For the first time since Gallup began tracking public attitudes on animal testing more than two decades ago, more Americans believe medical testing on animals is morally wrong than morally acceptable.
According to Gallup’s latest findings, 48% of Americans now say medical testing on animals is morally wrong, while 45% say it is morally acceptable. While the margin is narrow, the significance is difficult to overstate: it marks the first time public opinion has shifted against animal experimentation since Gallup began asking the question.
This milestone reflects a broader transformation taking place in both society and science.
For decades, animal experimentation was often viewed as a necessary component of biomedical research. Today, however, growing public awareness of animal welfare concerns, combined with rapid advances in human-relevant technologies, is prompting many people to question whether animal-based research remains the best path forward.
The shift in public opinion comes at a time when researchers, regulators, and policymakers are increasingly exploring alternatives that can more accurately reflect human biology while avoiding the ethical concerns associated with animal experimentation.
Science Is Changing
The conversation around animal testing is no longer limited to ethics alone.
A growing body of evidence suggests that many non-animal approaches can provide insights that are more directly relevant to human health and disease than traditional animal models. Technologies such as organoids, organ-on-a-chip systems, advanced computational models, artificial intelligence, and other New Approach Methodologies (NAMs) are helping researchers study human biology in ways that were impossible just a generation ago.
Federal agencies have begun to take notice.
Recent initiatives across the National Institutes of Health, Food and Drug Administration, Environmental Protection Agency, and other agencies reflect increasing interest in modernizing research and testing frameworks. Investments in human-relevant science continue to grow as policymakers seek methods that are not only more humane, but also more predictive of human outcomes.
While animal experimentation remains deeply embedded within many areas of biomedical research, momentum is building toward a future where animals play a significantly reduced role.
Public Expectations Are Evolving
Gallup’s findings suggest that public expectations are changing alongside the science.
Americans are increasingly asking whether animal experimentation remains justified when alternative approaches are becoming more sophisticated and accessible. They are also asking whether research systems should continue relying on methods developed decades ago when new technologies may offer better ways to study human disease, evaluate safety, and develop treatments.
This does not mean the transition away from animal experimentation will happen overnight. Scientific validation, regulatory acceptance, and infrastructure development all take time.
But public opinion often serves as an important indicator of where society believes progress should be heading.
The latest Gallup data suggest that more Americans now see the ethical costs of animal experimentation as outweighing its perceived benefits. That shift has implications not only for policymakers and regulators, but also for research institutions, funding agencies, and the broader scientific community.
The Future Is Human-Relevant
At NAVS, we have long advocated for a future in which scientific progress no longer depends on animal suffering.
Through our support of researchers developing innovative alternatives, our advocacy for policy reform, and our efforts to increase public awareness, we are working to accelerate the transition toward research methods that are both scientifically advanced and ethically responsible.
The next generation of biomedical research is already taking shape. Human-relevant technologies are expanding our understanding of disease, improving our ability to predict human responses, and creating new opportunities to reduce and replace animal use.
Gallup’s latest findings suggest the public is ready for that future.
The challenge now is ensuring that our research systems, funding priorities, and regulatory frameworks evolve to meet it.
The future of biomedical research is human-relevant—and increasingly, the public agrees.
A Roadmap Forward
The shift reflected in Gallup’s latest polling is more than a change in public opinion. It is a sign that society is increasingly ready for a different vision of scientific progress—one that no longer accepts animal experimentation as the default.
At NAVS, that vision is embodied in Crossroads 2029, our strategic initiative to accelerate the transition from animal-based research to human-relevant science by the end of this decade.
Crossroads 2029 recognizes that meaningful change requires more than technological innovation alone. It requires coordinated action across research institutions, funding agencies, regulators, policymakers, and the public. By supporting the development and adoption of non-animal methods, advocating for policy reform, expanding transparency, and investing in the next generation of scientific leaders, NAVS is working to help build the infrastructure necessary for lasting change.
The latest Gallup findings suggest that public sentiment is increasingly aligned with this mission. As confidence in human-relevant technologies grows and support for animal experimentation declines, the opportunity to transform the research enterprise has never been greater.
The question is no longer whether change is possible. The question is how quickly we can make it happen.
