A new analysis traces how policies introduced by the Trump administration since January 2025 have combined to constrain public health research. The report, “From Anecdote to Evidence,” examined 4,200 coded extracts from 244 scholarly and news sources covering incidents through June 2026.
Published last month by the advocacy group Defend Research and Research Consulting, the analysis used artificial intelligence to identify how often sources described different ways of limiting research at individual, institutional and system levels. Its authors said the aim was to show how measures that might appear isolated can form a broader pattern.
The most frequently cited mechanism was conditioning federal funding, with 253 references. The report included cases in which grants were frozen until institutions agreed to change campus policies. Other prominent mechanisms were altering public records, cited 173 times, and reducing agency capacity through firings and consolidations, cited 163 times.
Research Consulting managing director Rob Johnson told Inside Higher Ed that changes to federal websites and datasets could make it harder to assess the public health effects of government decisions. He said the removal of monitoring and evaluation systems, alongside grant terminations, risks limiting the evidence available to measure those impacts.
The analysis recorded fewer examples of direct pressure on individual researchers: 28 references concerned policing researchers’ speech and 25 described efforts that could discourage discussion or research. The latter included pre-emptive changes to programs and content, as well as self-censorship or avoidance of certain topics.
Johnson said self-censorship is difficult to measure because researchers may respond to the administration’s priorities by changing their research focus or terminology, or by moving away from fields they believe are disfavored. The report describes these indirect responses as part of the wider pattern alongside more direct interventions.
