Research breakthroughs often come through collaborations − attacks on academic freedom threaten this vital work
**Title: The Erosion of Academic Freedom: A Global Concern for Scientific Research**
At the University of Minnesota, a significant protest erupted among researchers, scientists, and supporters in response to proposed cuts to scientific research funding. These cuts, attributed to perceived ideological biases in academic research, have intensified since President Donald Trump’s second term began and were further exacerbated by the extensive government shutdown in 2025. This alarming trend reflects a broader global issue: the decline of academic freedom, which has been increasingly threatened by political pressures in various countries, including the United States, Hungary, and Argentina. The consequences of these funding cuts and attacks on academic independence are profound, as they not only jeopardize individual researchers but also threaten the collaborative nature of modern scientific inquiry.
Research has shown that academic freedom is crucial for fostering productive collaborations, which are essential for tackling complex global challenges, from vaccine development to renewable energy solutions. The decline in academic freedom has been linked to a decrease in the quality and quantity of scientific output, as evidenced by studies indicating that stronger protections for academic freedom correlate with higher research productivity. The Varieties of Democracy (V-DEM) project highlights these trends, revealing that infringements on academic freedom have been on the rise since the mid-2000s, impacting countries worldwide. For instance, Hungary’s Prime Minister Viktor Orbán effectively forced the Central European University into exile, labeling it as “liberal bias,” while Argentina’s President Javier Milei has disparaged academics as corrupt elites, using this rhetoric to restrict university funding and autonomy.
The implications of diminishing academic freedom extend beyond individual researchers to the very fabric of global research collaborations. As the landscape of scientific inquiry has evolved, the majority of research is now conducted collaboratively, with university-based scientists co-authoring up to 90% of STEMM research papers annually. This collaborative model, which has been pivotal in producing significant scientific advances, is threatened when universities face restrictions on their autonomy. A staggering three-quarters of U.S.-based scientists have considered leaving the country due to these threats, highlighting the precarious position of academic freedom in the U.S. and its potential repercussions on global scientific discovery. As we face pressing global challenges, the need to protect academic freedom has never been more urgent, ensuring that researchers can collaborate freely and innovate effectively for the benefit of society.

