Dear fellow social dilemma researchers,

We are happy to inform you that the next International Conference on Social Dilemmas (ICSD) will take place from July 2nd to July 5th, 2024, at Leiden University (the Netherlands). We hope to see you all there, so please mark your calendars!

Some background on the location: Leiden is a relatively small, beautiful city with a very rich history (dating back to the Roman empire) and a well-preserved historical center. Leiden University is the oldest in the Netherlands, founded in 1575. Also, Leiden has plenty of nice bars and restaurants , alongside its characteristic canals. It is very easy to reach (by plane, train, or any other way of transport), and very close to other larger Dutch cities (e.g., Amsterdam, Utrecht, Rotterdam, The Hague) as well as the Dutch coast. Moreover, Leiden is well-known for its active community of social dilemma researchers. As such, we believe it will be the perfect place for our next conference.

Further information about submission deadlines etcetera will follow at the end of 2023, via this mailing list and on the socialdilemma.com website.

If you already want to get first taste of the beauty of Leiden, see this clip.

Kind regards,

Also on behalf of the steering committee of the ICSD,

Erik W. de Kwaadsteniet

The Amsterdam-Copenhagen Cooperation Colloquia (AC3)

The Amsterdam-Copenhagen Cooperation Colloquia (AC3) are a series of online talks on interdisciplinary cooperation research. The series is sponsored by the Amsterdam Cooperation Lab at the Vrije Universiteit Amsterdam (PI Daniel Balliet) and the Personality and Social Psychology Group at the University of Copenhagen (PIs Robert Böhm and Ingo Zettler).

With the AC3, we aim to provide a forum for recent research on cooperation in humans and other animals. The series is interdisciplinary and international by design. The AC3 will feature speakers working in a wide range of disciplines (anthropology, biology, economics, psychology, etc.) and with a variety of methods (lab and field experiments, ethnography, experience sampling, computational modelling). We are especially committed to a diversity of speakers, including those who may otherwise face barriers to speaking at departmental colloquia.

The AC3 are organised by Shuxian Jin at the Vrije Universiteit Amsterdam and Simon Columbus at the University of Copenhagen. Please feel free to contact us in case you have any queries.

You can sign up for the colloquium series at: https://copsy.dk/ac3/
