Updates to this feature are currently paused as we assess the best way to monitor and expose the large number of attacks on science that we're seeing from the current administration.
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.
