Science is at the core of a healthy democracy. But for years, presidential administrations have, in differing ways, sidelined scientific evidence and attacked scientific integrity.
Below is a running list of attacks on science. They include disappearing data, silenced scientists, suppressed studies, and other assaults on science-based policy. The list provides a representative sample of threats to the federal scientific enterprise—and a warning of what we face in the future. More information can be found in our peer-reviewed study and in our data repository.
