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 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

ICSD 2022: Abstract submission deadline

Dear colleagues and friends,

We are happy to invite submissions for the International Conference on Social Dilemmas (ICSD), which will be held on July 19-22, 2022, in Copenhagen/Denmark.

Confirmed keynote speakers: Cornelia Betsch, Astrid Dannenberg, and Andreas Diekmann

Conference website with further information:

Submissions: Abstract submissions will be accepted via the conference website until February 1, 2022. Submissions will be evaluated in a double-blind procedure by independent referees.

This conference was originally planned for 2021. If you previously submitted an abstract and would like to re-submit this abstract, please re-submit it through the website. All submissions will be treated as new submissions.

We are planning to have a classic ‘offline’ conference. Depending on the COVID-19 situation and potential restrictions around travel, we will also offer online participation in a hybrid format. Hence, we invite everyone who is interested in participating to submit an abstract (a final decision about the format will be made in spring 2022, before the registration period).

We are excited to host ICSD 2022 in Copenhagen and hope to welcome many of you!

Save the date: ICSD 2022 in Copenhagen

Unfortunately, we had to cancel the 2021 conference for obvious reasons. The good news is that we have now scheduled a new date to have ICSD in Copenhagen in 2022 instead.

Please block your calendars for July 19-22, 2022. We will let you know once we’ve updated the website and you can submit new abstracts. The conference website can be found at:

Looking forward to welcome you to ICSD in Copenhagen next year!

International Conference on Social Dilemmas postponed to 2022

We would have loved to welcome you in Copenhagen this summer, but unfortunately, there will be no ICSD in 2021. In conjunction with the ICSD steering committee we have decided to reschedule the conference for 2022.

We initially hoped that it would be possible to hold an in-person or hybrid conference this summer. At the moment, however, it seems very unlikely that we could have a conference without severe limitations. Vaccination in many European countries runs slowly, and it is not clear whether all participants would be able to get vaccinated before the conference. Relatedly, it is unlikely that all restrictions on travel and events will be lifted until July. Even if people can get vaccinated and restrictions will be lifted, all of this would likely be decided only very shortly before the conference, leaving many participants in uncertainty until early summer.

Cancelling this year’s conference was a difficult decision for us. For those of you who submitted an abstract or already made plans to attend, we apologise for the inconvenience this causes you.

The exact date for next year’s conference will be determined after the summer. We will be in touch when the date has been set.

We are looking forward to welcoming you in Copenhagen in 2022.

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.
