JONATHAN HAIDT ON THE CULTURAL ROOTS OF CAMPUS RAGE:

When a mob at Vermont’s Middlebury College shut down a speech by social scientist Charles Murray a few weeks ago, most of us saw it as another instance of campus illiberalism. Jonathan Haidt saw something more—a ritual carried out by adherents of what he calls a “new religion,” an auto-da-fé against a heretic for a violation of orthodoxy.

“The great majority of college students want to learn. They’re perfectly reasonable, and they’re uncomfortable with a lot of what’s going on,” Mr. Haidt, a psychologist and professor of ethical leadership at New York University’s Stern School of Business, tells me during a recent visit to his office. “But on each campus there are some true believers who have reoriented their lives around the fight against evil.”

These believers are transforming the campus from a citadel of intellectual freedom into a holy space—where white privilege has replaced original sin, the transgressions of class and race and gender are confessed not to priests but to “the community,” victim groups are worshiped like gods, and the sinned-against are supplicated with “safe spaces” and “trigger warnings.”

The fundamentalists may be few, Mr. Haidt says, but they are “very intimidating” since they wield the threat of public shame. On some campuses, “they’ve been given the heckler’s veto, and are often granted it by an administration who won’t stand up to them either.”

Yes, the crybullies are a small minority even on most lefty campuses. But they’ve been unrestrained because the administration, basically, supports them. Plus:

Down the hall from Mr. Haidt’s office, I noticed a poster advertising a “bias response hotline” students can call “to report an experience of bias, discrimination or harassment.” I joke that NYU seems to have its own version of the morality police in Islamic countries like Saudi Arabia. “It’s like East Germany,” Mr. Haidt replies—with students, at least some of them, playing the part of the Stasi.

How did we get here, and what can be done? On the first question, Mr. Haidt points to a braided set of causes. There’s the rise in political polarization, which is related to the relatively recent “political purification of the universities.” While the academy has leaned left since at least the 1920s, Mr. Haidt says “it was always just a lean.” Beginning in the early 1990s, as the professors of the Greatest Generation retired, it became a full-on tilt.

“Now there are no more conservative voices on the faculty or administration,” he says, exaggerating only a little. Heterodox Academy cites research showing that the ratio of left to right professors in 1995 was 2 to 1. Now it is 5 to 1.

The left, meanwhile, has undergone an ideological transformation.

At the very moment where higher education is in trouble, it is dominated by a mindset that sets it in opposition to the mainstream culture. This will end well:

“People are sick and tired of being called racist for innocent things they’ve said or done,” Mr. Haidt observes. “The response to being called a racist unfairly is never to say, ‘Gee, what did I do that led to me being called this? I should be more careful.’ The response is almost always, ‘[Expletive] you!’ ”

He offers this real-world example: “I think that the ‘deplorables’ comment could well have changed the course of human history.”

I certainly hope so.
