A new national survey of 478 higher education institutions in the U.S. found that 9 in 10 restrict free speech in some capacity on campus but nearly half maintain policies that “impermissibly restrict online speech.”

The study was conducted by FIRE, the Foundation for Individual Rights in Education, a nonpartisan, nonprofit organization dedicated to defending and sustaining the individual rights of students and faculty members at American colleges and universities. These rights include freedom of speech, freedom of association, due process, legal equality, religious liberty, and sanctity of conscience.
