Overall Rankings
The Overall Score combines seven unique dimensions to identify the top ranked college campuses for student free speech and open inquiry. The top-ranked colleges have the highest average score among all students surveyed and have the most open environments for free speech. Read more on how this ranking was calculated.
The Liberal to Conservative ratio (after the first school on the list, you'll need to click the down arrow at right of each listing to see added data) is particularly interesting.
I giggled when it showed University of Chicago as a bastion of free speech - just listen to one of Natalie Winter's examples of getting canceled by her entire sorority and her journalism professors while she was working full time for National Pulse and later co-host Steve Bannon's War Room.