Since President Donald Trump took office for the second time, many researchers across academic disciplines have
had their funding cut
because of their
purported ideological bias
. These funding cuts were further exacerbated by the extensive
2025 government shutdown
.
As a team of sociologists
studying universities
,
higher education policy and administration
,
academic freedom
and
science production
, we recognized these cuts as part of a recent global trend of weakened academic freedom. Since the mid-2000s, political attacks on higher education have increased in many countries. Consequently,
academic freedom has declined
in countries as different as India, Israel, Nicaragua and the United Kingdom,
among others
.
For example, for years Hungarian Prime Minister Viktor Orbán accused the internationally respected
Central European University
of “
liberal bias
.” By 2019, he had effectively forced the university and its faculty into exile in Vienna, Austria. Since Argentinian President Javier Milei came to power in 2023, he has made repeated
claims that academics are corrupt elites
. He used this narrative to restrict universities’ autonomy and funding of their research programs.
Today,
most research is done collaboratively
. But research finds that when
individual scholars have less academic freedom
and
universities’ autonomy declines
,
global research collaborations are also threatened
.
The prevalence and complexity of those collaborations that optimize human and material resources has grown, with substantial impact on scientific productivity — what we call the global “collaboration dividend.” Collaborations foster solutions to complex problems, from vaccine development to renewable energy. Diminishing academic freedom erodes these collaboration dividends, which then reduces the quantity and quality of scientific discovery worldwide.
The United Nations Educational, Scientific and Cultural Organization
recommendation concerning the status of higher education teaching personnel
builds on Article 26 of the
Universal Declaration of Human Rights
and urges governments to protect academics from political surveillance and interference on two levels.
First, UNESCO affirms the right of individual faculty to teach, research, share findings and express their expert opinions independently. Second, UNESCO recognizes the right of universities to autonomously make decisions about facilitating research, hiring and promoting faculty, and developing curricula without state interference.
Academic freedom and global collaborations
Data from
the Varieties of Democracy, or V-DEM, project
demonstrate international trends in academic freedom. V-DEM is a large, widely used international dataset based on experts evaluating political developments. It tracks infringements and protections of these rights in every country over the past hundred years. The index we used measures dimensions of academic freedom.
Suppressed in the 1930s by
global economic depression
,
rising fascism and military conflict
, academic freedom reached a low point during World War II. It then rebounded and grew strongly.
More countries began recognizing the benefits of free inquiry and guaranteed independent science, especially from 1980 to the mid-2000s. Nations everywhere expanded the capacity of their universities to undertake scientific research and collaborate across boundaries.
A new global model of the research university
fostered the exponential growth of scientific knowledge.
Also, in part as a defense against totalitarianism, many countries signed on to international agreements upholding academic freedom, such as the
International Covenant on Economic, Social and Cultural Rights
. This agreement declares that the basic human right to an education “can only be enjoyed if accompanied by the academic freedom of staff and students.”
The strengthening of academic freedom paralleled the largest historical expansion of the world’s capacity to undertake research on science, technology, engineering, mathematics and medicine, or STEMM. But over the past decade, freedoms of faculty members and universities began to weaken in many countries, including in the
United States
.
Today,
university-based scientists co-author 85% to 90%
of the several million STEMM research papers produced annually. Large, complex collaborations are increasingly a driving force in discovery. The global expansion of academic freedom enables universities and their scientists to participate in this intensifying collaboration dividend through joint research with colleagues elsewhere.
In studies published between 2024 and 2025, we presented troubling trends about declining academic freedom, collaborations and scientific research at universities in countries across the world.
First, we analyzed individual academic freedom and STEMM production in 17 research productive countries from 1981 to 2007. We found that academic freedom protections
raise the quantity and quality of research
, while infringements on these safeguards lower them.
Second, we found that safeguarding universities’ organizational autonomy also
increases the volume and excellence
of a country’s STEMM research output. Both associations are independent of other influential factors behind countries’ scientific productivity, such as governmental research spending, a country’s wealth or university enrollments.
Third, a related study by others finds that restricting academic freedom
reduces scientists’ and universities’ ability
to effectively participate in international research collaborations.

Diminishing the collaboration dividend
Together, these findings underscore that academic freedom allows researchers to participate in complex collaborations, which in turn increases research production. Most of these collaborations aren’t just facilitated by individual scientists, however. Global collaborations are made up of networks of universities, and declining academic freedom can threaten the ties between these institutions and their scientists’ projects.
The popular image of the solitary genius making isolated breakthroughs is largely a myth. Research teams have steadily increased in size, and “
super-collaborative” groups
of hundreds or even thousands of scientists now work together on complex projects. Together, they produce ever greater amounts of knowledge. Because individual researchers’ output is fairly steady over their careers, real productivity gains in science now
depend on global collaboration and shared resources
. This is true even as the number of scientists grows.

In the early 1980s,
three geographical superhubs
of robust, primarily university-based collaborative research emerged. One is Europe, another is North America. The third, East Asia, is growing rapidly.
By 1980, universities in the European and North American hubs collaborated on publications with scientists in 100 other countries. This number grew to 193 countries by 2010. Currently,
over a fourth of the millions of annual STEMM papers
are the result of international collaborations. This process is heavily dependent on universities and their freedom to pursue science.
Moreover, superhubs can accelerate international collaboration for scientists in other countries not originally in these hubs. Such collaborations enable their universities to leapfrog into new superhub status.
South Korean universities
have been an example of this process over the past several decades.
This collaborative capacity has enabled the production of millions of co-authored papers and scientific advances. For instance, these collaborations allowed for the
rapid development of COVID-19 vaccines
.
Collaborative networks depend on university support, not just individual scientists. This is why our research suggests declining academic freedom at the university level makes them vulnerable. A troubling
three-quarters of U.S.-based scientists
have considered leaving the country in response to threats against academic freedom in the U.S. since early 2025.
This research suggests that at stake here is not only the freedom of scholars and academic institutions, but also the future of discovery itself. Academic freedom is essential for scientists around the world to collaborate, enabling the scientific discoveries necessary for technological innovation, medical breakthroughs, and social and environmental problem-solving.
