brought to Pomona include Jon Meacham, Mari Matsuda, Sam Harris, Nadine Strossen, Michael Isikoff, and Slavoj Žižek.
