Free Speech & Social Media

Free Speech & Social Media

Safeguarding the vitality and integrity of public discourse online

Conversations that once took place in parks, sidewalks, and public squares now take place largely online, and often on privately owned social media platforms. As a society, we are just beginning to grapple with the question of how the First Amendment and free speech principles should apply in these digital spaces.

Our work seeks to illuminate the forces that are shaping public discourse online, and to ensure the inclusivity and integrity of digital spaces that are increasingly important to our democracy.
