State Laws Targeting 'Divisive Concepts' Prompt Widespread Self-Censorship Among Researchers
Legislation in more than 20 states since 2021 has created a climate where academic researchers increasingly avoid certain topics in their work. A major national survey released in April 2026 by Ithaka S+R reveals the extent of this shift, with nearly one-third of researchers in affected states reporting they have steered clear of lines of inquiry due to these policies.
The laws, often framed around restrictions on teaching or studying concepts related to race, gender, diversity, equity, and inclusion, or critical race theory, have prompted measurable changes in research behavior. Twenty percent of all surveyed researchers across the United States said they had avoided pursuing specific topics in the past five years because of state law or policy changes. That figure rises to 29 percent among those working in states with such legislation in place.
Background on the Legislation and Its Reach
Beginning in 2021, lawmakers in Republican-led states introduced measures aimed at limiting what they described as divisive content in public education, including higher education. These statutes typically prohibit instruction that suggests individuals bear responsibility for historical actions based on their race or sex, or that certain groups are inherently oppressive or privileged. By early 2026, 21 states had enacted versions of these laws, affecting curricula, faculty hiring, training programs, and research agendas at public colleges and universities.
Proponents argue the measures protect students from ideological indoctrination and ensure balanced instruction. Critics contend the laws chill free inquiry and academic freedom, particularly in fields such as history, sociology, education, and the humanities. The Ithaka S+R report underscores how these policies extend beyond the classroom into research laboratories and scholarly publishing decisions.
The Ithaka S+R National Survey: Methodology and Scope
Ithaka S+R, a research and consulting organization focused on higher education and libraries, fielded its survey in fall 2025 among 4,003 academic researchers nationwide. The study examined both state-level restrictions and federal policy shifts, including changes to grant funding priorities. Respondents represented a broad cross-section of disciplines and institution types, with particular attention to public universities in states that had passed divisive-concepts legislation.
Key questions probed whether researchers had altered their agendas, avoided certain topics, or considered relocating. The findings provide one of the most comprehensive snapshots to date of how state policy is reshaping the research enterprise.
Key Findings on Self-Censorship Rates
Among researchers in states with divisive-concepts laws, 29 percent reported personally avoiding research topics because of those statutes. Nationally, the figure stood at 20 percent. At public institutions in affected states, 66 percent of respondents said their choice of research topics or freedom of inquiry had been impacted in some way.
Forty-eight percent of researchers in states with the laws described them as limiting academic freedom over their research. Ten percent of faculty working in such states indicated they had sought positions in more permissive states. These patterns appear across disciplines, though humanities and social sciences researchers reported higher rates of adjustment than those in many STEM fields.

Disciplinary and Institutional Variations
Researchers in history, education, sociology, and gender studies described the most direct pressure to reframe or abandon projects. Several noted that proposals involving race, immigration, or climate policy now face heightened internal review or external funding challenges. Public universities reported greater effects than private institutions, consistent with the laws' primary application to state-supported entities.
Early-career scholars and those without tenure expressed heightened caution, fearing that controversial work could jeopardize promotion or grant success. Senior faculty reported similar adjustments but often described them as strategic rather than absolute avoidance.
Perspectives from Researchers and Administrators
Faculty members interviewed for related coverage described a pervasive sense of caution. One historian at a public university in a restrictive state explained that she had shifted a planned book project away from certain archival materials after colleagues warned of potential legislative scrutiny. Administrators at affected institutions reported increased time spent reviewing syllabi, research proposals, and public communications to ensure compliance.
Some researchers welcomed the laws as a corrective to perceived ideological capture, arguing that self-censorship claims overstate the impact and that alternative viewpoints now receive fairer consideration. Others viewed the changes as a direct threat to the pursuit of knowledge, with long-term consequences for innovation and public trust in higher education.
Effects on Academic Mobility and Talent Retention
The survey found that one in ten researchers in states with the laws had actively explored opportunities elsewhere. While actual departures remain modest, the data suggest a potential brain drain from public research universities in affected states. Recruiting committees at institutions in states without such laws reported increased interest from candidates citing academic freedom concerns.
Graduate students and postdoctoral researchers appear especially mobile, with some choosing programs or positions based on state policy environments. This trend could reshape departmental demographics and research output over the next decade.
Broader Implications for U.S. Higher Education
The Ithaka S+R findings point to a national chilling effect that extends beyond the 21 states with explicit legislation. Researchers in states without such laws also reported heightened caution, suggesting the debate itself influences behavior. Public universities, which educate the majority of students and conduct a large share of publicly funded research, face particular pressure.
Longer-term consequences may include reduced diversity of research topics, slower progress on complex social issues, and diminished international competitiveness. University leaders and scholarly societies have begun discussing collective responses, including legal challenges and advocacy for stronger protections of academic freedom.

Institutional Responses and Advocacy Efforts
Some public universities have issued statements reaffirming commitments to free inquiry while implementing compliance training. Faculty senates have passed resolutions urging caution in legislative engagement. National organizations representing higher education have filed amicus briefs in ongoing litigation and developed resources to help researchers navigate the new landscape.
Private institutions, less directly constrained by the state laws, have positioned themselves as alternatives for scholars seeking greater latitude. This dynamic may accelerate stratification between public and private research sectors.
Future Outlook and Potential Pathways Forward
As legislative sessions continue and court cases proceed, the policy environment remains fluid. The Ithaka S+R report recommends that institutions strengthen internal policies protecting research autonomy, expand professional development on academic freedom, and engage proactively with policymakers. Researchers are advised to document decisions and seek support from disciplinary associations.
Longer-term solutions may involve renewed emphasis on shared governance, clearer statutory language distinguishing between K-12 and higher education, and federal-level protections for academic inquiry. The survey underscores that the choices made in the coming years will shape the direction of American scholarship for a generation.
