You’ve almost certainly heard some of the following terms: cisgender, fat shaming, heteronormativity, intersectionality, patriarchy, rape culture and whiteness.

The reason you’ve heard them is that politically engaged academicians have been developing concepts like these for more than 30 years, and all that time they’ve been percolating. Only recently have they begun to emerge in mainstream culture. These academicians accomplish this by passing off their ideas as knowledge; that is, as if these terms describe facts about the world and social reality. And while some of these ideas may contain bits of truth, they aren’t scientific. By and large, they’re the musings of ideologues.

How did this happen? How have those working in what’s come to be called “grievance studies” managed to extend their ideas far beyond the academy, while convincing people that their jargon adds something meaningful to public discourse? Biologist Bret Weinstein, who was run out of Evergreen State College by a leftist mob in 2017, calls the process “idea laundering.”

It’s analogous to money laundering. Here’s how it works: First, various academics have strong moral impulses about something. For example, they perceive negative attitudes about obesity in society, and they want to stop people from making the obese feel bad about their condition. In other words, they convince themselves that the clinical concept of obesity (a medical term) is merely a story we tell ourselves about fat (a descriptive term); it’s not true or false—in this particular case, it’s a story that exists within a social power dynamic that unjustly ascribes authority to medical knowledge.

Second, academics who share these sentiments start a peer-reviewed periodical such as Fat Studies—an actual academic journal. They organize Fat Studies like every other academic journal, with a board of directors, a codified submission process, special editions with guest editors, a pool of credentialed “experts” to vet submissions, and so on. The journal’s founders, allies and collaborators then publish articles in Fat Studies and “grow” their journal. Soon, other academics with similar beliefs submit papers, which are accepted or rejected. Ideas and moral impulses go in, knowledge comes out. Voilà!
