What will it be like to study at Leiden University in 2075?

What political factors affect the speed or duration of EU legislative decision-making?

This thesis examines the complexity of legislative decisions within the EU, with a specific focus on the Council of the EU.

Our project focuses on the analysis of decision-making processes in the European Union (EU) and explores how approaches and tools to understand decision-making found in both the Natural and the Social Sciences can be linked, knowledge between these traditions exchanged and synergies utilized. To explore…

Müller, Braun & Fraussen examine the conditions under which commissioners appear in the news and which communication strategies they pursue.

How do processes of coalition-formation influence patterns of decision-making in the European Union?

As a research project between four Jean Monnet Chairs - two located in Europe, one in Canada and one in the U.S. -- the project DEUBAL has been approved in 2010 for co-financing by the European Commission. DEUBAL aims to study changes in European decision-making due to the Lisbon Treaty, by a combination…

Simona Demková, Assistant professor at the Europa Institute of Leiden University, publishes her book ‘Automated Decision-Making and Effective Remedies: The New Dynamics in the Protection of EU Fundamental Rights in the Area of Freedom, Security and Justice’.

How can teachers be motivated by their students’ data in making stepwise changes to their teaching practices?

How do individuals make decisions? What determines the quality of group decisions? When and why do people cooperate with others? How does intergroup competition evolve?

In science, it is of vital importance that multiple studies corroborate the same result. Researchers therefore need to know all the details of previous experiments in order to implement the procedures as exactly as possible. However, this is becoming a major problem in neuroscience, as animal studies…

Analytical tools for environmental design and management in a systems perspective. The combined use of analytical tools.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

This article explores the concept of issue prioritisation within the context of public administration research, focusing on decision-making processes.

This paper develops a novel theoretical framework for the conduct of postmortems after major foreign policy surprises for the European Union and its member states.

PACES is an innovative, inter-disciplinary and multi-level research project that asks, How do changes in society, individual life experiences and migration policy shape decisions to stay or to migrate over time and across countries? And how can this knowledge inform future migration policies and gov…

How to explain the apparent high success rates of the EU infringement procedures, which are the major tools for enforcing EU law, against the member states?

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

The starting point for this research project is the notion that the human brain is susceptible to all kinds of fallacies and biases that affect our perceptions and influence our reasoning outside of our conscious awareness. Indeed, most people think they are merely observing facts and that they process…

Studies of perceptual decision-making typically present the same stimulus repeatedly over the course of an experimental session but ignore the order of these observations, assuming unrealistic stability of decision strategies over trials. However, even ‘stable,’ ‘steady-state,’ or ‘expert’ decision-making…

What will it be like to study at Leiden University in 2075? Ten surprising, artistic uni-visions could be brought to life. It’s up to you to vote for your favourite.

Research in Leiden University’s Institute of Political Science focuses on the dynamics and the interaction of political institutions, individual decision-making, and collective behaviour.

How do cognitive, motivational, and affective processes interact to select actions?

Nadine Raaphorst wrote an chapter for The Oxford Handbook of Administrative Justice about how two notions of fairness are studied in street-level bureaucracy literature and about the factors that influence how bureaucrats behave in this regard.

From 14 to 15 September 2023, Simona Demkova, AI researcher at the Europa Institute, participated in the INDIGO Project Final Conference, where she provided valuable perspectives on the implications of AI for European public law.

The focus of the Multicriteria Optimization and Decision Analysis (MODA) group is to develop foundations of methods in multi-objective optimization.

On 20 March 2019, Tim Dekkers defended his thesis 'Mobility, Control and Technology in Border Areas: Discretion and Decision-making in the Information Age'. The doctoral research was supervised by Prof. dr. J.P. van der Leun en Prof. dr. M.A.H. van der Woude.

KNOWMAK project aims at developing a web-based tool, which provides interactive visualisations and state-of-the-art indicators on knowledge co-creation in the European Research Area (ERA).

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration…

The coronacrisis is emerging as the ultimate test for political leaders. How do national political leaders get ahead or behind ‘the curve’ of fast-changing dynamics. Martin Lodge (London School of Economics and Political Science) and Arjen Boin (Leiden University Institute of Political Science) look…
