Freedom of speech on campus

What should be the rules governing campus speech in a liberal democratic society? On one side are those arguing for maximal protections for campus speech analogous to the First Amendment in the United States. On the other are those promoting stricter regulation of speech through formal and informal speech codes. This paper aims to carve a new path in the conversation. Both sides agree that the mission of the university is the discovery and dissemination of knowledge and that achieving this mission requires tolerant and open-minded students, faculty, and administrators. However, neither side has explicitly connected its advocacy for specific speech policies with these shared goals. Our paper advances the conversation by proposing a series of empirically testable mechanisms for connecting speech policies to the desired outcomes. We also argue that focusing on these mechanisms opens the way towards new and more tractable conceptual and normative debates.
