Leiden Declaration sparks global debate on the future of mathematics and AI

In de media 25 June 2026

The Leiden Declaration has struck a chord around the world. What started as a call from mathematicians for careful and responsible use of AI within their field, has grown into an international debate about the future of science in an era of unprecedented technological change.

The declaration has sparked a wider conversation about reliability, authorship and responsibility in the age of AI. The Leiden-based researchers involved received attention not only in the Netherlands, but also in international media including The New York Times, Scientific American and The Indian Express.

From media attention to scientific debate

The declaration has also prompted a lively discussion within the scientific community. While many welcomed the call for clear guidelines on the responsible use of AI, others argued that the technology is set to become an integral part of scientific practice and should be embraced for the opportunities it creates. At the same time, some felt the declaration did not go far enough.

The impact also reached leading scientific media. Nature endorsed the Leiden Declaration in an editorial, highlighting the importance of human judgement, transparency and fairness in science. According to Nature, the declaration provides an important starting point for broader discussion about the role of AI in science beyond mathematics.

The Declaration also sparked significant discussion on social media. On platforms such as X, Reddit and Bluesky, the statement was widely shared and debated, with mostly supporters but also critics joining the conversation. ‘Don’t let math become property,’ wrote one person. ‘The first week in my class will now be dedicated to the Leiden Declaration’, wrote another.

Thousands of endorsements, many prominent names

More than 2,300 signatories worldwide have now endorsed the declaration. Several prominent scientists and thinkers have expressed their support, including Robbert Dijkgraaf. The theoretical physicist, honorary doctor of Leiden University and former Dutch Minister of Education, Culture and Science, said:

‘Scientific research is in the midst of a major transformation through the impact of AI, and mathematics is one of the disciplines most fundamentally affected through automated proof generation and machine-generated reasoning. It is therefore more important than ever that the mathematical community comes together to establish clear guidelines and shared standards, to safeguard not only the practice of mathematics but its deeper purpose: the cultivation of understanding, judgement and human insight.’
