Words Matter, Actions Have Impact: Updating the NIH Mission Statement

I’ve previously written and spoken about how diverse perspectives are essential to innovation and scientific advancement. Scientists and experts with different backgrounds and lived experiences can offer diverse and creative solutions to solve complex problems. We’re taking steps to create a culture within the biomedical and behavioral research enterprise of inclusion, equity, and respect for every member of society. We are also working to strengthen our efforts to include populations in research that have not been historically included or equitably treated. As part of our effort to ensure that all people are included in NIH research, we’re updating our mission statement to reflect better the spirit of the agency’s work to optimize health for all people.
