I am a policy expert who studies international research collaboration as it relates to global problems and geopolitical polarization. I understand the need for democratic countries to respond to the the growing strength of authoritarian countries such as China and acute crises like the Russian invasion of Ukraine. But reducing or stopping international research comes with its own risks. It slows down the production of knowledge needed to address long-term global problems and reduces the potential for future scientific collaboration.
First, the collapse of the Soviet Union in 1991 led to an increased openness in global scientific exchange. In particular, there was growth in the number of students from developing and non-Western countries going to universities in the West. This movement formed networks of researchers from many countries. Second, massively collaborative scientific efforts – such as the Human Genome Project – as well as the ever-growing importance of expensive, large research laboratories and instruments have fueled international collaboration. Finally, the digital revolution has made it much easier to communicate and share data across borders. This all resulted in collaborative and fruitful research in many fields including gene technology, climate science and artificial intelligence.
