Animals in behavioral research face chronic stress that compromises both welfare and research validity.
Behavioral research uses millions of rodents, fish, and other species in ways that cause chronic welfare harm. Standard testing protocols including repeated exposure to novel environments and social isolation create sustained stress that compromises both animal welfare and research validity. Chronic stress alters the very behavioral processes being studied, undermining reproducibility. Welfare improvements including enrichment, group housing, and refined testing protocols improve both animal welfare and data quality simultaneously.
