Attacks on Science

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.

Due to the large number of attacks on science we’re seeing from the second Trump administration, we are currently providing regular summaries of documented attacks.

Below is the list of documented attacks on science that occurred under the four previous administrations. They include disappearing data, silenced scientists, suppressed studies, and other assaults on science-based policy. More information on these attacks can be found in our peer-reviewed study and in our data repository.
