The NIH conducts a wide range of biomedical and health-related research and does not focus exclusively on diversity, equity, and inclusion (DEI) research.
NIH does nothing else but DEI research.

Why NIH's policy on grants to universities with DEI programs is not cause for widespread alarm
Source: statnews.com
Key Evidence
NIH funds diverse biomedical research fields beyond DEI, including disease-specific studies and public health initiatives.

DEI-related research and policies are a component but not the sole focus of NIH funding.
Legal rulings have addressed specific grant terminations but confirm NIH’s broader research mandate remains intact.
What the Evidence Shows
The claim that the National Institutes of Health (NIH) does nothing else but DEI research is inaccurate and misleading. The NIH is the primary federal agency responsible for biomedical and public health research in the United States, funding a broad spectrum of scientific studies including cancer, infectious diseases, neuroscience, genetics, and many other areas.donoharmmedicine.orgdonoharmmedicine.orgThe FIRST Program: The NIH’s DEI Money Machine While the NIH has incorporated DEI principles into its policies and funding priorities, including some dedicated DEI-related research programs and requirements for diversity commitments in grant applications, this represents only a portion of its overall portfolio.
Recent controversies and legal challenges have focused on NIH actions related to DEI funding cuts or restrictions on certain DEI-related grants,manhattan.institutemanhattan.instituteReform Proposals for the National Institutes of Health (NIH) but these do not imply that NIH's entire mission or research agenda is limited to DEI. Instead, DEI efforts are part of broader initiatives to promote equity in science and research workforce diversity. The NIH continues to fund a vast array of biomedical research unrelated to DEI topics.
Therefore, the claim oversimplifies and misrepresents the scope of NIH activities by suggesting exclusivity where none exists.
