Our main goal is to improve understanding of how intelligence and security services operate, how they are embedded in broader political, bureaucratic, and societal contexts, and how their methodologies can be complemented.

This article explores an emerging “cultural turn” in intelligence studies, which, if fully realized, could entail the expansion of the discipline to include new methodologies and theories, and a more integrative understanding of historical causality that locates intelligence agencies within the widersocio-cultural…

Artificial Intelligence and Ethics at the Police

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

Can dynamic testing provide us with insight in children’s potential for learning?

Since the Second World War, intelligence and security services have played an important role in policy and decision making, particularly with regards to a state’s national security. In this minor programme we study both the organisations, their working methods, their analysis techniques, as well as…

GLOBALINT is a pioneering study of intelligence in the Global South. It asks ‘how do (un)democratic shifts in political governance impact intelligence services in contexts of violent conflict?

Access to information is a human right (United Nations, 1948). Information technology, such as search engines and recommender systems, has become the key mediator and facilitator to connect people to information (White, 2016). Conversational artificial intelligence (AI) technology is increasingly being…

Leiden University has long had a special interest in and relationship with China.

Hybrid Intelligence (HI) is the combination of human and machine intelligence, expanding human intellect instead of replacing it. HI takes human expertise and intentionality into account when making meaningful decisions and perform appropriate actions, together with ethical, legal and societal values.…

The Creative Intelligence Lab is an interdisciplinary place which connects researchers with different backgrounds across the cognitive and computer sciences.

Why, then, do governments choose to disclose intelligence and what factors shape how they do so?

The WARN project seeks to understand why certain warnings fail to reach and impact decision makers in time to avert crisis.

The Creative Intelligence Lab (CIL) is an interdisciplinary research lab that connects researchers with different backgrounds across the cognitive and computer sciences. It is affiliated to the Media Technology MSc program. Researchers and students from the Media Technology group play a large role in…

This edited volume explores how artificial intelligence (AI) is transforming international conflict in cyberspace.

The development of smart cars, video games that adapt to your gaming behavior, law enforcement assigning your neighborhood a risk score, insurance rates determined by your behavior, finding your perfect match via an app: Artificial Intelligence (AI) is rapidly and radically transforming our interactions…

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

Indonesia is, and has long been, an important object of study for academics in Leiden in a wide range of disciplines.

De minor Data Science & Artificial Intelligence geeft een toegankelijke introductie tot de theorie en praktijk van datawetenschap en kunstmatige intelligentie. Studenten leren de basis van data-analyse en patroonherkenning in grote gegevensverzamelingen, hoe computers leren en ook het interpreteren…

In the track Intelligence and National Security you will be introduced to intelligence and security services in their political, societal, and bureaucratic contexts. The track will give you a thorough understanding of the modus operandi of these agencies, their interaction with the surrounding world,…

Leiden University has signed a substantial number of Memoranda of Understanding with institutions in Latin America and the Caribbean Region.

This study examines the mutual intelligibility between all 225 pairs of 15 Chinese dialects, in two main branches, i.e., six Mandarin dialects and nine non-Mandarin (Southern) dialects.

Who are open-source intelligence activists and how reliable are their contributions to public understanding of Russia’s war in Ukraine?

Can we develop a platform for raw materials intelligence?

Shah recently wrote an op-ed for the Commentaries series of the Istituto Affari Internazionali in Rome, which has been published online. The piece is on India’s performance and priorities regarding the UN sustainable development goals (SDGs) and collaboration with the EU.

The focus of the Bachelor Data Science & Artificial Intelligence is on computer science, and its applications in Artificial Intelligence. You will receive a strong basis in mathematics, statistics and computer science, combined with advanced knowledge of machine learning, cognitive science, human-robot…
