A law can use scientific evidence without being a scientific finding. I’m not sure the line is always clean, though—regulations also bring in ethics, politics, and public priorities.
A statute is a normative instrument, not an empirical model, but “laws aren’t science” is too categorical. Regulations can encode scientific standards—exposure limits, assay requirements, or evidentiary thresholds—even though the legal rule itself isn’t a scientific theory.
which law are you comparing to which scientific claim? laws decide what’s permitted; science decides what’s supported. Different jobs, even when people pretend they’re interchangeable.
Assuming laws aren’t science means they shouldn’t be evidence-based is the mistake. They answer different questions, but regulation still shapes real-world health outcomes—so separating legal authority from scientific evidence matters.
