A professor at Duke has convinced his students to open up classroom discussions. The project could not happen in the absence of trust. An excerpt from the WSJ:

To get students to stop self-censoring, a few agreed-on classroom principles are necessary. On the first day, I tell students that no one will be canceled, meaning no social or professional penalties for students resulting from things they say inside the class. If you believe in policing your fellow students, I say, you’re in the wrong room. I insist that goodwill should always be assumed, and that all opinions can be voiced, provided they are offered in the spirit of humility and charity. I give students a chance to talk about the fact that they can no longer talk. I let them share their anxieties about being socially or professionally penalized for dissenting. What students discover is that they are not alone in their misgivings.

Having now run the experiment with 300 undergraduates, I no longer wonder what would happen if students felt safe enough to come out of their shells. They flourish. In one class, my students had a serious but respectful discussion of critical race theory. Some thought it harmfully implied that blacks can’t get ahead on their own. Others pushed back.

My students had an honest conversation about race, but only because they had earned each other’s trust by making themselves vulnerable. On a different day, they spoke up for all positions on abortion. When a liberal student mentioned this to a friend outside class, she was met with disbelief.
