Students Exposed to DEI Materials More Likely to Endorse Hate Speech, Study Finds
A Rutgers University study finds that students exposed to popular diversity training materials became significantly more likely to endorse dehumanizing statements about marginalized groups, casting doubt on billions in annual DEI spending.
The diversity training was supposed to make students less prejudiced. It did the opposite. That sentence should end the debate — but it won't, because the DEI industry has too much money at stake to let the facts get in the way.
A Rutgers University study found that students exposed to popular diversity training materials became significantly more likely to endorse statements comparing marginalized groups to "parasites" and "viruses." These weren't fringe materials. Participants reviewed DEI content from the most prominent names in the field — Ibram X. Kendi and Robin DiAngelo — and came out the other end more bigoted than when they went in. Those exposed endorsed Hitler's demonization statements at striking rates: 35.4 percent agreed that Brahmins are parasites, 33.8 percent agreed they are viruses, and 27.1 percent agreed they are the devil personified.
Read that again. This is the product of an $8 billion-per-year industry.
The findings land at a moment when companies and universities pour vast sums into diversity, equity and inclusion programs designed to "reduce bias and improve workplace cohesion". Harvard Kennedy School's Iris Bohnet estimates $8 billion is spent annually on DEI programs. A 2023 Pew Research Center study found 52 percent of American workers attend DEI meetings or training events at work. The scale of this enterprise is staggering — and almost entirely unsupported by evidence that any of it works.
The Rutgers researchers put it bluntly: some anti-oppressive DEI narratives can engender a hostile attribution bias and heighten racial suspicion, prejudicial attitudes, authoritarian policing, and support for punitive behaviors — even without evidence of a transgression. DEI instruction, they found, has been shown to increase prejudice and activate bigotry by pushing existing stereotypes to the forefront of participants' minds, or by implanting new biases they had not previously held. This is not a bug. Given the ideological framework baked into most DEI curricula, it may well be a feature.
The broader case against diversity ideology has been building for decades. Harvard political scientist Robert Putnam's landmark 2007 study of 29,000 people across 41 U.S. communities found that in diverse communities, neighbors trust one another about half as much as in homogeneous settings. "In ethnically diverse neighbourhoods residents of all races tend to hunker down," Putnam wrote. "Trust (even of one's own race) is lower, altruism and community cooperation rarer, friends fewer." Putnam, notably, was a progressive who sat on these findings for years because he found them politically inconvenient — which tells you everything about why this research struggles to reach mainstream discourse.
Workplace data reinforces the picture. "Nearly all Fortune 500 companies do training, and two thirds of colleges and universities have training for faculty," Frank Dobbin and Alexandra Kalev wrote in Anthropology Now in 2018. "Yet hundreds of studies dating back to the 1930s suggest that antibias training does not reduce bias, alter behaviour or change the workplace." A 2022 Frontiers in Psychology study examining workforce diversity found it was positively related to interpersonal conflict, driving up negative affect among employees. A Proaction International study found 31 percent of employees report conflicts they attribute to racial or cultural differences — suggesting DEI programs are not resolving the tensions they were built to address. They may be creating them.
Some researchers have tried to rescue the diversity agenda by arguing that economics, not ethnicity, is the real culprit — that if you just reduce material deprivation, diversity stops being a problem. A 2025 UCL study claimed that once poverty is controlled for, the link between diversity and social fragmentation disappears. This is a convenient reframe that should be treated with skepticism. Controlling away the variables that make diversity contentious in practice — competition for housing, jobs, public services — doesn't make those real-world conditions disappear. It just makes the data look cleaner. The argument amounts to: "diversity would work fine in a friction-free utopia." We don't live in one, and policy should be made for the world as it is.
The DEI industry has had decades and billions of dollars to prove its case. It has produced the opposite of what it promised — and that pattern is too consistent, too deliberate, and too convenient for certain political interests to dismiss as mere incompetence. Programs that inflame racial suspicion, deepen distrust between neighbors, and manufacture grievance in workplaces don't fail at reducing division. They succeed at producing it. When you follow the incentives — the political movements funded by identity fragmentation, the activist class whose power depends on an endlessly aggrieved population, the electoral math that requires racial blocs voting in lockstep — the results start to look less like failure and more like the point. The diversity agenda was never really about unity. Unity would have put them out of business.
