How did college become such a minefield? A sociologist who has been tracking the polarization of higher education reveals what went wrong, what students are saying, and where we can find hope. Imagine arriving on campus, full of excitement and anticipation, only to find that seemingly innocuous conversations can quickly turn into an ideological litmus test. Over the last ten years, politics has seeped into every corner of college life, plunging students into a morass of self-censorship and social exclusion. How can anyone hope to learn when the cost of speaking freely is so high? A sociologist known for his groundbreaking work on campus politics, Neil Gross spoke to hundreds of students and faculty at America's top colleges and universities and polled thousands more to get behind the headlines and make sense of how epic polarization, cancel culture, battles over race and gender, and intrusive political assumptions baked into the curriculum have remade the college experience.
