Contact the organizer to join this online seminar.

The weekly social event for PhD students, postdocs, and generally non-permanent research people at the ILLC is still on-going. Please feel free to join us! We meet for roughly 45 minutes and have an open informal discussion, often featuring a short (generally non-academic) presentation by one of the attendants on a topic of their choice.

LoC online seminar session on Wednesday, May 12 : Graham Priest on Mission Impossible.

As in previous editions, the purpose of this meeting is to inform you about issues that are currently of importance in the ILLC and/or the Master of Logic programme. We will also use this opportunity to welcome new members of staff and to provide you with an update about upcoming and other plans.

The Nordic Online Logic Seminar (NOL Seminar) is organised monthly over Zoom, with expository talks on topics of interest for the broader logic community. The seminar is open for professional or aspiring logicians and logic aficionados worldwide.

The full announcement for the next talk can be found in the link below. If you wish to receive the Zoom ID and password for it, as well as further announcements, please subscribe here:https://listserv.gu.se/sympa/subscribe/nordiclogic .

In this talk we will present a number of results stemming from a computational model of collective attitude formation through a combination of group deliberation and aggregation. In this model the participants repeatedly exchange and update their preferences over small sets of alternatives, until they reach a stable preference profile. When they do so the collective attitude is computed by pairwise majority voting. The model shows, on the one hand, that rational preference change can fill an existing gap in known mechanisms purported to explain how deliberation can help avoiding incoherent group preferences. On the other hand, the model also reveals that when the participants are sufficiently biased towards their own opinion, deliberation can actually create incoherent group rankings, against the received view. The model suggests furthermore that rational deliberation can exhibit high levels of path dependencies or "anchoring", where the group opinion is strongly dependent on the order in which the participants contribute to the discussion. We will finish by discussing possible trade-offs between such positive and negative features of group deliberation.

In this roundtable conversation, part of the Humane AI conversation series, Beate Rössler, Raquel Fernández and Max Welling will discuss topics related to AI ethics in teaching and research, moderated by Natali Helberger.

To mark its relaunch the VvL (Dutch Association for Logic and Philosophy of Exact Sciences) has the privilege to announce its first outreach event in 2021. It will take place on Friday 28 May 2021. We are very pleased to announce that Professor Moshe Y. Vardi (Rice University) will give a public lecture entitled And Logic Begat Computer Science.

This event will take place online using Zoom. The talk will be followed first by a short session where invited commentators will react to it, and later by a general Q & A session with the audience. The outreach event will be concluded by a social gathering on the virtual platform Gather.Town.

Registration is free, but necessary to receive links to Zoom and Gather.Town.
