Debra Mashek might still be teaching college if she hadn't attended an eye-opening academic conference a few years ago.
One of the speakers asked a roomful of her peers, all social psychologists, to stand if they were politically conservative.
Out of several hundred attendees, "one person stood up," Mashek remembers. "It was striking."
In February, Mashek left what she calls her dream job, as a psychology professor at California's Harvey Mudd College, to devote herself to a new mission: bringing "viewpoint diversity" to the United States' campuses.
She's now executive director of Heterodox Academy, a bipartisan group of professors and graduate students who believe that higher education needs a refresher course in the art of "constructive disagreement."
The New York-based advocacy group, which was founded in 2015, is part of a fledgling movement pushing back against what many see as the chilling of dissent on campus. "Colleges and universities are grappling with this," she said. "Nobody thinks there are obvious simple solutions."
The goal of her group, said Mashek, is not to promote any political agenda — or demand some kind of "affirmative action" for conservatives on campus. Instead, she said, the members share a concern that too much groupthink is bad for higher education, and that colleges can and should do something about it.
As the group says on its website: "When nearly everyone in a field shares the same political orientation, certain ideas become orthodoxy, dissent is discouraged, and errors can go unchallenged. To reverse this process, we have come together to advocate for a more intellectually diverse and heterodox academy."
